Been using 3.0 for some time. Thought I would try 3.1 for a new project. First attempt at an extension karma ext comes up with the following:
The “phpbb/karma” extension is not valid.
Meta field type is invalid.
1) is 3.1... preferable to 3.0...
2nd) Having launched the site with 20 users in first day, how easy would it be to migrate database back to 3.0 ...
