[#&#8203;988](https://togithub.com/python-attrs/attrs/issues/988) ##### Deprecations - Python 3.6 is now deprecated and support will be removed in the next release. [#&#8203;1017](https://togithub.com/python-attrs/attrs/issues/1017) ##### Changes - `attrs.field()` now supports an *alias* option for explicit `__init__` argument names. Get `__init__` signatures matching any taste, peculiar or plain! The [PEP 681 compatible](https://peps.python.org/pep-0681/#field-specifier-parameters) *alias* option can be use to override private attribute name mangling, or add other arbitrary field argument name overrides. [#&#8203;950](https://togithub.com/python-attrs/attrs/issues/950) - `attrs.NOTHING` is now an enum value, making it possible to use with e.g. [`typing.Literal`](https://docs.python.org/3/library/typing.html#typing.Literal). [#&#8203;983](https://togithub.com/python-attrs/attrs/issues/983) - Added missing re-import of `attr.AttrsInstance` to the `attrs` namespace. [#&#8203;987](https://togithub.com/python-attrs/attrs/issues/987) - Fix slight performance regression in classes with custom `__setattr__` and speedup even more. [#&#8203;991](https://togithub.com/python-attrs/attrs/issues/991) - Class-creation performance improvements by switching performance-sensitive templating operations to f-strings. You can expect an improvement of about 5% -- even for very simple classes. [#&#8203;995](https://togithub.com/python-attrs/attrs/issues/995) - `attrs.has()` is now a [`TypeGuard`](https://docs.python.org/3/library/typing.html#typing.TypeGuard) for `AttrsInstance`. That means that type checkers know a class is an instance of an `attrs` class if you check it using `attrs.has()` (or `attr.has()`) first. [#&#8203;997](https://togithub.com/python-attrs/attrs/issues/997) - Made `attrs.AttrsInstance` stub available at runtime and fixed type errors related to the usage of `attrs.AttrsInstance` in *Pyright*. [#&#8203;999](https://togithub.com/python-attrs/attrs/issues/999) - On Python 3.10 and later, call [`abc.update_abstractmethods()`](https://docs.python.org/3/library/abc.html#abc.update_abstractmethods) on dict classes after creation. This improves the detection of abstractness. [#&#8203;1001](https://togithub.com/python-attrs/attrs/issues/1001) - *attrs*'s pickling methods now use dicts instead of tuples. That is safer and more robust across different versions of a class. [#&#8203;1009](https://togithub.com/python-attrs/attrs/issues/1009) - Added `attrs.validators.not_(wrapped_validator)` to logically invert *wrapped_validator* by accepting only values where *wrapped_validator* rejects the value with a `ValueError` or `TypeError` (by default, exception types configurable). [#&#8203;1010](https://togithub.com/python-attrs/attrs/issues/1010) - The type stubs for `attrs.cmp_using()` now have default values. [#&#8203;1027](https://togithub.com/python-attrs/attrs/issues/1027) - To conform with [PEP 681](https://peps.python.org/pep-0681/), `attr.s()` and `attrs.define()` now accept *unsafe_hash* in addition to *hash*. [#&#8203;1065](https://togithub.com/python-attrs/attrs/issues/1065) </details> --- ### Configuration 📅 **Schedule**: Branch creation - "every weekend" in timezone Etc/UTC, Automerge - "after 1 am and before 7 am" in timezone Etc/UTC. 🚦 **Automerge**: Disabled by config.
