Release notes

Sourced from cattrs's releases.

v26.1.0

• Add the tomllib preconf converter. See here for details. (#716)
• Customizing un/structuring of attrs classes, dataclasses, TypedDicts and dict NamedTuples is now possible by using Annotated[T, override()] on fields. See here for more details. (#717)
• Fix structuring of nested generic classes with stringified annotations. (#688)
• Python 3.9 is no longer supported, as it is end-of-life. Use previous versions on this Python version. (#698)
• Apply the attrs converter to the default value before checking if it is equal to the attribute's value, when omit_if_default is true and an attrs converter is specified. (#696)
• Use the optional _value_ type hint to structure and unstructure enums if present. (#699)
• Aliases (when in use) now properly generate rename metadata in generated hooks. (#706 #710)
• cattrs now tracks performance using codspeed. (#703)
• The tomlkit preconf converter now properly handles native date objects when structuring. (#707 #708)
• The tomlkit preconf converter now passes date objects directly to tomlkit for unstructuring. (#707 #708)
• Enum handling has been optimized by switching to hook factories, improving performance especially for plain enums. (#705)
• Fix cattrs.strategies.include_subclasses when used with cattrs.strategies.configure_tagged_union and classes using diamond inheritance. (#685 #713)
• Fix cattrs.strategies.configure_tagged_union when used with recursive type aliases. (#678 #714)
