This is a 2.4.20 stable release with improved PHP 8 compatibility and a couple of usability and security bugfixes.
Therefore please consider urgent upgrade of your installation to this version, to keep your FA instances safe.
This is especially important in not fully trusted environments like publicly accessible installations (demos or other installations accessibly by not fully trusted users).

This release fixes some problems on php versions 8.2 to 8.4. The following versions has been tested: 8.0.0, 8.0.7, 8.0.12, 8.1.6, 8.2.0, 8.3.2, 8.4.13 and 8.5.5.

Security

FrontAccounting should NOT be used via unsecure http protocol. If you really need this - change SECURE_ONLY constant in /includes/session.inc to false (comment in the file added).
