- the `xorg` package set has been deprecated, packages have moved to the top level.
-`python3Packages.buildPythonPackage` and `python3Packages.buildPythonApplication` now throw errors in the presence of `pytestFlagsArray`.
Please use [`pytestFlags` and `(enabled|disabled)(TestPaths|Tests|TestMarks)`](#using-pytestcheckhook) instead.
If modifying the Nix expression is not feasible, users can remediate the error by overriding `pytestFlagsArray` with `null` or `[ ]`.
-`python3Packages.pygame` has been been renamed to `python3Packages.pygame-original`, the attribute `python3Packages.pygame` will from python 3.14 default to the more actively maintained `python3Packages.pygame-ce`
-`fastly` has been updated to major version 14. For more information, you can check the [release notes](https://github.com/fastly/cli/releases/tag/v14.0.0)
