• Replaced Gzip with ZSTD as the default compression method for backup and restore operations in Plesk. On multi-CPU servers, depending on the type of data being backed up, this provides the following benefits:

  • Reduces the backup size by up to 20%.
  • Reduces the CPU load by up to 25%.
  • Reduces the backup creation time by up to 2x (fast), and by up to 4x (fastest), based on the compression level.

  The desired compression level can be set in “Tools&Settings” > “Backup Manager” > “Settings”. The ‘Fast’ level is set by default.

• Added the ability to disable automatic HTTP > HTTPS redirection for webmail. To enable it, add the following lines to the panel.ini file:

  [mail]
  webmail.forceHttp = true
  

  On Plesk for Windows, to disable automatic HTTP > HTTPS webmail redirection for existing domains, run the plesk repair web -webmail command.

• Removed a number of Plesk extensions from the Plesk Installer due to low usage. These extensions are still available from the Extensions Catalog:

  • Domain Connect
  • Social Login

  In addition, the Plesk Cgroups Manager extension was removed from the “Recommended” preset, and the Site Import extension was added to the “Recommended” preset.

• Due to security improvements made by Google, if you are using Google Drive Backup Plesk extension to create backups on a shared drive belonging to a corporate account, you need to do the following to be able to make backups (users with personal drives are unaffected):

  • Make sure your administrator has marked the Plesk Backup Corporate application as trusted.
• Plesk Administrator should explicitly specify their country of residence in their profile.

• Added the ability for Outgoing Mail Control to count the number of individual recipients (TO, CC, and BCC) instead of messages. This closes an abusable loophole which allows users to send bulk email by specifying a large number of recipients (the current Outgoing Mail Control logic counts each individual email as just one message sent, no matter how many recipients the email is sent to). To switch Outgoing Mail Control from counting messages to counting recipients (and vice versa), run the plesk bin mailserver --set-outgoing-messages-count-recipients <true|false> command (the change is server wide). (PPM-7181)
• Specifying custom values for both the proxy_read_timeout nginx directive and max_execution_time PHP setting for the same domain results in the max_execution_time value being substituted for the proxy_read_timeout value (e.g., adding proxy_read_timeout 1800; to “Apache&Nginx Settings” > “Additional Nginx directives” and setting max_execution_time to 90 in “PHP Settings” will result in proxy_read_timeout being set to 90 in the nginx configuration file for the domain in question).

• Added a human readable error message for cases when Task Manager fails to show the list of current tasks due to the number of simultaneously running tasks being very high. (PPPM-13123)
• Running the plesk bin pleskbackup command with the “-z” or “no-gzip” options now correctly results in the backup file not being compressed. (PPPM-13254)

The mailbox size is now corectly shown as “Default” instead of “Another size” in Plesk, and is changed accordingly for all mailboxes if the size limit is changed in the hosting plan. (PPPM-13274)
• The size of files smaller than 4 KB is now shown correctly in File Manager. (PPPM-13303)
• The “Upload file” command is no longer shown in File Manager when browsing a read-only directory. (PPPM-13285)
• Copying a database or exporting a database dump no longer fails if the name of the database starts with the dash (“-“) character. (PPPM-13267)

Windows

• Mail Autodiscover is no longer supported for Microsoft Outlook 2019 and O365 versions. These mail clients use Microsoft proxy servers for autodiscover requests, and this configuration is not is supported in Plesk.
• Added password validation to the plesk bin database-server CLI utility. It is no longer possible to set database server password containing non-printable characters which caused issues with web statistics generation. (PPPM-12972)
• It is now possible to create a subdomain for an additional domain with hosting type set to “no hosting”. (PPPM-12952)
• Changing the language on the Plesk login page and then clicking the “Forgot password?” link no longer results in the password recovery page using the Plesk default language instead of the language chosen on the login page. (PPPM-12943)
• Setting the number of automatic replies Plesk can send to a unique email address per day to more than 100 no longer results in an error. (PPPM-12434)
• Trying to create a domain when the maximum number of domains allowed by the Plesk license or the reseller plan has already been reached no longer results in a blank screen. (PPPM-13030, PPPM-13043)

• Added the ability to check the statuses of all emails sent to and from a Plesk server by reviewing the maillog and filtering by date, source, or any string pattern. It is also possible to check the maillog in real-time (‘tail -fn0’ analog). To use this feature, install the Mail Log Browser extension.
• Added the option to automatically remove emails forwarded from a mailbox in Plesk. The feature is disabled by default. To enable it, go to “Mail”, click the desired mailbox, open the “Forwarding” tab and select the “Do not deliver copies of forwarded emails to the Plesk mailbox” checkbox.
• systemd-cron is now supported on Debian 9/10 and Ubuntu 18.04/20.04. The cron package can now be replaced with systemd-cron on servers with Plesk using the OS package manager. systemd-cron is a wrapper that converts cron tasks to systemd “timers”, which solves the well-known issue with a lot of emails being sent after a failed cron job.
• Dovecot now reloads the configuration files instead of restarting whenever a mail certificate is renewed. This should resolve the issue with IMAP/SMTP connections often being closed without warning on Plesk servers hosting many domains.
• The default chroot settings are no longer changed after updating Plesk to the latest version. (PPPM-12885)
• The plesk repair utility no longer fails on file system check if the virtual host directory has been changed. (PPPM-12602)
• Running the plesk repair utility no longer results in a misleading suggestion to repair incorrect permissions if the virtual host directory has been changed. (PPPM-12325)
• On Debian/Ubuntu servers with Plesk PHP session files are now cleaned up properly if PHP from the OS repository is not installed on the server. (PPPM-13022)
• Fai2ban no longer fails while processing the “plesk-panel” jail if debug mode is enabled in Plesk. (PPPM-13051)
• Updating PHP packages from Remi’s RPM repository no longer resets permissions on /var/lib/php/session potentially causing PHP websites to malfunction. (PPPM-13068)
• Converting a CentOS server with Plesk to AlmaLinux no longer fails if the EPEL repository is enabled on the server. (PPP-53540)

Windows

• MariaDB error logs no longer contain misleading “Aborted connection” warnings related to the plesksrv service. (PPPM-12737
• Errors encountered during Plesk update are now correctly recorded in the installer log. (PPP-52706)
• Restoring a password-protected subscription backup created on another Plesk server no longer fails if the correct password is provided. (PPPM-13061)

Third-Party Component Updates

  • The “Webspace settings” section is now pre-filled and collapsed.

  • By default, Plesk now hides the Let’s Encrypt and Git sections when users create subscriptions, domains, and subdomains. To make the sections visible, add the following lines to the panel.ini file:

      [ext-sslit]
      enableSecuringNewDomain = true ; shows the "Secure with an SSL/TLS Certificate" section
      secure-new-domain = true ; makes the "Secure the domain with Let's Encrypt" checkbox selected by default

• Added a progress screen shown when users create domains.
• Cleaned up the Plesk onboarding: removed distractions (for example, Plesk update notifications) that used to be shown once Plesk is installed.
• Improved protection against open redirect. The trustedRedirectHosts setting now has the default “empty” value on all existing and new Plesk installations. trustedRedirectHosts specified with the “empty” value forbids Plesk from redirecting to any hosts using the success_redirect_url and failure_redirect_url parameters because such redirecting poses a security risk.
• Plesk no longer shows DNS Helper if either IPv4 or IPv6 address resolves to the Plesk server. (PPP-52686)
• Improved the message shown when a domain name is resolved to the IP address different from the Plesk server IP. The message no longer misleadingly states that the website is offline. (PPPM-12937)
• When file upload fails in File Manager, Plesk now shows a detailed error message instead of the [[fileNotUploaded]] locale key. (PPPM-12929)
• Backing up to the Microsoft OneDrive Backup storage can no longer fail because of a failed request for a new OneDrive access token. (EXTPLESK-2654)

• It is now possible to remove the Plesk email address of a subscription’s additional users if an external email address is specified. (PPPM-12849)
• Restarting the Plesk server in Tools & Settings no longer causes the “Failed to fetch” warning to be shown in the Plesk interface. (PPPM-12962)
• It is now possible to create a subdomain of an add-on domain that has the forwarding hosting type via API-RPC. (PPPM-10784)
• The pleskbackup utility used with the --domains-name command no longer backs up the whole server instead of a subscription if the specified subscription does not exist. (PPPM-12797)

Linux

• It is now possible to create a subdomain of a disabled domain if the “Force daily log rotation for all domains” server setting is turned on. (PPPM-11930)
• Webmail is now turned on by default for domains created via API-RPC. (PPPM-12355)
• The plesk repair utility now fixes incorrect permissions in /usr/local/psa/PMM/rsessions, which in turn fixes backup and restoration logs. (PPPM-12786)
• If a domain’s IPv6 address is set to “none”, running the plesk repair db utility no longer shows the false positive “The following domains are assigned to already removed IP addresses.” error message. (PPPM-12988)
• A system user that uses the “bash (chrooted)” shell can no longer lose the ability to connect via SFTP. (PPPM-12969)
• Plesk now daily rotates PHP-FPM error logs to prevent them from consuming all the server disk space and eventually causing issues on the server. (PPPM-11362)
• Fail2ban logs and database backups can no longer consume all the server disk space. (PPPM-12981)
• Suspending a subscription that has an add-on domain with the forwarding hosting type and a subdomain of the add-on domain no longer breaks the Apache configuration. (PPPM-12939)
• nginx now returns a 404 Not Found error when requesting a non-existent static file larger than 1023 bytes whose URL contains a trailing slash. (PPP-53248)
• Disabling a domain whose webmail service was uninstalled no longer generates an incorrect webmail configuration. (PPPM-12984)
• Removing the /usr/local/psa/PMM/rsessions directory and then going to Backup Manager no longer prevents further backup restoration and download of restoration logs. (PPPM-12785)
• In Plesk on Ubuntu with libc6 version 2.31-0ubuntu9.3 or later, a subscription’s system user that uses the “bash (chrooted)” shell can now connect to the Plesk server. (PPPM-12954)
• Subscriptions’ system users that use the /bin/false shell now log in to the Plesk server via FTP faster. (PPPM-12909)
• In Plesk on a Debian-based system, rereading IP address to repair misconfigured ones no longer duplicates IP addresses in /etc/network/interfaces. (PPPM-12941)
• If Plesk with Postfix that uses milter_protocol=2 receives an email, this no longer kills the pc-remote service. (PPP-53325)
• Plesk Log Browser now displays logs compressed in the GZIP format. (PPPM-12976)
• Plesk now correctly applies locale keys of non-English Horde interface languages. (PPPM-12886)

• Apache now runs if it is configured with TLS 1.3 ciphers only. (PPPM-12964)
• Plesk now vacuums the Fail2ban database weekly to prevent it from growing large. (PPPM-12981)

Windows

• Plesk no longer fails to create mail for a subscription that belongs to the service plan that has a disabled webmail client selected. (PPPM-12968)
• Changes in the %plesk_dir%MySQL\my.ini file no longer prevent updating Plesk Onyx to Plesk Obsidian. (PPPM-12994)
• Improved the error message shown when Plesk cannot restore a remote SFTP backup because one or more database server types (for example, Microsoft SQL Server) present on the remote storage server are not present on the Plesk server the backup is being restored on. (PPPM-12974)
• It is now possible to turn on the Atomic Standard rule set in ModSecurity. (PPPM-13001)
• The plesk repair mail utility no longer fails if the “DNS zones for DNSBL service” server-wide mail setting field contains a long string. (PPPM-13002)
• Plesk now changes a domain’s PHP version in the IIS configuration files even if the PHP handler was previously uninstalled. (PPPM-12911)
• The %plesk_dir%MySQL\Data*.err file can no longer contain errors and warnings related to the PleskWebSocket service. (PPPM-12737)

• In Plesk with enabled “DNS Helper”, the “DNS Settings” page of domains created under subscriptions without hosting no longer shows the “Internal Error” message. (PPP-52966)

Linux

• It is now again possible to enable ModSecurity with the “Comodo (free)” rule set in the Plesk interface. (PPP-52965)

• In File Manager, it is now possible to do the following:

  • Upload directories.
  • (Plesk for Linux) Change file permissions recursively. Plesk for Windows has always supported that.
• File Manager can now display SVG files.
• Improved the interface of Dynamic List view. It is now easier to distinguish one domain card from another because we made the separating lines more distinct.
• Reduced the domain creation time by four seconds. To achieve this, we split the mail service creation into a separate task.
• Improved the “Add Domain” page. Plesk now automatically fills in the system user name and password boxes. We have also removed the password confirmation box.
• The “Mail Settings” page of domains now shows a hint how to enable DKIM signing for an external DNS server. The hint shows the exact DNS records users need to add to the DNS server.
• It is now possible to get information about subdomains via the CLI or REST API. (PPPM-12825)
• Enabling the mail service via the CLI for a subdomain no longer creates the Plesk database inconsistency. (PPPM-12836)
• Disabling the domain resolution check in panel.ini now hides the “Domain is not resolvable” message under “DNS Settings” of domains. (PPPM-12891)
• The window shown after closing the Change View item in the left navigation pane now contains a correct text instead of placeholders. (PPPM-12863)
• It is no longer possible to cause the Plesk database inconsistency by deleting an IP address assigned to a subscription without hosing. (PPPM-12876)

• Introduced a new CLI command --assign-database, which assigns a database created via the API to a domain. (PPP-52056) The command has the following pattern:

  plesk bin subscription_settings --assign-database <domain_name> -database-id <database-id>
  

• The “DNS settings” page of a subscription no longer fails to be opened with HTTP Error 500 if the Plesk database inconsistency occurs. (PPPM-12877)
• Plesk can now restore backups of subdomains that belong to a domain with the forwarding hosting type. (PPPM-12903)
• Improved a hint for creating temporary domains. The previous hint was incorrect and could mislead users into specifying a temporary domain name that did not work. (PPPM-12883)
• Updating to Plesk Obsidian no longer fails if the /var/www/vhosts/ permissions are not sufficient. (PPPM-12872)
• Removing an APS application can no longer cause the Plesk database inconsistency. (PPPM-12902)
• The “DNS Settings” page of a non-resolvable domain can no longer show the “Unable to find subscription” error instead of a warning that the domain name does not resolve to the server IP address. (PPPM-12871)
• The Plesk interface can no longer occasionally show the “Cannot read property ‘querySelector’ of null” error. (PPPM-12884)
• If a service plan has the “Switch on the mail service” and “Enable mail autodiscover” mail settings disabled, subscriptions created on the basis of the service plan now inherit these disabled mail settings. (PPPM-12879)

• If “DNS Helper” is enabled and an add-on domain has an alias, panel.log no longer contains confusing error messages. (PPPM-12906)
• The plesk repair utility now detects issues with domains assigned to already removed IP addresses and suggests reassigning the domains to existing IP addresses. (PPPM-12865)
• Improved a message shown after a Plesk password reset. (PPPM-12677)
• File Manager can now display the content of files whose names contain Cyrillic characters. (PPPM-12897)
• The pmmcli utility now ignores Error 152 and shows the path to the imported backup dump because the error does not actually affect the backup dump import. (PPP-52707)
• The pmm-ras utility no longer creates archives and migration.log in the current working directory. The utility now creates migration.log in PMM_LOGS_D if the --session-path is not specified. The utility operation before the bugfix could occasionally cause server backups to fail. (PPPM-11752)
• Sped up loading of lists with a large number of domains (more than 1000). (PPPM-12689)

Linux

• Plesk can now be installed on AlmaLinux OS.

• Dropped support for Ubuntu 16.04.
• Improved an error message shown when IP addresses registered in Plesk do not match those set up on the server and this mismatch caused an issue with the web server. The message now contains the link to the KB article with the steps on how to fix the issue.
• Updating Plesk 18.0.33 and earlier to the latest Plesk version no longer causes Plesk Premium Antivirus to start sending false notifications that a Plesk Premium Antivirus license will expire soon. (PPP-52338)
• Mail delivery to IDN emails no longer fails. (PPPM-12866)
• Removed an unnecessary test run during Plesk installation. The failed test created a log warning message with a recommendation to check the network configuration. The test result affected neither Plesk installation nor performance. (PPP-41762)
• Plesk now preserves the following custom settings of the [php-fpm-pool-settings] section in additional php.ini directives: chroot, clear_env, decorate_workers_output. (PPPM-12666)
• phpMyAdmin can no longer show strange users without passwords (for example, the user “Any”). (PPPM-12793)

• Plesk now correctly counts statistics for an add-on domain not including statistics for the domain with the same name as the add-on domain (if any). (PPPM-12577)

Windows

• For an external SMTP server used with Plesk, it is now possible to use a non-email username instead of a full email address (for example, just “mail” instead of “mail@example.com”). (PPPM-12896)
• The Plesk Installer output now shows all characters of a package version. (PPPM-12842)
• Removed a warning message about a 900-second delay after a PHP version change. (PPPM-12831)

• If the Windows system locale language is not English, Plesk no longer skips a subscription’s mail when backing up the subscription. (PPPM-12874)
• It is now again possible to train SpamAssassin because SpamAssassin Imap.php no longer tries to connect to the localhost using TLS. (PPPM-12086)
• Improved error reporting if backup creation fails with the “Failed to create archive: Repository error”. (PPPM-12697)

  Note: Although the issue was fixed, we recommend that you disable Rocket Loader. It does not benefit Plesk in any way.

Linux

• Updating the Plesk server OS using dist-upgrade and updating Plesk Obsidian with Postfix installed to version 18.0.34 no longer breaks the Postfix configuration. (PPPM-12846)
• In Plesk Obsidian 18.0.34 and later, the Plesk administrator no longer receives daily emails from the Plesk cron task notifying that “ls: cannot open directory /usr/lib64/httpd/modules”. (PPPM-12853)

• Updating Plesk Obsidian to version 18.0.34 no longer fails with the “Plesk database scheme was not upgraded completely” error if the Plesk server has the specific time zone set. (PPPM-12837)

• Added the Recycle Bin to File Manager. Users can now restore files deleted by mistake from the Recycle Bin.
  The Recycle Bin is turned off by default. To turn it on, add the following lines to the panel.ini file:

  [fileManager]
  trash.enabled = true
  trash.folder = .trash ; the name of the the Recycle Bin folder
  

  The Recycle Bin appears when a user deletes a file and chooses not to delete it permanently.

• The “DNS Helper” and “Publicly resolvable temporary domain name” features introduced in Plesk Obsidian 18.0.32 will be enabled by default strating with Plesk Obsidian 18.0.34. To disable the features, add the following lines to the panel.ini file:

  [dns]
  enableResolveChecking = false ; disables resolve checking
  showDnsHelper = false ; hides DNS Helper
  [techDomain]
  subdomain.enabled = false ; removes the ability to create technical domains
  

• Even if no DNS server is installed, Plesk will now show the information about configuring DNS for domains that could not be resolved.
• Significantly sped up Plesk initialization and post-install configuration.
• Revamped file editing in File Manager. Users now edit files in a drawer instead of going to a new page.
• The image preview feature in File Manager works again in Plesk and the feature no longer needs the Image Preview extension. If the Image Preview extension is installed, updating Plesk to version 18.0.34 will remove the extension.
• Plesk UI notifications on ModSecurity rule set updates are no longer enabled by default. The Plesk administrator now explicitly turns on the notifications if necessary.
• If the Comodo rule set is not available for download because of an issue on the waf.comodo.com side, Plesk now shows an error message that describes what users can do.
• Tools & Settings > Active Plesk Sessions (under “Security”) now differentiates sessions of the Plesk administrator and additional administrators. Additionally, Plesk now shows the “Another user with the same username (admin) is already logged in to Plesk” warning only if a user of the same type is logged in. (PPPM-6227)
• It is now possible to add a description to a domain when creating the domain via REST API. (EXTREST-127)
• The plesk repair db command can now fix the default certificate inconsistencies in the Plesk database. (PPPM-12795)
• Plesk additional administrators can now change their passwords in Power User view. (PPPM-12316)
• After logging in to Plesk updated to the latest version, the “Too few arguments to function Plesk_Base_Utils_Http::getUserIp()…” error is no longer occasionally shown. (PPPM-12696)
• It is now again possible to create backups stored in FTP storage. This feature was broken since Plesk 18.0.33. (PPPM-12699)
• Plesk sw-engine now correctly uses the system time zone defined in Tools & Settings > System time (under “General Settings”) As a result, after the system time zone was changed, sw-engine now operates in the correct time zone and writes log entries that have the correct time. (PPPM-12543)
• In the output of the secret_key CLI utility, changed the “Key” field name to “Key ID” to avoid user confusion. (PPP-52085)

• The plesk repair mail <domain> command can now repair a mailbox even if the mailbox automatic reply contains non-ASCII characters.

• Clean installations of Plesk 18.0.33 and later no longer have database inconsistencies. (PPPM-12806)

  Note: If you got a new Plesk 18.0.33 or later, run the plesk repair db command to fix the inconsistencies. Updating Plesk to version 18.0.34 will not automatically fix them.

• After a domain was deleted or its hosting type was changed to forwarding, the Plesk database no longer has nginx.conf records left. (PPPM-12758)
• Users can no longer get Dr.Web notifications on the upcoming expiration of their Dr.Web license even though the license has already been updated in Plesk. (PPPM-12761)
• Applying the DNS template to all DNS zones no longer changes empty TTL values of the affected DNS records to 0. (PPPM-12752)

• Installation or update of Plesk Obsidian 18.0.31 no longer fails in non-interactive mode if the server OS is CentOS 8.2 or 8.3. (PPPM-12582)

• PHP 8.0 is now supported.

  Note: PHP 8 is still very recent (it came out on November 26) and includes significant changes, including the removal of deprecated functions and changes to how code works.

  Because of this, many PHP applications that were written for PHP 5 and PHP 7 may not work correctly with PHP 8. This includes WordPress, which will fix most (but not all) PHP 8 compatibility issues in version 5.6 that will be released on December 8.

  PHP 8 will not be included into the “Recommended” installation set and won’t be installed on new servers or when updating to Plesk Obsidian 18.0.32.

• DNS Helper - a new feature meant to help users understand that their domain does not resolve to the server’s IP address and is inaccessible over the internet, and also to make it easier for them to make their domain resolve correctly. The feature will be rolled out to Plesk servers in waves. To enable it manually, add the following lines to the panel.ini file:

  [dns]
  enableResolveChecking = true
  showDnsHelper = true
  

• Added a new CLI command plesk checkupgrade in both Plesk for Linux and Plesk for Windows. Running the command before updating Plesk checks for issues that may prevent the server from updating safely.
• Added the support for ModSecurity 3 to nginx. ModSecurity 2.9 + Apache remains for now the recommended option. To switch to ModSecurity 3 + nginx, go to “Tools&Settings” > “Web Application firewall”.
  • Switching to ModSecurity 3 may hinder your existing applications. We strongly recommend trying ModSecurity 3 out on a test server before switching your production environment to that version.
  • At the moment you can only choose the OWASP ruleset in the Plesk UI for ModSecurity 3. You can download the Comodo ruleset and upload it to Plesk as a custom ruleset. We plan to make it possible to enable the Comodo ruleset for ModSecurity 3 directly from the Plesk UI in Plesk Obsidian 18.0.33.

  • You can disable switching to ModSecurity 3 by adding the following lines to the panel.ini file:

    [modSecurity] webServer.nginx = Off

• This version introduces a guided onboarding workflow to help new users create their first website right after the new server initialization stage. Users can choose to start with a WordPress website, a PHP application, or a static HTML/CSS website. They can upload a website they already have or choose a sample website provided with Plesk. To disable this function, add the following lines to the panel.ini file:

  [ext-onboarding]
  enabled = 0
  

• As of Plesk Obsidian 18.0.32, Internet Explorer 11 support has been deprecated and will be removed in Plesk Obsidian 18.0.33. Learn more.

To enable it manually, add the following lines to the panel.ini file:

  [techDomain]
  subdomain.enabled = true

• Restoring a backup created on a Plesk server with a large (1000+) number of customers and/or subscriptions no longer fails with the “The specified backup file is corrupted, modified, created on another server or in an earlier Plesk version” error. (PPPM-12461)

Linux

• Creating a domain for a subscription while simultaneously changing PHP settings for an existing domain belonging to the same subscription no longer results in both processes hanging endlessly. (PPPM-12447)

• Plesk no longer assigns the system privilege “Replace a process level token” to IIS users created by Plesk. We believe this to be a more secure configuration, despite it being recommended by Microsoft.
• Plesk also explicitly removes the privilege “Impersonate a client after authentication” from IIS_IUSRS group. We believe this to be a more secure configuration, despite it being recommended by Microsoft.
• On Plesk servers with SmarterMail version 100.0.7593 or later installed, creating a backup including one or more subscriptions with mailboxes no longer fails with the “Unable to back up mail messages. Error: Failed to list mail messages” error. (PPPM-12454)
