sellout	I thought I had just put `Cabal = hfinal.Cabal_3_10_3_0` and same for `Cabal-syntax` in an overlay, then set it in `custom-setup` in the Cabal file … but cabal2nix doesn’t care about the `custom-setup`, so there must have been a third piece.	15:25:02
sellout	Actually, I think this is right – the issue I was just running into was because I set a flag in `configureFlags` rather than passing it to `callCabal2NixWithOptions` (which only mattered because there are `build-depends` conditionalized by the flag).	17:53:14
Lenny.	heyo, a dependency I use got marked broken in 25.11 and is still broken on master. It looks like there is a fix out here https://github.com/dustin/mqtt-hs/commit/211d5742df9295f75f04ad58a51e6c42f1320515 Do the packages from hackage get updated automatically, or should I open a PR that does something similar to https://github.com/NixOS/nixpkgs/pull/470484/files?	19:04:31
nf	Oh well, I suppose the package should be fixed to work with recent versions anyway.	19:05:42
