I’m not sure exactly what “this case” is, but op24 has some significant improvements/additions to the LuCI Network functions that would prevent (or at least hinder) my going back to op21. I’m stuck on 4.8.3 until there’s a 4.8.4 (op24) available.
I mean for the flint2, If you don’t need the glui you can use vanilla 25.12, It works fine.
I’m running 4.8.3 OP24 since november 2025 and never had a suggestion to upgrade to 4.8.4.
