Plesk

Plesk Obsidian 18.0.79 is here, with security at the heart of this release. Following a comprehensive security audit, we addressed multiple vulnerabilities and introduced additional hardening improvements across the platform. Beyond security, this release expands the capabilities of the Plesk REST API, adds support for Microsoft SQL Server 2025, and delivers a wide range of stability, compatibility, and usability improvements for Linux and Windows servers.

Plesk Obsidian 18.0.78 introduces smarter SSL/TLS defaults that help secure newly deployed servers automatically and gives administrators more flexibility when using multi-factor authentication. This update also improves the GoAccess experience, and delivers a broad range of stability, compatibility, and security improvements across Linux and Windows.

summary Plesk comes with a mail server used to provide email services for mailboxes and mailing lists. After Plesk installation, the mail server is configured automatically using default settings. You may want to review them to make sure that they satisfy your needs. In this topic, you will learn how to configure a number of server-wide mail settings, such as relaying options or the maximum number of outgoing emails an individual mailbox can send per day.

The European Accessibility Act (EAA) establishes accessibility requirements for a wide range of digital products and services across the EU. After reviewing the act, we identified WCAG 2.1 AA as the technical standard that addresses its requirements and have been using it as our benchmark for improvements to the Plesk platform.

We are excited to announce the latest release of Plesk Obsidian: v18.0.77. This update brings one of the most significant accessibility improvements in recent Plesk history, introduces native ACME protocol support with the new ACME SSL extension, adds support for the GoAccess web statistics tool, and delivers a wide range of fixes, platform updates, and security improvements across Linux and Windows.

At Plesk, we’re committed to providing you with a fast, secure platform that evolves with today’s standards. That’s why, over the coming releases of Plesk Obsidian, we will begin transitioning away from legacy web statistics tools and introducing a more modern default. These updates simplify long‑term maintenance and ensure continued compatibility with the latest operating systems. Here’s what’s changing, and what it means for you.

Plesk Obsidian 18.0.76 has arrived, bringing a fresh set of improvements designed to upgrade your hosting experience.

It introduces smarter mail routing, easier database upgrades, better accessibility, and a wide range of stability fixes that help keep servers running smoothly.

Upgrading PHP on existing websites isn’t always straightforward. The benefits must be weighed against the risks and expenses of legacy applications, custom code, and third-party integrations. However, running end-of-life PHP versions without security patches exposes your environments to serious risks, with hundreds of unpatched vulnerabilities prevalent in old PHP versions – dozens of which are critical. That’s where Extended Lifecycle Support (ELS) for PHP comes in.

We’re excited to introduce Plesk Obsidian 18.0.75, the first Plesk release of 2025! This release highlights stronger SSL/TLS management, expanded development stack support, improved accessibility, and a range of stability fixes dedicated on making server management smoother than ever. Here’s a closer look at what this update brings.
