This is a reminder that Joomla 3.x support has come to an end. We will be rolling out new stable releases for any plugins still needing them over the next few weeks that will completely remove Joomla 3.x support.
Each Joomla extension will be rewritten to modernized Joomla 6 extension structure. Joomla 4.x will be the new minimum going forward, but it is minimally supported. This means while extensions code wise maybe Joomla 4.x compatible and install on Joomla 4.x we will no longer be officially testing Joomla 4.x. Joomla 5.x and 6.x are both tested thoroughly.
In the future when CB Framework (in development) is complete and CB plugins are converted to standalone Joomla extensions we will be adopting a "last 2 major" policy. This means only the last 2 major releases of Joomla will be supported. So for example 6.x and 5.x only. This policy is already in effect for any new development. So for example new plugins will at most only support Joomla 5.x and 6.x.
This will allow us to improve the quality and performance of our plugins drastically as the minimum requirements for Joomla 3.x are simply impossible to support any longer. I apologize for those still on Joomla 3.x, but I strongly suggest at least migrating to 4.x, but ideally work your way up to 6.x ASAP.
I've updated our technical requirements documentation to reflect this information as well. If you've any questions regarding any of this please don't hesitate to ask.
