Plesk Obsidian 18.0.64 is now available, with new updates and bug fixes. Below, we highlight some of the main improvements and features of the upgrade.
Panel and Hosting Improvements
Configure Plesk to use a smarthost for outgoing email from Plesk UI
Emails sent through a smarthost appear as though they originated from the smarthost IP address and are more likely to reach the intended recipient’s inbox if the smarthost has a good reputation. For this reason, we recommended using a reputable SMTP relay service as a smarthost, e.g. SendGrid, Mailgun, and Mailjet.
With Plesk Obsidian 18.0.64, it’s now possible to configure a smarthost or relayhost in Plesk on the server level. For more details, we have prepared a guide to configuring a smarthost or relayhost.
Website troubleshooting
In Plesk for Linux, the Website Log Check feature will be gradually rolled out to all Plesk Obsidian installations version 18.0.64 and later. This 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.
New support additions
MariaDB 11.4, the latest ‘long-term support’ version from the vendor, is now supported in Linux.
Furthermore, additional support for AlmaLinux 9 and for websocket traffic on Docker Proxy Rules have been added.
Further Improvements
The Plesk Repair feature in the UI can now fix MariaDB/MySQL server permissions. Plesk Obsidian 18.0.64 has also 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.
- A message has been added with general recommendations on action to take if there is insufficient disk space.
The new upgrade has also improved the Track Email Delivery feature in Websites & Domains > domain > “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
Furthermore, 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
Plesk Obsidian 18.0.64 has 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.
Additionally, the messages displayed when Plesk license limits are reached have been unified and updated. Messages about upgrading a Plesk license to a higher version are also now more helpful, clear, and informative.
The Node.js Toolkit now supports JavaScript modules (MJS files). It is also now possible to use the “Forgot password” feature via the CLI:
the
plesk bin admin --send-reset-link
command with the
-user or -email
generates a password reset link for the specified user, which will be sent via email.
Deployment Changes
The new Plesk upgrade ensures improved 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.
Additional Updates and Bug Fixes
Kaspersky AV removal
With the upgrade to Plesk Obsidian 18.0.64, Kaspersky Anti-Virus for Servers will be automatically removed from any servers it’s installed on. We recommend that you migrate to Sophos Anti-Virus for Servers, which is fully integrated with Plesk for both Linux and Windows, and also included in the Power Pack and Hosting Pack.
Upgrade to new ImunifyAV/AV+
The CloudLinux team have extended the Imunify360 extension with the improved ImunifyAV/AV+. The Imunify360 extension has also been renamed to Imunify.
Existing users of both 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.
Horde webmail to be removed
The Horde webmail has been deprecated and will be completely removed in April of 2025. For details and recommended actions, see the Feature and Deprecation Plan.
