 %changelog
+* Wed Oct 29 2025 lichenguang <lichenguang@kylinos.cn> 25.4.0-1
+- Update to 25.4.0
+- Drop support for Python 3.8.
+- Add support for Namespace Packages:
+- * Support implicit native namespace packages (PEP 420). Get rid of the error: Source directory lacks __init__.py.
+- * Some limited support for legacy namespace packages is included as well (with declare_namespace(__name__) or __path__ = extend_path(__path__, __name__)).
+- * Better messages are now triggered when there is a module/package name collision (exit code will not change though).
+- Signatures of function definitions are now wrapped onto several lines when the function has the focus.
+- The first parameter of classmethods and methods (cls or self) is colored in gray so it's clear that these are not part of the API.
+- When pydoctor encounters an invalid signature, it shows (…) as the signature instead of the misleading zero argument signature.
+- Improve field tables so the correspondence with the description column is more legible.
+- Highlighting in readthedocs theme now cover the whole docstring content instead of just the signature.
+- Fix a bug in the MRO computing code that would result in an incorrect Cannot compute linearization of the class inheritance hierarchy message for valid types extending typing.Generic as well as other generic classes.
