Xdebug 3.6.0alpha1 is out!

This is a preview release that supports PHP 8.6 beta releases. It also contains rewritten code coverage support, for better results, and support for FrankenPHP workers.

On Windows, Xdebug will now fail faster when it attempts to a connect to a debugger IDE that is not listening at the start of a request, by disabling some odd Windows functionality. This should drastically speed up requests.

A few smaller features have been added as well, and a few bugs have been resolved.

Xdebug 3.6 no longer supports PHP 8.0 and PHP 8.1.

The full list of changes can be found on the updates page.

The source code can be found on the downloads page, and as usual, Xdebug is installable through PECL and PIE, and is also available as package for most Linux distributions.

If you find a bug, please file a report at Xdebug's Issue Tracker.

This release also contains a contribution by: Carlos Granados. Shivam Mathur, and Xavier Leune — Thanks!
