What’s New?

• Plesk Migrator can now transfer the configured server-wide settings of mail and extensions, as well as those of the Plesk administrator’s profile when importing from supported Plesk servers (Plesk for Windows 17.0 or later, Plesk for Linux 12.0 or later for mail and administrator profile’s settings, Plesk for Linux 17.0 or later for extensions’ settings).
• (Plesk for Linux) On Plesk Obsidian servers with HTTP/3 support enabled, it is now possible to enable or disable HTTP/3 support on a per-domain basis. The “HTTP/3 support” checkbox can be found on any domain’s “Apache & nginx” page.

• Improved the Restricted Mode feature by adding new permissions to allow for more granular access control:

  • phpMyAdmin management grants or denies access to phpMyAdmin.
  • Mail bounce controls shows or hides the “Hide bounce controls” checkbox on the “Tools & Settings” > “Interface Management” page.
  • Hostname management allows or forbids changing the server’s hostname from the “Server Settings” screen.
  • Customize Plesk URL allows or forbids changing the Plesk URL via the “Tools & Settings” > “Customize Plesk URL” page.
  • Allow local FTP backups allows or forbids Plesk administrators to create backups in the local storage.
  • Website Log Check shows or hides the “Website Log Check” link on the “Tools & Settings” page.

  • Help Center shows or hides the “Help Center” link on the “Tools & Settings” page.

  In addition, the Support SSH Access, Advisor, Repair Kit, Log Browser, and Webserver Configurations Troubleshooter options restrict access to the corresponding extensions by hiding all related UI elements and restricting access via the URL.

Feature Improvements

• Added the following improvements to the SSL It! extension:

  • The extension now offers the option to secure the “mail” subdomain (for example, “mail.example.com”) when issuing an SSL/TLS certificate for domains with physical hosting (the “Website” and “Forwarding” hosting types).
  • Components that cannot be secured under the current configuration will not appear in the list of components to secure, even if they were secured previously.
  • The “Autorenew” feature no longer leaves an order unprocessed when a suitable certificate from storage is successfully assigned to the domain.
• The ability to upgrade MariaDB to version 11.4 via the Plesk GUI is now enabled on all Plesk Obsidian servers.
• (Plesk for Linux) mod_sftp is now shipped as a part of the Plesk proftpd package as a shared module. Users can now manually configure their SFTP access. The ability to configure it via the Plesk interface will be introduced in future Plesk releases.
• Added instructions to the mail helper on how to connect the Outlook for Microsoft 365 mail client.
• Removing a domain in Plesk no longer triggers updating its DNS zone.
• Made Plesk Installer more accessible by adding clearly visible focus indicators and making sure that Installer can be operated via keyboard only.

  [security]
  bruteforceProtection.enabled = true ;Enables or disables brute force protection.
  bruteforceProtection.rateLimit = 5 ;The number of failed access attempts allowed by an IP address.
  bruteforceProtection.rateLimitPeriod = 300 ;The rate limit period in seconds.
  

• (Plesk for Windows) Added a new components utility to allow users to manage server components from the CLI. To see help on the utility usage, run the following command:

• (Plesk for Linux) Updated Plesk images on Microsoft Azure, Google Cloud, DigitalOcean, Amazon Web Services (including Amazon Lightsail) from Ubuntu 22.04 to Ubuntu 24.04 LTS. See more information about available Plesk cloud images.

Feature Improvements

• Added the ability to resize interfaces and the installer up to 200% larger to improve accessibility.
• Limited how many tasks the Task Manager can query at one time and moved task cleanup jobs into batches to reduce CPU and RAM usage on high-load servers. This improves overall server performance. Also added debug messages for all Task Manager API operations.
• Improved Plesk QCOW2 images to take up less disk space on installation, scale more effectively with more storage, and contain security and packaging updates.

• Users can now configure the backup validation period by adding lines of the following pattern to the panel.ini file:

  [pmm]
  backupsValidationPeriod = 7 ;The backup validation period, in days.
  

  Note: Backup validation can be cancelled by setting backupsValidationPeriod to 0.

• (Plesk for Linux) Plesk now installs with a default secure TLS configuration.
• (Plesk for Linux) It is no longer possible to bypass the default PHP performance settings in PHP-FPM handlers using the .user.ini settings file or the PHP ini_set() command. The default PHP performance settings should be optimal for most websites, and changing the settings could impact the websites’ performance.

Deprecated and Removed Items

• (Plesk for Windows) Plesk removed support for BIND DNS due to security and maintenance risks.

  Note: If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS.

Windows

• Fixed the issue where opening the “Mail Accounts” page in Plesk resulted in the “Call to a member function getPackage() on null (WebmailPackage.php:59)” error for domains using Remote SmarterMail Web Client. (PPPM-14931)

Fixed Product Issues

• Fixed the issue where the phpMyAdmin button was missing from the database card in Dynamic List view after updating to Plesk Obsidian 18.0.69. (PPP-68197)

Fixed Product Issues

• Fixed the issue where, after updating to Plesk Obsidian 18.0.69, retrieving the list of databases owned by a subscription by clicking Databases in the Plesk GUI would result in the “Cannot read properties of undefined (reading ‘searchFilters’)” error if the number of databases was too high. (PPPM-14921)

What’s New?

• (Plesk for Windows) Plesk now supports Windows Server 2025.

  Note: Due to a limitation in Microsoft DNS on Windows Server 2025, it is not possible to create HTTPS and CAA DNS records in Plesk. Microsoft DNS on this version of Windows cannot load unknown record types from the zone file, which prevents support for these record types.

  Note: The ability to perform a dist-upgrade to Windows Server 2025 will be added in future Plesk releases.

• Added the “Password Reset Link”, which is now shown next to each email address on the “Email Addresses” tab. We updated the email addresses management screen to bring the most frequently used actions to the front. Since password reset is one of the most common tasks for subscription administrators, we redesigned this feature and placed it directly on the main email address management screen.
• (Plesk for Linux) Updated Plesk on Cloud DigitalOcean images from Ubuntu 22.04 to Ubuntu 24.04 LTS.

Feature Improvements

• Redesigned the way databases are displayed in Dynamic List view. The new interface is modern, robust, and user-friendly, offering smooth and fast transitions thanks to the use of drawers. This update marks a long-awaited step toward a unified experience based on Dynamic List view, paving the way for the eventual removal of the outdated Classic and Active list views.
• (Plesk for Windows) Replaced the auto-reply function developed by Plesk with native solutions provided by the supported mail servers. This improvement increases email sending and deliverability when DMARC, DKIM, and SPF are used.
  For details and recommended actions, see the Feature and Deprecation Plan.
• (Plesk for Linux)Performance Booster can now apply MySQL/MariaDB optimizations for MariaDB 11.4.

• (Plesk for Linux) Changed the GPG key used to sign Plesk packages and repositories to a stronger one. The new key prevents security warnings about weak algorithms during Plesk installations and updates. However, when installing the latest Plesk version on Ubuntu 24.04, you may still see warnings about a weak algorithm caused by the old GPG key in the following cases:

  • When Imunify extension repositories are configured, because the extension’s vendor (CloudLinux) has not yet updated their GPG key.
  • Briefly during Plesk Installer component initialization because it is required to enable all repositories to check the component availability.
  • When outdated versions of software shipped with Plesk are installed (for example, PHP versions earlier than 8.1), because they still use the old GPG key.

Deprecated and Removed Items

• The following outdated APS Catalog applications will be deprecated and removed from the Plesk APS catalog in Plesk Obsidian 18.0.71: DotNetNuke, Magento, Zen Cart, concrete5, phpList, osCommerce, Gallery, BBClone, SugarCRM, Coppermine, and SquirrelMail. For details and recommended actions, see the Feature and Deprecation Plan.
• The BIND DNS server has already been deprecated and removed from Plesk for Windows. Due to security and maintenance risks, we are taking steps to ensure that no Plesk servers continue using BIND as of Plesk Obsidian 18.0.70. If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
• Removed the Horde component from Plesk Installer. The component is no longer supported, and we recommend switching to another webmail software supported in Plesk.
• Removed RKHunter from the Watchdog extension. For details and recommended actions, see the Feature and Deprecation Plan.
• The following SDK functionality will be deprecated in Plesk Obsidian 18.0.69: implementation of the EventListener interface without the filterActions method. Starting from Plesk Obsidian 18.0.71, it will be mandatory to implement the filterActions method of the EventListener interface. See more details.

Fixed Product Issues

• Additional administrator accounts can no longer switch to Service Provider view when the “Force Power User view for additional administrator” feature is enabled. (PPP-68030)
• The version of the SOGo Webmail extension that supports PHP 8.4 no longer prevents website publishing with Web Presence Builder. (PPP-67950)

• Fixed regular updates of SpamAssassin databases. (PPPM-14888)
• The Watchdog extension now shows different statuses for “Not monitored” services, distinguishing between services that are not installed on the server and those not monitored due to the user’s choice. (EXTPLESK-8798)
• The Watchdog extension now correctly shows the actual RAM usage on the “Overall” line. (EXTPLESK-8793)
• Plesk now correctly shows and allows managing Docker containers created with the --ulimit memlock=-1 parameter. (EXTPLESK-6371)
• Improved an error message shown when a user tries to restore a subscription or website from a backup, but other subscriptions with the same domain name already exist on the server. (PPPM-14908)
• The Plesk administrator can no longer create a subscription that customers cannot manage by sending an XML API request with two shared IP addresses. (PPPM-14901)
• Plesk now shows the correct website traffic information taken from the current month. (PPPM-14885)

Linux

• Plesk REST API requests to the /databases and /dbusers endpoints again require no additional parameters. (PPPM-14904)
• Updating MariaDB to version 10.11 in Plesk on AlmaLinux no longer causes issues with log rotation. (PPPM-14895)
• It is no longer possible to install an unsupported BIND package in Plesk on AlmaLinux 9. (PPPM-14897)
• It is again possible to create Plesk backups and store them in a custom location on the server via the CLI. (PPPM-14889)
• Upgrading MariaDB in Plesk on AlmaLinux 9 no longer overwrites a user’s custom settings. Plesk now detects if the /etc/my.cnf.d/mariadb-server.cnf file contains customizations and stops the upgrade, allowing the user to move their settings to a separate configuration file. (PPPM-14886)
• An in-place upgrade of Plesk from CentOS 7 to AlmaLinux 8 no longer fails if the Watchdog and/or Plesk Migrator extensions are installed. (PPPM-14883)

• Disabling IPv6 in Plesk on AlmaLinux 9 no longer causes issues with the Roundcube password change. (PPPM-14795)
• The dist-upgrade from Plesk on Ubuntu 20 to Ubuntu 22 no longer fails if the Watchdog extension is not installed. (PPPM-14874)
• CentOS 7 to AlmaLinux 8 and CloudLinux7 to CloudLinux 8 conversion tools no longer install Roundcube if it was not previously installed. (PPPM-14867)
• The Plesk PHP Engine on Ubuntu 24 no longer encounters frequent shutdowns that generate false-positive status emails.
• Log Browser no longer shows empty placeholders instead of the actual service statuses. (EXTPLESK-8770)

  • Overhauled the extension graphical interface to make it modern and more convenient.
  • Removed the outdated “Security” tab. For security scans, use an alternative monitoring tool such as the Imunify extension.

• As per UserVoice request, we introduce the feature that prevents the creation of domains that resolve to another server. This enhances security, especially against phishing. The feature is available in Tools & Settings > Prohibited Domain Names (under “Security”).

  To hide the feature from the Plesk interface, add the following lines to the panel.ini file:

  [domainManagement]
  features.resolutionRestriction = false
  

• Plesk administrators and partners can now customize the mail helper, which assists users with connecting their mail clients to the “Mail Accounts” page. By editing the /usr/local/psa/admin/conf/email_client_configuration_instructions.md.sample Markdown file, they can customize the helper’s text, formatting, and links to better suit their customers’ needs. Learn more about customizing the mail helper.
• It is now possible to copy and share the mail helper by clicking the “Copy the setup wizard link” in the Plesk interface. With the link, users can configure their mail clients without having a Plesk account or logging in.

Feature Improvements

• It is now possible to change a domain’s mail service from “Not configured” to “Disabled for incoming mail” via the CLI.

• Enhanced the sync mechanism between reseller plans and resellers’ hosting plans with the following improvements:

  • Added validation for resources and permissions. A reseller can no longer save a service plan if it includes resources and permissions exceeding those granted by the Plesk administrator.
  • Permissions that are not granted by the Plesk administrator are now hidden from resellers.
  • When creating a reseller, the default plan is now automatically created, with resources and permissions within the limits set by the Plesk administrator.
• Improved the view of the domain card for “Forwarding” and “No hosting” domains. The domain card no longer has tabs: all controls are now shown in one place.
• Updated the Dynamic list tour to make it consistent with a new layout of the domain card.

• Improved the password generation process:

  • The “Copy” icon now appears immediately after a password is generated.
  • You can now copy a password directly, without clicking the “Show” icon and selecting the password first.

• Refined the way Plesk handles backup tasks in unstable environments with a range of improvements:

  • An incremental backup is now created instead of a full one if the last incremental backup failed. (PPPM-14774)

  This improvement is not enabled by default. You need to enable it manually by adding the following lines to the panel.ini file:

  [pmm]
  createFullAfterInvalidBackup = false
  

  By default, the old mechanism remains in place: a full backup is created if the latest incremental backup has failed.

  • Failed backups no longer break backup rotation and will be rotated according to the schedule. (PPPM-14776)
  • Incomplete backups are now marked as failed in the Plesk interface and deleted when the backup task is closed. (PPPM-14778)
  • Non-existent backups are now deleted without errors. (PPPM-14784, PPPM-14791, PPPM-14782)
  • Backups are now validated during rotation and when incremental backups are created. Non-readable backups are marked as invalid.
  • Backup volumes are now grouped into a single backup even if the first volume is absent.
  • Improved Plesk ability to delete incomplete backups by adding two parameters to the admin\share\pmmcli\pmmcli-rc file: MAX_FILES_DELETION_PERIOD and MIN_FILES_DELETION_ATTEMPTS. Plesk will now attempt to delete an incomplete backup within the number of days specified by the MAX_FILES_DELETION_PERIOD parameter. If the backup still exists after that period, the MIN_FILES_DELETION_ATTEMPTS parameter will take effect. This means Plesk will try to delete the backup at least as many times as the MIN_FILES_DELETION_ATTEMPTS value specifies. (PPPM-14786)
  • Streamlined backup error messages by removing empty lines and limiting their length. (PPPM-14780)
• (Plesk for Linux) Improved the way Plesk handles inconsistencies in package management tools (APT and DPKG) during Plesk updates. If such inconsistencies are detected, the update is blocked and Plesk provides a link to the instruction for manual resolution. (PPPM-14765)

Deprecated and Removed Items

• (Plesk for Windows) MySQL Connector/ODBC 3.51, 5.1, and 5.3 are no longer shipped with Plesk because they have reached end of life. MariaDB Connector/ODBC 64-bit 3.2.4 is now used instead.

• The Plesk Repair utility can now fix web server issues when the Plesk database is hosted on a remote database server. (PPPM-14699)
• If the panel.ini mailQueue.serverWide setting is set to true and Postfix is stopped, emails sent with the sendmail command are no longer incorrectly displayed with the “Sent” status and the [MailQueueList.Filter.Status.maildrop] locale key, instead of the actual text, in Tools & Settings > Mail Queue. (EXTPLESK-6366)
• Watchdog email notifications now contain information about the average CPU and RAM usage. (EXTPLESK-6392)
• It is no longer possible to apply unlimited resources in a service plan under specific circumstances if they are limited in the corresponding reseller plan. (PPPM-14627)
• The File Manager button is no longer absent for domains whose subscription is suspended. (PPPM-13978)

Linux

• Enabling the free Comodo rule set in ModSecurity now applies the default security rule IDs. (PPP-67522)

• System notes in Backup Manager no longer incorrectly show that a domain backup is a part of the server backup, when it is not. (PPPM-14771)
• The mailbox size set as the “Another size” option in the Plesk interface (Websites & Domains > domain > Mail Accounts > email address) now matches the mailbox size stored in the /var/qmail/mailnames/<domain>/admin/Maildir/maildirsize file. (PPPM-14767)

• The passenger-status command no longer fails with an error in Pleks on AlmaLinux 8 when the Phusion Passenger component is installed. (PPPM-14828)
• When IPv6 is enabled, opening the “Anonymous FTP” tab no longer results in an HTTP 500 error. (PPPM-14800)
• Automatic Plesk updates no longer fail on servers managed by Ubuntu Landscape. (PPPM-14849)

Windows

• Failure to back up a single email message no longer causes the entire domain’s mail backup to fail. (PPPM-14668)

This makes it possible to declare and build entirely custom containers. Any artefacts created during the build process will be placed inside the website’s Home directory.

• (Plesk for Linux) Added the ability to stop accepting mail sent to preconfigured aliases such as root, postmaster, or anonymous on Plesk servers using Postfix or qmail as the mail server. By default, such emails are delivered to the Plesk administrator’s mailbox.

  To allow accepting mail sent to one or more specific aliases, add the following lines to the panel.ini file, listing the desired aliases:

  [mail]
  adminAliases = alias1 alias2 .. aliasN
  

  Mail sent to aliases that are not listed will no longer be delivered to the Plesk administrator’s mailbox. For example, to allow accepting mail sent to the root and postmaster aliases, but not to any others, add the following:

What’s New?

• This release, we invested a lot of resources into improving Docker support in Plesk. We overhauled the Docker extension graphical interface to make it modern and more convenient, added Docker Compose support, fixed many pesky bugs, and more! Here are some of the highlights:

  • As per UserVoice request, it is now possible to deploy Docker Compose YAML files (but not Dockerfiles or any other files required by an application), and also to modify and update the stacks from the new “Stacks” tab. Use copy and paste, or upload them from local storage. Typical operations on stacks are supported, such as: up (including pull and force-recreate), stop, and down.
  • The main Docker page was split into the “Containers” and “Images” tabs.
  • The “Configurations” page is now the “Environments” tab.
  • The ability to pull images was added to the extension’s interface.
  • As per UserVoice request, Docker containers’ configuration (but not data in Docker volumes) is now included in Plesk backups.

  To enable these features, add the following lines to the panel.ini file:

  [ext-docker]
  newUI = on
  

• Added a helper to assist users with connecting their mail clients to the “Mail Accounts” page. The Configure Mail Clients button helps users turn on autodiscover, and also provides concise instructions on how to connect their Mozilla Thunderbird, Gmail on Android, iOS Mail, or Outlook 2016 or earlier client to their Plesk mailboxes.

• As per UserVoice request, added the ability to quickly empty mailboxes of all mail to the “Mail Accounts” page. The Empty Mailbox button enables users to remove all mail, both incoming and outgoing, from one or more mailboxes with a click.

  • The ability to deactivate MFA for dependent users was added.
  • The MFA secret key is now regenerated when the MFA feature is reactivated for a user.

• We are glad to introduce the beta version of the WHMCS Installer extension. The extension helps you install and configure WHMCS by guiding you through the essential steps: installing PHP and ionCube Loader, configuring and installing WHMCS, creating the database, and securing the system.

  We would love to hear your feedback about this extension at beta-extensions@plesk.com.

• (Plesk for Windows) MariaDB 11.4 is now supported. It is the latest “long-term support” version from the vendor. Support for MariaDB 11.4 in Plesk for Linux was added in Plesk Obsidian 18.0.64.

Feature Improvements

• (Plesk for Linux) The Performance Booster feature will be rolled out to all supported Plesk Obsidian installations. The feature enables Plesk administrators to tweak PHP, web server, and database server settings to significantly improve the hosted websites’ performance.

What’s New?

• We are excited to announce the launch of our updated “What’s New” page for Plesk! The page highlights the key features and major benefits of Plesk Obsidian helping you to gain a deeper understanding of our product. Explore it now at What’s New in Plesk Obsidian.
• As per UserVoice request, it is now possible to configure a smarthost or relayhost in Plesk on the server level. For details, refer to the following topic.
• (Plesk for Linux) MariaDB 11.4 is now supported. It is the latest “long-term support” version from the vendor.
• (Plesk for Linux) The Website Log Check feature will be gradually rolled out to all Plesk Obsidian installations version 18.0.64 and later. The feature helps to troubleshoot a website’s availability issues by scanning the web server logs for common issues and suggesting ways to resolve them. Learn more about Website Log Check.

• The new customizable Home dashboard in Service Provider View is now enabled by default on all Plesk Obsidian servers. It helps you to keep track of your server and your business by adding, removing, and rearranging informational blocks showing all sorts of data. To disable the feature, add the following lines to the panel.ini file:

  [navigation]
  newHomeView.enabled = false
  

• As per UserVoice request, to the Docker extension, added support for AlmaLinux 9 and support for websocket traffic on Docker Proxy Rules.

• Improved the dist-upgrade procedure and migration:

  • From Plesk on Ubuntu 20 by introducing PHP 7.3 provided by Plesk.
  • From Plesk on Ubuntu 22 by introducing PHP 7.0 provided by Plesk.
  • From Plesk on Debian 11 by introducing PHP 7.2 provided by Plesk.

  Websites after migration or dist-upgrade now seamlessly adopt a new PHP version without additional manual patches.

  Note: PHP versions 7.0 - 7.3 are outdated and no longer supported by the vendor (PHP Group), so they will receive no security updates. We recommend that you use these old PHP versions only for the dist-upgrade or migration purposes, and then switch to a newer supported PHP version.

• With the upgrade to Plesk Obsidian 18.0.64, Kaspersky Anti-Virus for Servers will be automatically removed from the servers it is installed on. We recommend that you migrate to Sophos Anti-Virus for Servers. It is fully integrated with Plesk for both Linux and Windows, and also included in Power Pack and Hosting Pack.
• The CloudLinux team extended the Imunify360 extension with the improved ImunifyAV/AV+ and renamed the Imunify360 extension to Imunify. Existing users of the free and paid ImunifyAV extension (the revisium-antivirus ID) can upgrade to the new ImunifyAV/AV+ at no additional cost. Learn more about benefits of the revamped Imunify and how to upgrade to it.

Feature Improvements

• The Plesk Repair feature in the UI can now fix MariaDB/MySQL server permissions.

• Revamped the Disk Space section in the Repair Kit extension:

  • Disk and Plesk directories are now shown in the Disk Space section.
  • Warnings and alerts are now shown only for disks that contain the directories mentioned above.
  • Added a message with general recommendations on what to do if the disk space is not sufficient.

• Improved the Track Email Delivery feature in Websites & Domains > domain > the “Mail” tab. If there are one or more delayed emails in the queue, an orange circle is now shown next to the “Mail” tab name.

  To disable this feature, add the following lines to the panel.ini file:

  [ext-log-browser]
  showEmailBadge = false
  

• As per UserVoice request, in the Plesk DNSSEC extension, introduced CLI commands to sign, unsign, and show the current settings of a DNS zone. See the examples of use below:

  • To sign a domain with default settings:

    plesk ext dnssec sign –domain-name example.com

  • To view DNSSEC information for a domain:

    plesk ext dnssec info –domain-name example.com

  • To unsign a domain:

    plesk ext dnssec unsign –domain-name example.com

• Added the following options to the ModSecurity CLI: -waf-rule-filter-ids, -waf-filter-by-tags, -waf-filter-by-regexp, and -waf-additional-settings. For details, see the CLI guides for Linux and Windows.
• Unified and updated the messages shown when Plesk license limits are reached. The messages about upgrading a Plesk license to a higher version are now more helpful, clear, and informative.
• The Node.js Toolkit now supports JavaScript modules (MJS files).
• It is now possible to use the “Forgot password” feature via the CLI: the plesk bin admin --send-reset-link command with the -user or -email options generates a password reset link for the specified user and sends it via email.

Future Plans

• Starting from Plesk Obsidian 18.0.65, the ImunifyAV extension will be removed from the Recommended and Full presets. Instead, the Imunify extension (former Imunify360) will be installed by default on all new Plesk installations. If, for some reason, you want to disable the extension, add the following lines to the panel.ini file:

  [extensions]
  blacklist = imunify360
  

• The Horde webmail has been deprecated. Its complete removal is scheduled on April 2025. For details and recommended actions, see the Feature and Deprecation Plan.

• Updated Roundcube 1.4.15 to fix the CVE-2024-42008, CVE-2024-42009 and CVE-2024-42010 vulnerabilities.

What’s New?

• (Plesk for Linux) We are glad to present the “InnoDB repair” tool you can use to check for and attempt to automatically fix InnoDB corruption in MariaDB databases. InnoDB corruption is a serious issue, preventing the database server from working properly. Fixing it by hand requires time and expertise.

  You can access the tool by browsing https://:8443/repair/ and authenticating with the Plesk administrator credentials.

• Re-worked the “Mail Queue” menu to make it easier to track the status of messages and identify and resolve issues.

  To enable this feature, add the following lines to the panel.ini file:

• We are glad to present a tool to convert your CloudLinux 7 servers to CloudLinux 8! The ready to use CLI tool is available in our GitHub repository.

• Plesk Obsidian on Ubuntu 20.04, AlmaLinux 8, and AlmaLinux 9 now comes with PHP 7.0 support. PHP 7.0 can be installed via Plesk Installer.

  This should make updating servers running an earlier OS version smoother. However, keep in mind that PHP 7.0 is outdated, and no longer receives security updates. We recommend updating web applications that require PHP 7.0 to use up-to-date PHP versions.

• You can now resell Sitejet Commerce. To do so, add the following lines to the panel.ini file:

  [ext-plesk-sitejet]
  commerceEnabled=true
  commerceBuyUrl=https://example.com/link-to-the-commerce-product-in-your-store
  

• Implemented a feature in Sitejet that enables users to seamlessly substitute a missing logo with text (and switch back to a logo if necessary).
• The Hungarian language is now available for the Sitejet Website Builder interface
• New Sitejet website template: Eco-Con.
• New Sitejet website template: WePaint.

Feature Improvements

• On Plesk Obsidian servers with a custom DNS backend enabled, Plesk now sends the following messages to the custom integration script:

  • A “create” message when a domain is created.
  • A “delete” message when a domain is removed.
  • An “update” message when a domain is suspended, disabled, or enabled, or when a domain’s DNS service is enabled or disabled, or when the Plesk DNS service for a domain is switched from primary to secondary, or vice versa.

  To enable this feature, add the following lines to the panel.ini file:

  [dns]
  newEvents = true
  

• Added a tooltip to the domain-level “Track Email Delivery” pages explaining why it is not possible to resend or remove sent, rejected, and bounced emails.
• Added a tooltip to the domain-level “Track Email Delivery” pages advising to select one or more deferred emails when attempting to click Resend with no deferred emails selected.
• The support for DNS HTTPS records is now enabled by default on all Plesk Obsidian servers.
• The pre-configured firewall rules in Plesk cloud images were updated to enable HTTP/3 to work out of the box.
• The “CPU usage” and “Memory usage” informational blocks on the new Home dashboard no longer take a long time to load the data. In addition, the “Memory usage” informational block now shows the total amount of RAM on the server.
• The Performance Booster extension now regularly checks the current database server settings and notifies the Plesk administrator when a noticeable improvement in performance can be achieved by applying the recommended settings.
• Increased the size of the input window when creating a “Fetch a URL” type scheduled task to make working with a long URL more convenient.

• It is now possible to manually configure the maximum age of mail log entries to be processed by the Log Browser extension (in seconds). To do so, add the following lines to the panel.ini file:

  [ext-log-browser]
  mailQueue.firstEntryOffset = <value in seconds>
  

Linux

• The Fail2ban bad bots list has been updated.
• Added the ability to manually add IP addresses to the Fail2ban banned IP addresses list, both temporarily and permanently.
• Pseudo-devices with constant 100% disk usage (such as /dev/loop devices) are no longer shown in Tools & Settings > Server Information to avoid unnecessary confusion.
• Added support for the Atomic ModSecurity rule sets in Plesk on AlmaLinux 9.

Future Plans

• Kaspersky Anti-Virus for Servers has been deprecated and is no longer available for installation. Starting from Plesk Obsidian 18.0.64, the extension will be automatically removed from the servers it is installed on. For details and recommended actions, see the Feature and Deprecation Plan and the deprecation FAQ.

Fixed Product Issues

• Fixed the issue where, on Ubuntu 24.04 servers, log entries about emails present in the server-wide mail log were absent from the domain-level “Track Email Delivery” pages. (EXTPLESK-5616)
• Fixed the issue where emails sometimes showed the confusing “MailQueueList.Filter.Status.null” status on the domain-level “Track Email Delivery” pages. (EXTPLESK-5612)
• Fixed the issue where the Log Browser extension got stuck trying to process logs with an excessively large number of entries. (EXTPLESK-5686)
• The Action Log now records changes made to the Action Log settings, including changing what actions are included in or excluded from the log, and also changing the log rotation settings. (PPP-65724)
• Fixed the issue where customers could see actions performed by other customers in the Action Log. (EXTPLESK-5654)

• Fixed the issue where a domain’s DNS zone could not be updated under specific circumstances. (PPPM-14503)
• Fixed the issue where a main account’s settings could not be updated under specific circumstances.(PPPM-14501)
• Fixed the issue where restoring one or more domains with DKIM enabled from backup on a Plesk Obsidian server with DKIM disabled in server-wide mail server settings failed with the “Unable to restore domain keys” error. (PPPM-14499)
• Fixed the issue where the $ character could be used in the names of protected directories, which resulted in broken nginx configuration. (PPPM-14485)
• Fixed the issue where selecting an SSL/TLS certificate for a domain removed the “Not selected” option from the “Certificate” drop-down menu, making it impossible to unassign the certificate. (PPPM-14481)
• Fixed the issue where additional administrator accounts had access to Mail server settings and Spam filter in Tools & Settings even if Restricted Mode with default settings was in effect. (PPPM-14478)
• Fixed the issue where setting a new default SSL/TLS certificate in Tools & Settings > SSL/TLS certificates resulted in the IPv6 address being removed from Apache and nginx configuration files for webmail. (PPPM-14323)
• Fixed the issue where the utility sanitizing the content of technical reports could fail under specific circumstances. (PPPM-14522)
• Fixed the issue where renaming a domain using PHP version 8.0.30 with the “Dedicated FPM application served by nginx/apache” handler resulted in the PHP worker process for that domain being unable to start. (PPPM-14513)
• Fixed the issue where, on AlmaLinux 8 servers, scanning the server with Rootkit Hunter resulted in unnecessary and misleading errors in the /var/log/rkhunter.log file. (PPPM-14494)

Linux

• Fixed the issue where, on servers running on Ubuntu 20.04, no DNS-related operations resulted in changes being made to the DNS zone files. (PPP-65747)

What’s New?

• (Plesk for Linux) Introducing the “TuxCare Extended Lifecycle Support” extension for Plesk servers running on Ubuntu 18.04 or CentOS 7 that have reached end of life. The extension configures TuxCare ELS system package manager repositories, from which your Plesk Obsidian server will be receiving security updates, system enhancement patches, and bug fixes.

Fixed Product Issues

• (Plesk for Linux) Switched the CentOS 7 yum repositories to vault.centos.org because the OS has reached end of life. That way it will still be possible to install system packages on Plesk servers running on CentOS 7. (PPP-65508)

  Note: This change does not affect custom mirrors for CentOS 7 yum repositories.

Fixed Product Issues

• (Plesk for Linux) Switched the CentOS 7 yum repositories to vault.centos.org because the OS has reached end of life. That way it will still be possible to install system packages on Plesk servers running on CentOS 7. (PPP-65508)

  Note: This change does not affect custom mirrors for CentOS 7 yum repositories.

What’s New?

• Introducing the Extended Lifecycle Support (ELS) program designed to give you more time and a peace of mind before migrating your Plesk server from an EOL operating system to a supported one. This program will run:

  • CentOS 7 & CloudLinux 7 – until January 1, 2026 (vendor EOL date - June 2, 2024)
  • Ubuntu 18.04 & Debian 10 – until July 1, 2025 (vendor EOL dates - September 2024 for Ubuntu 18.04, June 2, 2024 for Debian 10)

  Plesk will continue releasing updates and providing technical support for these OSes beyond the vendor EOL dates, until the dates specified. Supporting EOL OSes incurs additional development and maintenance costs, and so taking advantage of this offer will cost extra. We strongly recommend migrating or dist-upgrading to supported OSes.

• We are happy to introduce the new 1.8.0 version of the Log Browser extension. In the new version, Plesk customers (as well as Plesk administrators) can track email delivery and manage deferred emails right in the domain card (under the “Mail” tab).

  The feature is available only in Plesk for Linux (except for Ubuntu 24.04) with Postfix used as an MTA.

  We will gradually enable the feature on Plesk servers starting from June 24, 2024. You can enable the feature manually in advance by adding the following lines to the panel.ini file:

  [ext-log-browser] 
  mailQueue.customerAccess = true
  

  By default, information about emails with the “Rejected” status is removed from the extension’s database after 48 hours to prevent rapid growth of the database. If you need to set another period for storing this information, you can always add the following lines to the panel.ini file:

  [ext-log-browser] 
  mailQueue.rejectedRemovalPeriod = 172800 ; in seconds
  

  Note: The feature works on top of the journald service and follows the server-wide log configuration. If the logs are rotated or removed, information about the emails will also be unavailable. Processing the logs for the first time may consume extra server resources. Afterward, the extension will process only changed data every hour.

• Plesk is now fully compatible with the security.txt standard, which defines the way both independent security researchers and your clients can get in touch with you about security concerns and vulnerabilities they have found in Plesk domains.

  With the new Native security.txt compliance extension, you can generate one common security.txt file for all domains hosted on your Plesk server. Once you generate the file and enable the feature, Plesk will continuously maintain it. Learn how to enable the feature and generate the file in our documentation.

  Note: In case you need more flexibility in configuring the file's content, you can use the extension created by LJPc solutions.

• Added the new tile blocks and improvements to our New Home Dashboard:

  • Added the SSL It! block that contains the consolidated status of certificates on your Plesk server to help you avoid their sudden expiration.
  • Added the block for the “Advisor” extension that helps you monitor the state of your Plesk server.

• Added support for HTTPS DNS records as an alternative to CNAME records. For example, you can use HTTPS records for naked domains, for which CNAME records are not supported.

  The feature can be managed in the Plesk user interface, using the plesk bin dns CLI commands, or using API requests.

  In Plesk Obsidian 18.0.62, the feature is disabled by default. You can manually enable it by adding the following lines to the panel.ini file:

  [dns]
  records.https.enabled = true
  

Linux

• Added an ability to install and remove PHP 5.6 from Plesk servers running on AlmaLinux 8 and 9 via Plesk Installer. That way you do not have to switch websites running on PHP 5.6 to a supported PHP version before the migration and thus avoid possible errors.

  Note: PHP 5.6 is EOL and does not receive important security fixes. We do recommend that you switch your websites to a supported PHP version after migration.

Feature Improvements

• Navigation between most-used pages in Plesk has become 3 times faster.
• On the “Serverwide” tab of Performance Booster, it is now possible to apply one or several database server improvements instead of applying them all together.

• Introduced the following improvements to the SFTP Backup extension:

  • Added the ability to use the Ed25519 public-key authentication and custom SSH keys.
  • Added the ability to update SSH keys.

• Starting from Plesk Obsidian 18.0.62, requests to REST API containing the Content-Type header with a media-type directive other than “application/json” will result in the HTTP “415 Unsupported Media Type” client error response code. Since the curl commands send the “Content-Type: application/x-www-form-urlencoded” header by default, you need to add the --header "Content-Type: application/json" option to such commands to keep them working correctly.

  We strongly recommend that you check your existing integrations that use cURL for compliance with this change and update them if necessary. Failure to do so may result in any such integrations ceasing to work after updating to Plesk Obsidian 18.0.62.

Windows

• Added the Log Browser extension to the Recommended and Full presets.

Fixed Product Issues

• Fixed the following issues in the Multi-Factor Authentication extension:

  • The extension once again correctly remembers a device and no longer asks for authentication if the “Remember this device for 30 days” checkbox was selected before. (EXTPLESK-5556)
  • The plesk ext mfa config info CLI command now works with accounts of additional administrators and SMB users. (EXTPLESK-5559)
• Fixed the issue where the “Spam filter sensitivity” field in the domain email's settings was empty if the “0” value was specified during creation of the email address. (PPPM-14470)
• Customers no longer can change the hosting type of their subscriptions without corresponding permissions. (PPPM-14466)
• Switching between views in Plesk on mobile devices once again works correctly. (PPPM-14450)
• Resellers can once again create custom buttons. (PPPM-14441)
• Changing the admin user's password is once again properly logged. (PPPM-14428)
• Calculating statistics of a domain's database with the dash symbol in its name no longer fails with an error. (PPPM-14420)
• Wappspector no longer creates a clickable WP Toolkit icon for a domain, whose service plan has the WP Toolkit permissions disabled. (PPPM-14347)
• Fixed the issue where the Log Browser extension was logging the “PHP Warning: Undefined array key “Extension Version” error by mistake under specific circumstances. (EXTPLESK-5376)
• Resellers can once again create hosting of domains. Previously the issue occurred because the “Username” field on the “Hosting Settings” page of a domain became unavailable if the “Customers can change the name of their system users” option was set to “Never”. (PPPM-14468)

• When an email template is used in Mailman 3, emails are once again delivered to email addresses from a mailing list. (PPPM-14370)
• Updating the GeoIP data has become more safe because the old data will now be used if any errors occur during the update. (PPPM-14454)
• When the email sender's address contains the < and/or > symbols, it is once again displayed correctly in the “From” field of a forwarded email. (PPPM-14438)
• We increased the limit of text that one can paste in SSH Terminal from 512 bytes to 4 kilobytes so that this no longer breaks the connection. (PPPM-14422)
• In Plesk on AlmaLinux 9, the /var/log/maillog log file is no longer rotated to prevent collecting incorrect statistics. (PPPM-14415)
• If a sub-directory is protected with its own password and Apache is disabled for the domain, it is no longer possible to access that sub-directory using the password for the parent directory. (PPPM-14410)
• The removed old IP address of a Plesk server is no longer restored in the /etc/hosts file after assigning a new IP address and changing the hostname. (PPPM-14405)
• To prevent overuse of server resources, the number of concurrent sw-engine requests when opening the “Domains” page is limited to 12. (PPPM-14400)
• Fixed incorrect logging of DNS-related events under specific circumstances. (PPPM-14342)
• The Plesk repair utility once again warns if the last Plesk upgrade has failed for some reason. (PPPM-14177)

Windows

• The same permissions are once again assigned to the \MySQL\my.ini file both when a custom or default path for storing user data is specified during the Plesk installation. (PPPM-14460)
• Fixed the issue where it was impossible to secure a domain using the SSL/TLS certificate if the MailEnable service was running under a user account with insufficient privileges. (PPPM-14458)

• Fixed the issue where accessing the Plesk web interface after updating to Plesk Obsidian 18.0.61 resulted in the “array_key_exists(): Argument #2 ($array) must be of type array, false given” error if one or more custom buttons pointing to an email address existed in Plesk prior to the update. (PPPM-14444)

Linux

• The MariaDB upgrade tool can no longer be used to upgrade the database server on servers running outdated Linux kernel versions, which resulted in the database server failing to start after the upgrade. (PPP-65096)

Changes in Third-Party Components

Linux

• Updated Roundcube to version 1.6.7.

• (Plesk for Linux) To resolve certain issues related to HTTP/3 support, the following changes have been made:

  • For the time being, HTTP/3 support for the Plesk panel itself (but not the hosted websites) is disabled. All aspects of HTTP/3 support are to be treated as experimental until further notice.
  • Installing this update will disable HTTP/3 support for your the Plesk panel if it has been enabled previously.
  • On newly installed Plesk Obsidian servers, HTTP/3 support is no longer enabled automatically for hosted websites, but can still be enabled manually.

Fixed Product Issues

• Clicking on the count of resellers in Tools & Settings > IP Addresses no longer results in an error. (PPPM-14426)

Fixed Product Issues

• (Plesk for Linux) Logging in to Plesk via the TCP port 443 no longer results in an unwanted redirect to the port 8880 and the “This site can’t provide a secure connection” error. (PPP-64958)

What’s New?

• (Plesk for Linux) Ubuntu 24.04 is now supported on x86-64 architecture, with certain limitations. Learn more about the Ubuntu 24.04 support limitations.

  ARM-based servers are not supported at the moment.

• (Plesk for Linux) HTTP/3 (nginx) is now supported for hosted websites. Learn more about HTTP/3 support in Plesk.

  Note: HTTP/3 is not supported on CentOS 7 and Ubuntu 18.

• We are glad to announce the new Multi-Factor Authentication (MFA) extension, coming to Plesk Obsidian 18.0.61 and later. The new extension is meant to offer seamless 2FA authentication to all Plesk users, and comes with the following benefits:

  • Multi-factor authentication can now be configured in the profile settings for users of all levels (administrators, additional administrators, resellers, customers, and subscription users).
  • Plesk administrators can now make multi-factor authentication mandatory for all Plesk users on a server. Learn more about making multi-factor authentication mandatory.
  • The Multi-Factor Authentication (MFA) extension is added to the Recommended preset.

• We are glad to announce the fully revamped, customizable Home dashboard in Service Provider View. Keep track of your server and your business by adding, removing, and rearranging informational blocks showing all sorts of data. At the moment, the following blocks are available:

  • Plesk version - Plesk version and information about any available updates.
  • Server Information - Server hostname, IP address, OS, and uptime.
  • Last server backup - The status of server backup and backup schedule.
  • Performance Booster - Available server and website performance optimizations.
  • What’s New - Latest entries from the Plesk changelog.
  • IP Address Banning - The status of the Fail2Ban service.
  • Mail Queue - The status of the email queue (Postfix only).
  • Promo - Information about possible customizations and additional features.
  • CPU usage - Daily CPU usage information.
  • Memory usage - Daily memory usage information.
  • Subscriptions with overuse - The list of subscriptions with resource overuse.
  • My subscription - Subscriptions owned by the administrator.
  • Custom Buttons - display custom buttons added by the administrator.

  The feature is currently in beta. To enable it, add the following lines to the panel.ini file:

  [navigation]
  newHomeView.enabled = true
  

  We would love to hear your feedback about the new Home page at feedback@plesk.com.

• The WordPress single-site management operations from WP Toolkit are now fully integrated into the Dynamic list and shown by default for WordPress websites. If you want to continue managing your WordPress websites from WP Toolkit, you can disable this feature by adding the following lines to the panel.ini file:

  [ext-wp-toolkit]
  appModeFeature = off
  

• (Plesk for Windows) It is now possible to in-place upgrade Windows Server 2012 R2 servers running Plesk to Windows Server 2019. Learn more about in-place upgrading Windows Server 2012 R2 servers.

Feature Improvements

• Added the ability to manage the settings of scheduled backups (both server-wide and at the subscription level) via the CLI. Learn more about managing scheduled backups via the CLI.
• Added the ability to manage the settings of scheduled tasks (both server-wide and at the subscription level) via the CLI.
• Added PHP 8.3 to the Recommended preset. Also, removed PHP 8.1 from the Recommended preset.
• Improved error reporting in certain places of the Plesk GUI. Now, when there is an error, the browser screen is automatically scrolled to the top of the page, where a more detailed informational message is shown instead of a generic “Internal server error” one.

Future Plans

• Starting from Plesk Obsidian 18.0.62, requests to REST API containing the Content-Type header with a media-type directive other than “application/json” will result in the HTTP “415 Unsupported Media Type” client error response code. Since the curl commands send the “Content-Type: application/x-www-form-urlencoded” header by default, you need to add the --header "Content-Type: application/json" option to such commands to keep them working correctly.

  We strongly recommend that you check your existing integrations that use cURL for compliance with this change and update them if necessary. Failure to do so may result in any such integrations ceasing to work after updating to Plesk Obsidian 18.0.62.

• Introducing Extended Lifecycle Support (ELS). We understand that migrating to a new operating system can be a complex process. To give you more time and a peace of mind, we’re introducing the Extended Lifecycle Support (ELS) program. This program will run:

  • CentOS 7 & CloudLinux 7 – until January 1, 2026 (vendor EOL date - June 2, 2024)
  • Ubuntu 18.04 & Debian 10 – until July 1, 2025 (vendor EOL dates - September 2024 for Ubuntu 18.04, June 2, 2024 for Debian 10)

  Plesk will continue releasing updates and providing technical support for these OSes beyond the vendor EOL dates, until the dates specified. Supporting EOL OSes incurs additional development and maintenance costs, and so taking advantage of this offer will cost extra. We strongly recommend migrating or dist-upgrading to supported OSes.

Fixed Product Issues

• Fixed the issue where changing a subscription’s IP address via the plesk bin subscription command failed for domains that had their hosting type set to “no web hosting”. (PPPM-14343)
• Fixed the issue where the “Create Website” button was shown for domains that had no access to any of the website creation tools in Plesk. (PPPM-14380)
• Fixed the issue where creating a MySQL database via the plesk bin database command while passing an encrypted database user password to it via the PSA_CRYPTED_PASSWORD environment variable failed with the “Syntax error or access violation” error. (PPPM-14384)

Linux

• Fixed the issue where renaming a subscription’s system user on a Plesk server with the Cgroups Manager extension installed failed with the “usermod: user xxx is currently used by process xxxxx” error. (PPPM-14291)

• Fixed the issue where reading or rereading IP addresses on a server connected to OpenVPN added the IP addresses of TUN interfaces to the list of IP addresses available in Plesk. (PPPM-7965)

  Implementing the fix requires adding the following lines to the panel.ini file:

  [networkInterfaces]
  blacklist = tun*,tap*
  

• Fixed the issue where restoring from a corrupted backup file produced the unclear “Perhaps /usr/local/psa/admin/bin/deployer application missing, has incorrect permissions or unexpectedly terminated” error after failing. (PPPM-14118)
• Fixed the issue where running the plesk repair web command added the IP addresses of running Docker Compose containers to the Plesk nginx configuration files. (PPPM-14337)
• Fixed the issue where Plesk installation failed if an RDS Aurora MySQL instance was specified as the Plesk database server. (PPPM-14354)
• Fixed the issue where updating Plesk on a server hosting a large number of websites produced an unnecessary and misleading “Nginx has not restarted during upgrade due to failure of configuration test” warning. (PPP-64510)
• Fixed the issue where a custom Plesk installation produced an unnecessary and misleading “Failed to restart mailman3.service: Unit mailman3.service not found.” warning in the installer log file. (PPPM-14377)
• Fixed the issue where restoring individual objects (for example, files) from a backup resulted in old cronjobs being restored as well. (PPPM-14387)
• Fixed the issue where running the plesk repair web command did not restore the PHP-FPM configuration. (PPP-64844)
• Fixed the issue where renaming subscription system users and additional FTP users could sometimes fail with the “user xxx is currently used by process xxxxx” error. (PPPM-10717)
• Fixed the issue where, after renaming a subscription’s system user failed, the domain’s PHP FPM handler’s pool became corrupted, and no new domains using the same PHP handler could be created. (PPP-63258)
• Fixed the issue where .NET applications failed to work if SELinux was enabled on the server. (PPPM-14378)

Windows

• Fixed the issue where accessing a symlink in File Manager resulted in the “Unable to open the directory: Symlinks out of webspace are prohibited” error. (PPPM-14399)
• Fixed the issue where the custom “open_basedir” value failed to take effect for websites with a custom document root. (PPPM-14390)

Changes in Third-Party Components

Fixed Product Issues

• It is again possible to upgrade Plesk Onyx to Plesk Obsidian. (PPPM-14396)

What’s New?

• To help Plesk users comply with the NIS2 directive, and also to improve the security of Plesk in general, the NIS2 compliance mode makes a number of changes to what is logged to the Plesk Action Log. Learn more about NIS2 compliance mode.

  To enable NIS2 compliance mode, add the following lines to the panel.ini file:

  [actionLog]
  nis2compliant = true
  

  Once you have done so, the following changes take effect:

  • API requests are now logged to the Action Log. To also log API requests that only get information from Plesk and do not result in any changes being made, add the following line to the [actionLog] section:

    api.includeImmutable = true
    

  • Changes to DNS records are now logged to the Action Log, including the specifics (such as what record was added or removed, or what changes were made to an existing record), as well as the GUID of the user who made the change.

  • Action Log is now included in Plesk backups if the “User files” checkbox is selected when creating a backup, and the “Exclude log files” one is not. Customer or reseller level backups only include information pertinent to that customer/reseller.

    Action Log is stored in a separate file with the backup_action-log prefix. Learn how to extract files from a Plesk backup.

• (Plesk for Linux) We are glad to announce that the ability to upgrade MariaDB database servers to the latest version in the LTS branch via the Plesk interface is no longer in beta! We thank everyone who tried the beta version for their participation and feedback.

  To access this feature, go to Tools & Settings > Database Servers (under “Applications & Databases”), and then click Upgrade Now next to an eligible MariaDB database server.

  The feature is being gradually rolled out to Plesk servers around the world. If you do not see the Upgrade Now button, you can enable the feature manually by adding the following lines to the panel.ini file:

  [databaseManagement]
  features.canBeUpgraded = true
  

• Plesk customers can now get access to Plesk Action Log events related to their subscriptions to monitor changes applied to them. The feature works only together with the Log Browser extension and will be enabled gradually after the release of Plesk Obsidian 18.0.60. The link to Action Log will appear in the right menu near the domain card.

  We consider the feature to be a mandatory requirement for Plesk to comply with the NIS2 directive. According to the directive, customers must have an ability to monitor changes related to their domains.

  To enable the feature before its official release in Plesk Obsidian 18.0.60, add the following lines to the panel.ini file:

  [actionLog]
  actionLogForEndUsers = true
  

  Note: If you have already enabled the nis2complience setting in the panel.ini file, no need to enable actionLogForEndUsers as well. nis2complience enables all features related to compliance with the NIS2 directive.

• Full-featured integration of WP Toolkit into Plesk Dynamic list is now available.

  To enable this feature, add the following lines to the panel.ini file:

  [ext-wp-toolkit]
  appModeFeature = on
  

  Once you have done so, most WP Toolkit features (except for mass management operations) become accessible directly from Dynamic list in Plesk without having to open WP Toolkit.

• Added the “Get Started” tab to domain cards in Dynamic List view to make it easier for new users to build websites quickly. It offers many options for creating a website with just one click (like Sitejet, WordPress, Laravel, Node.js, and more). The tab appears when opening a newly created domain’s card for the first time, and remains accessible but nonintrusive once closed. The tab replaces both the previously available “Welcome” panel and the “Create website” button.
• It is now possible to buy Plesk licenses straight from the DigitalOcean Marketplace interface and attach them to new and existing droplets.
• With the new paid Sitejet Commerce feature that supports integration with Ecwid, you can now have an eCommerce store on your Sitejet-based website.
• Sophos Anti-Virus for Servers can now be installed via Plesk Installer on both Plesk for Linux and Plesk for Windows servers. You can find it in the “Mail hosting” section in Plesk for Linux, and in the “Anti-Virus features” section in Plesk for Windows.
• The latest 30 entries from the Plesk Obsidian changelog are now available in an RSS feed. You can find the feed here.

Feature Improvements

• The “Scheduled Backups List” extension has been localized into 31 languages: Arabic, Catalan, Chinese Simplified, Chinese Traditional, Czech, Danish, Dutch, Filipino, Finnish, French, German, Greek, Hebrew, Hungarian, Indonesian, Italian, Japanese, Korean, Malay, Norwegian Bokmal, Polish, Portuguese, Portuguese, Brazilian, Romanian, Russian, Spanish, Swedish, Thai, Turkish, Ukrainian, and Vietnamese.
• The Plesk interface and documentation now mention both MariaDB and MySQL where only MySQL was mentioned before.

Linux

• Plesk now shows the exact amount of physical memory installed on the server. To access this information, go to Tools & Settings > Server Information (under “Server Management”), scroll down to “Memory Usage”, and look for the “Hardware” column.
• When trying to update Plesk on a server that does not have enough free disk space, Plesk Installer automatically cleans up unnecessary temporary files, then tries again.
• The “NTP Timesync” extension is now included in the “Recommended” preset.
• A separate branch of the “NTP Timesync” extension was created so that the extension could still be installed on Red Hat Enterprise Linux 6.x. Future versions of the “NTP Timesync” extension’s main branch will no longer be compatible with Red Hat Enterprise Linux 6.x.
• The “NTP Timesync” extension has been localized into 30 languages: Arabic, Catalan, Chinese Simplified, Chinese Traditional, Czech, Danish, Dutch, Finnish, French, German, Greek, Hebrew, Hungarian, Indonesian, Italian, Japanese, Korean, Norwegian Bokmal, Polish, Portuguese, Portuguese, Brazilian, Romanian, Russian, Spanish, Swedish, Thai, Turkish, Ukrainian, and Vietnamese.
• Added a message in Tools & Settings > Mail Server Settings advising to set the value of the “Maximum message size” parameter to 135-140% of the maximum allowable attachment size.

Windows

• It is now possible to install and use the Log Browser extension in Plesk for Windows. The extension also provides access to Action Log events for customers the same way it is done in Plesk for Linux.

Future Plans

• (For developers of extensions) Starting from Plesk Obsidian 18.0.61, we plan to switch PHP used by Plesk to PHP 8.3. If you are running any custom extensions, you will need to update them to support PHP 8.3 to avoid potential issues.

  You can install Plesk Obsidian 18.0.60 running on PHP 8.3 for testing purposes only by running the following command:

  wget https://autoinstall.plesk.com/plesk-installer && bash ./plesk-installer install plesk 18.0.60 --source http://autoinstall.plesk.com/plesk-php8.3
  

• Starting from Plesk Obsidian 18.0.62, requests to REST API containing the Content-Type header with a media-type directive other than “application/json” will result in the HTTP “415 Unsupported Media Type” client error response code. Since the curl commands send the “Content-Type: application/x-www-form-urlencoded” header by default, you need to add the --header "Content-Type: application/json" option to such commands to keep them working correctly.

Deprecated and Removed Items

• Starting from Plesk Obsidian 18.0.60, the ability to use Active List view will be removed. All customers will be automatically switched to Dynamic List view.

Windows

• Starting from Plesk Obsidian for Windows 18.0.60, it will no longer be possible to install the BIND DNS server, or to select it as the default DNS server in Tools & Settings > Server Components. Our support team will also no longer provide answers to questions related to the BIND DNS server in Plesk for Windows.

  We strongly recommend that you switch to Microsoft DNS.

Fixed Product Issues

• Fixed the issue where restoring a subscription with one or more add-on domains from a backup created in Plesk Obsidian 18.0.54 or earlier resulted in domain keys not being configured for the add-on domains. (PPPM-14299)
• Fixed the issue where restoring from a backup in remote storage resulted in the creation of that backup in local storage. That backup counted against the subscription’s disk space limit, but could not be seen in Backup Manager if the subscription lacked the permission to manage local backups. (PPPM-14287)
• Fixed the issue where trying to optimize PHP Settings for a domain with one or more disabled and/or broken PHP handlers resulted in the “Failed to update the optimal settings: [[app.conflicts.app.conflicts.Overview]]” error. (PPPM-14348)

Linux

• On servers running Red Hat Enterprise Linux or one of its derivatives, when trying to upgrade the MariaDB database server via the Plesk interface, the upgrade tool now verifies the configured repositories before starting and notifies the user if any of them must be commented out or removed for the upgrade to succeed. (PPP-64366)
• Fixed the issue where running the plesk bin ipmanage --remap command resulted in one or more lines in the map file being ignored if one or more target IP addresses already existed on the target network interface. (PPPM-14353)

• PHP 7.4 is now correctly marked with the “Outdated” tag in the Plesk Installer interface. (PPPM-14263)
• When installing Plesk on Debian or Ubuntu, “Recommended” dependencies (including the sa-compile package) are no longer installed. (PPPM-14367)
• Fixed the issue where, after registering a custom DNS backend via the plesk bin server_dns --enable-custom-backend command, adding a DNS record in Plesk did not result in the record’s TTL value being passed to the custom backend. (PPPM-14366)
• Fixed the issue where SSH access was shown as “Forbidden” on a domain’s Hosting page if the hosting plan the domain’s subscription was based on had the “SSH access to the server shell under the subscription’s system user” parameter set to /bin/bash and the “Management of access to the server over SSH” permission to “Not allowed”. (PPPM-14360)
• Fixed the issue where, if the permissions on the /etc/domainkeys directory were wrong, running the the plesk repair fs command produced the “Class “Plesk\Repair\Fs\PleskUserException” not found” error instead of fixing them. (PPPM-14358)
• Fixed the issue where, if outgoing mail control was enabled, emails using the “windows-1253” character set were delivered with malformed contents. (PPPM-14355)
• Fixed the issue where running the plesk repair web --php-handlers command to fix missing PHP handlers assigned to service plans failed to remove the “The following PHP version(s) are not installed” error shown on the Tools & Settings > PHP Settings page. (PPPM-14350)
• Fixed the issue where running the plesk repair mail command did not fix the DKIM configuration. (PPPM-14299)
• Editing a symlink to a file in File Manager now correctly saves the changes in the file the symlink is pointing to. (PPPM-14345)
• Fixed the issue where trying to set an image in the SVG format as the custom login screen background failed with the “Some fields are empty or contain an improper value” error. (PPPM-14341)
• Fixed the issue where removing a subscription failed to also remove the DKIM configuration files of domain aliases owned by the removed subscription. (PPPM-14324)

• (Plesk for Linux) We are happy to announce the support for Mailman 3 in Plesk on Debian 11 and Debian 12. Read more about Mailman 3 in Plesk.
• (Plesk for Windows) We are happy to introduce the new PowerShell Terminal extension in Plesk for Windows that allows connecting to PowerShell right in the Plesk user interface without having to use RDP connection to the server.
• The Plesk GUI now supports HTTP/2, which improves web performance, optimize resource use, and reduces browsing latency.

• In Service Provider view, we added the count of customers, resellers, domains, subscriptions, and service plans to the left menu. That way you can quickly see how many business items exist on the server. You can disable the feature by adding the following lines to the panel.ini file:

Feature Improvements

• Significantly improved the performance of Dynamic List view on configurations with many domains. Our tests on configurations with 100 domains within one subscription shows a fourfold improvement in the page loading speed. It is now possible to interact with loaded elements without having to wait for the entire page to load, which means no more freezing.

  We have also significantly improved the domain search speed.

Our support team will also no longer provide answers to questions related to BIND DNS.

  We strongly recommend that you switch to Microsoft DNS.
