Compare Source

Backwards-incompatible Changes

• Field aliases are now resolved before calling field_transformer, so transformers receive fully populated Attribute objects with usable alias values instead of None.
  The new Attribute.alias_is_default flag indicates whether the alias was auto-generated (True) or explicitly set by the user (False).
  #​1509

Changes

• Fix type annotations for attrs.validators.optional(), so it no longer rejects tuples with more than one validator.
  #​1496
• The attrs.validators.disabled() contextmanager can now be nested.
  #​1513
• Frozen classes can set on_setattr=attrs.setters.NO_OP in addition to None.
  #​1515
• It's now possible to pass attrs instances in addition to attrs classes to attrs.fields().

Because botus-receptus[sqlalchemy,uvloop] (25.6.1) @ git+https://github.com/bryanforbes/botus_receptus.git@v25.6.1 depends on attrs (^25.3.0)
 and erasmus depends on attrs (26.1.0), botus-receptus is forbidden.
So, because erasmus depends on botus_receptus[sqlalchemy,uvloop] (25.6.1) @ git+https://github.com/bryanforbes/botus_receptus.git@v25.6.1, version solving failed.
