Nixpkgs 25.11: Further Backward Incompatibilities and Package Updates

Haskell packages usually only need to depend on an LLVM version matching GHC if they force the use the LLVM backend even if NCG is available. In this case, it is best to use the `forceLlvmCodegenBackend` helper. In all other cases, like linking against `libLLVM`, Haskell packages should use the appropriate version of `llvmPackages` from `pkgs`. - `uw-ttyp0` has been updated to version 2.1. The filenames of the OTB and PSF fonts have been changed to match the upstream naming convention. If you were loading a font by path, for example in the `console.font` NixOS option, remember to update the filename accordingly. - `base16-builder` node package has been removed due to lack of upstream maintenance. - `python3Packages.bjoern` has been removed, as the upstream is unmaintained and it depends on a 14-year-old version of http-parser with numerous vulnerabilities. - `buildGoModule` now warns if `<pkg>.passthru.overrideModAttrs` is lost during the overriding of its result packages. - `gentium` package now provides `Gentium-*.ttf` files, and not `GentiumPlus-*.ttf` files like before. The font identifiers `Gentium Plus*` are available in the `gentium-plus` package, and if you want to use the more recently updated package `gentium` [by sil](https://software.sil.org/gentium/), you should update your configuration files to use the `Gentium` font identifier. - `space-orbit` package has been removed due to lack of upstream maintenance. Debian upstream stopped tracking it in 2011. - Derivations setting both `separateDebugInfo` and one of `allowedReferences`, `allowedRequisites`, `disallowedReferences` or `disallowedRequisites` must now set `__structuredAttrs` to `true`. The effect of reference whitelisting or blacklisting will be disabled on the `debug` output created by `separateDebugInfo`. - `victoriametrics` no longer contains VictoriaLogs components. These have been separated into the new package `victorialogs`. - `mx-puppet-discord` was removed from Nixpkgs along with its NixOS module as it was unmaintained and was the only user of sha1 hashes in tree. - `kbd` package's `outputs` now include a `man` and `scripts` outputs. The `unicode_start` and `unicode_stop` Bash scripts are now part of the `scripts` output, allowing most usages of the `kbd` package to not pull in `bash`. - `spidermonkey_91` has been removed, as it has been EOL since September 2022. - `hiawata` has been removed, due to lack of active development upstream, lack of maintainership downstream and upcoming security issues. - `cudaPackages.cudatoolkit-legacy-runfile` has been removed. - `conduwuit` was removed due to upstream ceasing development and deleting their repository. For existing data, a migration to `matrix-conduit`, `matrix-continuwuity` or `matrix-tuwunel` may be possible. - The `ghcInfo` and `controlPhases` functions have been removed from `haskell.lib.compose` and `haskell.lib`. They were unused and would return incorrect results. - Instead of using `controlPhases`, the `doCheck` attribute of derivations can be accessed which is more accurate. `doBenchmark` can't be introspected at the moment. - To detect cross compilation, the relevant platforms exposed by `stdenv` should be compared instead of using `ghcInfo`. - Nixpkgs no longer packages any `ghcjs` compiler. - To find a suitable `nativeGhc`, `buildHaskellPackages` should be used. `ghcInfo` would use `ghc.bootPkgs.ghc` if cross compiling, and the given `ghc` otherwise. This approach is not recommended since it results in mismatched GHC versions. - `gnome-keyring` no longer ships with an SSH agent anymore because it has been deprecated upstream. You should use `gcr_4` instead, which provides the same features. More information on why this was done can be found on [the relevant GCR upstream PR](https://gitlab.gnome.org/GNOME/gcr/-/merge_requests/67). - `python3Full` and its versioned attributes (python3xxFull) have been removed. Bluetooth support is now enabled in the default python3 attributes. The X11 support built the tkinter module, which is available as a dedicated attribute on the package set.

This section continues detailing backward incompatibilities in Nixpkgs 25.11. Key changes include guidance on Haskell packages' LLVM dependencies, updates to font package filenames (`uw-ttyp0`, `gentium`), and the removal of numerous unmaintained or end-of-life packages such as `base16-builder`, `python3Packages.bjoern`, `space-orbit`, `spidermonkey_91`, `hiawata`, `conduwuit`, and `mx-puppet-discord`. `victoriametrics` components have been separated into `victorialogs`, and `kbd` now provides `man` and `scripts` outputs. `ghcInfo` and `controlPhases` functions have been removed from Haskell libraries with alternative usage instructions provided. `gnome-keyring` no longer includes an SSH agent (recommending `gcr_4`), and `python3Full` attributes have been removed, with Bluetooth support integrated into default `python3`.
