It was a long and tedious process on php 8.1 where I first updated Seblod and suitable plugins to the latest Seblod 3, cleaned up all the requirements to upgrade to J 4.4.2 and then after that I installed Seblod 4.3.0 (first run) before updating to J 4.4.2.
Don't forget that MANY plugins from Seblod require a different version between the latest Seblod 3 and Seblod 4 !!! At the bottom of each plugin page you will find the different versions you need for either Seblod 3 or 4 !!!
Yes, during last year I have updated all of my sites including those ones with seblod, and really it has been a very tedious process, as you said.
But my question is more simple, I have Joomla 4.4.1 and just want to know if Seblod 4.3.0 (well, now is 4.3.1) is compatible up to Joomla 4.2.2, because I don't want to update the sites under production and break them partially as has happened other times.
On seblod.com still says that it is compatible only up to Joomla version 4.4.1, and not 4.4.2 who was out one month ago.
