Version 2.9.6.1 of AFWall+ has been released about two weeks ago but is still not available in the F-Droid repo (2.9.6 is the latest build in F-Droid). No problems have been noted in the F-Droid wiki: https://f-droid.org/wiki/page/dev.ukanth.ufirewall
I have also asked about this at AFWall’s issue tracker: Latest version not available as APK/F-Droid? · Issue #744 · ukanth/afwall · GitHub
