The project is happy to announce the release of Serendipity 2.6.0 as new stable version, featuring compatibility with PHP 8.4, some new features and many fixes.

Serendipity 2.6.0 is the first stable release of Serendipity that targets compatibility with PHP 8.4. Some additional highlights:

A better performing integrated cache
The ability to receive webmentions
Restored support for the gravatar mode in the gravatar plugin
The option to enable Two-Factor Authentication (with a code sent to your mail)
Elimination of a main source of timeouts in the backend, those that resulted in a warning about a missing referrer when writing for a long time on entries (on some server configurations)

These changes are just some of the collected improvement. There were also many internal optimization like an overdue upgrade of the jQuery version used in the backend, fixes to core themes like clean-blog and bootstrap4, solved pagination issues on less often used pages, and improvements to the thumbnail generation, to again mention only some of the features of the new version.

This release also contains security fixes for two recently reported security bugs that affect some server setups, so a timely upgrade is highly recommended.

Please see the release statement on GitHub for more (technical) details.

You can download the release file and unzip it to your installation as usual.
