The only way the community would collectively update their extension is to release the build, but obviously fix the major importance things for the framework for completion. With Symfony they continue with their major version cycle, and just left the bundle makers behind. To put into context, Symfony major (LTS) version v5.4 to v7.4 is a 2 year gap. Flarum v1.0.0 is currently at 4 year gap, lots of extension were made during that time. Eventually time will get people together and patch/fix their code for Flarum v2.0, looking at the Flarum Extensions website, we are a long way to get the same level of extensions available.
Flarum 2.0 Beta 3
- 44 extension (Should be 45, the LDAP extension doesn't appear)
Flarum 2.0 Beta 2
Flarum 2.0 Beta 1
Flarum 1.8.10
I'm in the process of wanting to use Flarum 2.0 too, and then patch the extensions I need running again.
