Changelog

Sourced from attrs's changelog.

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. #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

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.

  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

Changes

• Updated attr.validators.__all__ to include new validators added in #425. #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
• When collecting attributes using @attr.s(auto_attribs=True), attributes with a default of None are now deleted too. #523, #556
• Fixed attr.validators.deep_iterable() and attr.validators.deep_mapping() type stubs. #533
• attr.validators.is_callable() validator now raises an exception attr.exceptions.NotCallableError, a subclass of TypeError, informing the received value. #536
• @attr.s(auto_exc=True) now generates classes that are hashable by ID, as the documentation always claimed it would. #543, #563
• Added attr.validators.matches_re() that checks string attributes whether they match a regular expression. #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
• The fake filename for generated methods is now more stable. It won't change when you restart the process. #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
• 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 on how to use it. #580
