The following APS applications will be deprecated and removed from the Plesk APS catalog in Plesk Obsidian 18.0.71: DotNetNuke, Magento, ZenCart, concrete5, PhpList, osCommerce, gallery, bbclone, SugarCRM, Coppermine, and Squirrelmail.

Once the APS applications from this list have been deprecated, they will no longer be available for installation from the APS catalog. Already installed applications will not be affected. You would still be able to install applications from the list using their official installation documentation.

In Plesk for Windows, we plan to replace the auto-reply function developed by Plesk with the native solutions provided by the supported mail servers. This will improve mail deliverability, but also cause some UX changes:

• If MailEnable is used as the mail server, users will still be able to configure auto-reply in the Plesk interface, although some currently existing settings may no longer be available. The already configured auto-reply settings supported by MailEnable will be automatically migrated to MailEnable when updating to Plesk Obsidian 18.0.69.
• If SmarterMail is used as the mail server, users will need to configure auto-reply using the SmarterMail Webmail interface, same way as the Remote SmarterMail users are already doing. For Remote SmarterMail users, nothing is going to change.
• If IceWarp is used as the mail server, users will no longer be able to configure auto-reply in the Plesk interface.

• To replace RKHunter, use a different solution. For example, the free version of the Imunify extension comes with a fully-featured malware file scanner, and also reputation and blacklist status monitoring.
• To view statistics, use the Monitoring extension.

Use the new Imunify extension, which includes ImunifyAV functionality.

No action is required. The ability to keep using the legacy UI will be removed in Docker 2.1.0.

Switch to another webmail software supported in Plesk.

Purchase a Premium Antivirus for Servers license.

• Switch to Sophos Anti-Virus for Servers.
• If you use the Hosting Pack or the Power Pack version 2023 or older, you need to update the pack first, and then switch to Sophos Anti-Virus for Servers.

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’ll need to add the --header "Content-Type: application/json" option to such commands to keep them working correctly.

Use the Multi-Factor Authentication (MFA) extension installed in Plesk by default. Multi-Factor Authentication (MFA) offers all features previously available in the Google Authenticator extension and much more.

Use the Log Browser extension installed in Plesk by default. Log Browser offers all features previously available in the Action Log extension and much more.

Switch to Dynamic List view manually in advance. You can also switch all your customers to Dynamic List view at once by adding the following lines to the panel.ini file:

[navigation]

forceWebsiteList = dynamic

hideWebsiteList = active

Use Microsoft DNS.

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.

The following SDK functionality will be deprecated and removed in Plesk Obsidian 18.0.57. These are legacy functions and classes exposed in the pm.php file:

• Functions: pm_alert(), pm_warning(), pm_comm_button(), pm_get_gpc(), pm_isset_gpc(), pm_set_gpc(), pm_get_locale(), pm_go_to(), pm_go_to_uplevel(), pm_ldate(), pm_ltime(), pm_ldatetime(), pm_link_button(), pm_lmsg(), pm_plesk_mail(), pm_psaerror(), pm_safetyhtml(), pm_size_b_printing(), pm_size_kb_printing(), pm_size_mb_printing(), pm_size_pretty_printing(), pm_topnote(), pm_util_exec(), pm_util_io_exec().
• Classes: pm_errHandler, pm_Checker, pm_cList, pm_Form, pm_CustomButton, pm_CustomButtonManager.

We would like to make the following recommendations:

• If you have Plesk extensions published in the Plesk Extension Catalog, then we have already checked that the extensions do not use those legacy functions and classes.
• If you have Plesk extensions not published in the Plesk Extension Catalog, check if your extensions use the modern SDK.
