Plesk administrators should review the latest Obsidian maintenance releases as part of a regular server security routine. The official Plesk change log lists Obsidian 18.0.80 Update 3 and 18.0.79 Update 7 on 14 August 2026, with critical security fixes and continuing improvements across the platform.

What is included in the latest Plesk maintenance work?

The recent Plesk maintenance stream focuses on security fixes, third-party component updates, and stability improvements. The change log also lists improvements for DNS record transfer, ClamAV installation, mailbox security permissions, SSL configuration, monitoring, and extension maintenance.

Plesk security checklist for administrators

• Run a supported Plesk Obsidian version and apply the latest available microupdates.
• Review extension updates for Firewall, SSL It, Lets Encrypt, Monitoring, and email security.
• Confirm that server operating systems and database packages remain within their supported lifecycle.
• Test backups, DNS changes, mailbox delivery, TLS settings, and customer access after maintenance.
• Remove unsupported legacy Plesk versions from production or plan a controlled migration.

Why supported versions matter

Panel security depends on the entire stack: the operating system, web server, mail services, extensions, and the panel itself. Staying current reduces exposure to known issues and keeps vendor fixes available when a new vulnerability is disclosed.

Review the official Plesk Obsidian change log for release-specific details. For upgrades, hardening, migration, or ongoing panel administration, professional Plesk support can help keep production changes controlled and documented.
