Changelog

*Sourced from [attrs's changelog](https://github.com/python-attrs/attrs/blob/master/CHANGELOG.rst).* > 19.3.0 (2019-10-15) > =================== > > Changes > ------- > > - Fixed `auto_attribs` usage when default values cannot be compared directly with `==`, such as `numpy` arrays. [\#585](https://github-redirect.dependabot.com/python-attrs/attrs/issues/585) > > ------------------------------------------------------------------------ > > 19.2.0 (2019-10-01) > =================== > > Backward-incompatible Changes > ----------------------------- > > - Removed deprecated `Attribute` attribute `convert` per scheduled removal on 2019/1. This planned deprecation is tracked in issue [\#307](https://github-redirect.dependabot.com/python-attrs/attrs/issues/307). [\#504](https://github-redirect.dependabot.com/python-attrs/attrs/issues/504) > - `__lt__`, `__le__`, `__gt__`, and `__ge__` do not consider subclasses comparable anymore. > > This has been deprecated since 18.2.0 and was raising a `DeprecationWarning` for over a year. [\#570](https://github-redirect.dependabot.com/python-attrs/attrs/issues/570) > > Deprecations > ------------ > > - The `cmp` argument to `attr.s()` and `attr.ib()` is now deprecated. > > Please use `eq` to add equality methods (`__eq__` and `__ne__`) and `order` to add ordering methods (`__lt__`, `__le__`, `__gt__`, and `__ge__`) instead – just like with [dataclasses](https://docs.python.org/3/library/dataclasses.html). > > Both are effectively `True` by default but it's enough to set `eq=False` to disable both at once. Passing `eq=False, order=True` explicitly will raise a `ValueError` though. > > Since this is arguably a deeper backward-compatibility break, it will have an extended deprecation period until 2021-06-01. After that day, the `cmp` argument will be removed. > > `attr.Attribute` also isn't orderable anymore. [\#574](https://github-redirect.dependabot.com/python-attrs/attrs/issues/574) > > Changes > ------- > > - Updated `attr.validators.__all__` to include new validators added in [\#425](). [\#517](https://github-redirect.dependabot.com/python-attrs/attrs/issues/517) > - Slotted classes now use a pure Python mechanism to rewrite the `__class__` cell when rebuilding the class, so `super()` works even on environments where `ctypes` is not installed. [\#522](https://github-redirect.dependabot.com/python-attrs/attrs/issues/522) > - When collecting attributes using `@attr.s(auto_attribs=True)`, attributes with a default of `None` are now deleted too. [\#523](https://github-redirect.dependabot.com/python-attrs/attrs/issues/523), [\#556](https://github-redirect.dependabot.com/python-attrs/attrs/issues/556) > - Fixed `attr.validators.deep_iterable()` and `attr.validators.deep_mapping()` type stubs. [\#533](https://github-redirect.dependabot.com/python-attrs/attrs/issues/533) > - `attr.validators.is_callable()` validator now raises an exception `attr.exceptions.NotCallableError`, a subclass of `TypeError`, informing the received value. [\#536](https://github-redirect.dependabot.com/python-attrs/attrs/issues/536) > - `@attr.s(auto_exc=True)` now generates classes that are hashable by ID, as the documentation always claimed it would. [\#543](https://github-redirect.dependabot.com/python-attrs/attrs/issues/543), [\#563](https://github-redirect.dependabot.com/python-attrs/attrs/issues/563) > - Added `attr.validators.matches_re()` that checks string attributes whether they match a regular expression. [\#552](https://github-redirect.dependabot.com/python-attrs/attrs/issues/552) > - Keyword-only attributes (`kw_only=True`) and attributes that are excluded from the `attrs`'s `__init__` (`init=False`) now can appear before mandatory attributes. [\#559](https://github-redirect.dependabot.com/python-attrs/attrs/issues/559) > - The fake filename for generated methods is now more stable. It won't change when you restart the process. [\#560](https://github-redirect.dependabot.com/python-attrs/attrs/issues/560) > - The value passed to `@attr.ib(repr=…)` can now be either a boolean (as before) or a callable. That callable must return a string and is then used for formatting the attribute by the generated `__repr__()` method. [\#568](https://github-redirect.dependabot.com/python-attrs/attrs/issues/568) > - Added `attr.__version_info__` that can be used to reliably check the version of `attrs` and write forward- and backward-compatible code. Please check out the [section on deprecated APIs](http://www.attrs.org/en/stable/api.html#deprecated-apis) on how to use it.
