The latest release (3.3.12) is now available on the “Downloads” page.
You can read the full list of changes on the “Changes” page. But, briefly, the major part of this update has been making kiwitrees compatible with PHP 8.2. All previously reported related issues have been fixed, and no new ones reported for some months.
One small new feature has been added – a “floating” message or contact icon has been added. It requires a module to be enabled in the administration area, but nothing more. It can be used with ot instead of any other contact or message link.
