Comment 2 Gwyn Ciesla 2023-12-26 19:27:39 UTC
3.4.0 is coming to f39. f38 has 3.1.0 and backporting appears non-trivial.

Comment 3 Paul Howarth 2024-01-02 09:00:14 UTC
Looking at the changelog, I don't see any backwards-incompatible changes between 3.1.0 and 3.4.0 so I think it should be OK to update f38 to 3.4.0.
