 ## [`8.1.1` (2026-06-24)](https://github.com/kdeldycke/click-extra/compare/v8.1.0...v8.1.1)
 
 - Fix `multiple` and variadic (`nargs=-1`) options typed with `EnumChoice`: their tuple default was stringified as a whole (`str((MyEnum.FOO,))`) instead of per member, so the default tripped Click's `Value must be an iterable` check when the option was left unset.
-- Fix `decorator_factory` leaking options across uses of a pre-instantiated decorator: when `command()` is stored (e.g. in a pytest parametrize list) and reused, Click mutated the shared `params` list by extending it with each decorated function's options, adding duplicates on every reuse. The fix re-evaluates `params_func()` fresh on each application.
+- Fix `decorator_factory` leaking options across reuses of a pre-instantiated decorator: applying the same `command()` or `group()` decorator to several functions accumulated duplicate parameters, because Click extended its shared `params` list in place on each use.
