Introducing Plesk Obsidian 18.0.76: Accessibility Improvements and Smarter Mail Routing
Plesk Obsidian 18.0.76 has arrived, bringing a fresh set of improvements designed to upgrade your hosting experience.
This release gives administrators more control, streamlining maintenance tasks and continuing to improve usability across the platform. It introduces smarter mail routing, easier database upgrades, better accessibility, and a wide range of stability fixes that help keep servers running smoothly.
Highlights of the Release
Resolved: Security Issue on Linux Systems
This update addresses a critical security issue on Linux systems. We strongly recommend that you apply it as soon as possible.
Smarter Mail Routing with Per-Domain Smarthost Support
Administrators now have native Smarthost support per domain for Linux and Windows, available directly in the Mail Settings interface. This feature is supported across:
- Postfix on Linux.
- MailEnable and SmarterMail on Windows.
For hosting providers and administrators managing multiple domains with different mail delivery requirements, this provides significantly more flexibility and control.
Simplified MariaDB Upgrades
Upgrade support to MariaDB 11.8 is now available directly from the Plesk interface on supported Linux servers. This upgrade is exclusive to Linux systems, excluding ELS and CloudLinux environments.
Continued Accessibility Improvements
Improved accessibility remains a key priority for Plesk. In this release, several core pages and extensions have been improved to provide a more inclusive and usable experience.
Enhancements include:
- Improved UI scalability across Plesk core and extensions, supporting up to 200% browser zoom.
- Improved accessibility of the Action Log Settings in the Log Browser extension.
- Certain Plesk extensions now include text descriptions for non‑text elements.
- Improved accessibility of Plesk module extensions by fixing non‑semantic HTML and missing ARIA roles.
Feature Improvements
- Support has been implemented in the TuxCare PHP extension (CLI) to install TuxCare ELS PHP versions without the corresponding base Plesk PHP version.
- Plesk for Linux now supports ImageMagick 7 for PHP 8.5.
Deprecations and Stability Improvements
Deprecations
Due to the deprecation notice from the AWStats vendor, we will remove AWStats from the product distribution in Plesk Obsidian 18.0.79.
We recommend switching to the alternative tool available in the product.
Stability Improvements Across the Platform
Alongside these feature improvements, this release delivers a wide range of fixes that improve reliability across Plesk components and extensions.
Several issues affecting Backup Manager, Laravel Toolkit, Joomla Toolkit, and email services have been resolved. Mail reliability has also been improved through fixes related to DKIM signing, DMARC reporting, and mail configuration repairs.
On Linux systems, improvements include:
- Better Fail2Ban compatibility.
- Improved sendmail wrapper logging by printing the invocation context to the log.
- More accurate diagnostics reporting.
- Issue resolved where Plesk did not send password reset emails from the login page.
