v2.7.1

• When processing dataclass attributes, only do typing inference on collection types.
  Support for instantiating other typing types is left for the future, if desired.

  Closes #1129

• Fixed LookupMixIn missing from astroid.node_classes.

v2.7.0

• Import from astroid.node_classes and astroid.scoped_nodes has been deprecated in favor of
  astroid.nodes. Only the imports from astroid.nodes will work in astroid 3.0.0.

• Add support for arbitrary Enum subclass hierachies

  Closes pylint-dev/pylint#533
  Closes pylint-dev/pylint#2224
  Closes pylint-dev/pylint#2626

• Add inference tips for dataclass attributes, including dataclasses.field calls.
  Also add support for InitVar.

  Closes pylint-dev/pylint#2600
  Closes pylint-dev/pylint#2698
  Closes pylint-dev/pylint#3405
  Closes pylint-dev/pylint#3794

• Adds a brain that deals with dynamic import of IsolatedAsyncioTestCase class of the unittest module.

  Closes pylint-dev/pylint#4060

v2.6.6

• Added support to infer return type of typing.cast()

• Fix variable lookup's handling of exclusive statements

  Closes pylint-dev/pylint#3711

• Fix variable lookup's handling of function parameters

  Closes #180

• Fix variable lookup's handling of except clause variables

• Fix handling of classes with duplicated bases with the same name

  Closes #1088

v2.6.5

• Fix a crash when there would be a 'TypeError object does not support
  item assignment' in the code we parse.

  Closes pylint-dev/pylint#4439

• Fix a crash when a AttributeInferenceError was raised when
  failing to find the real name in infer_import_from.

  Closes pylint-dev/pylint#4692

v2.6.4

• Fix a crash when a StopIteration was raised when inferring
  a faulty function in a context manager.

  Closes pylint-dev/pylint#4723

v2.6.3

• Added If.is_sys_guard and If.is_typing_guard helper methods

• Fix a bad inferenece type for yield values inside of a derived class.

  Closes #1090

• Fix a crash when the node is a 'Module' in the brain builtin inference

  Closes pylint-dev/pylint#4671

• Fix issues when inferring match variables

  Closes pylint-dev/pylint#4685

• Fix lookup for nested non-function scopes

• Fix issue that TypedDict instance wasn't callable.

  Closes pylint-dev/pylint#4715

• Add dependency on setuptools and a guard to prevent related exceptions.

v2.6.2

• Fix a crash when the inference of the length of a node failed

  Closes pylint-dev/pylint#4633

• Fix unhandled StopIteration during inference, following the implementation
  of PEP479 in python 3.7+

  Closes pylint-dev/pylint#4631
  Closes #1080

v2.6.1

• Fix issue with TypedDict for Python 3.9+

  Closes pylint-dev/pylint#4610

v2.6.0

• Appveyor and travis are no longer used in the continuous integration

• setuptools_scm has been removed and replaced by tbump in order to not
  have hidden runtime dependencies to setuptools

• NodeNg, the base node class, is now accessible from astroid or
  astroid.nodes as it can be used for typing.

• Update enum brain to improve inference of .name and .value dynamic class
  attributes

  Closes pylint-dev/pylint#1932
  Closes pylint-dev/pylint#2062
  Closes pylint-dev/pylint#2306

• Removed Repr, Exec, and Print nodes as the ast nodes
  they represented have been removed with the change to Python 3

• Deprecate Ellipsis node. It will be removed with the next minor release.
  Checkers that already support Python 3.8+ work without issues. It's only
  necessary to remove all references to the astroid.Ellipsis node.
  This changes will make development of checkers easier as the resulting tree for Ellipsis
  will no longer depend on the python version. Background: With Python 3.8 the
  ast.Ellipsis node, along with ast.Str, ast.Bytes, ast.Num,
  and ast.NamedConstant were merged into ast.Constant.

• Deprecated Index and ExtSlice nodes. They will be removed with the
  next minor release. Both are now part of the Subscript node.
  Checkers that already support Python 3.9+ work without issues.
  It's only necessary to remove all references to the astroid.Index and
  astroid.ExtSlice nodes. This change will make development of checkers
  easier as the resulting tree for ast.Subscript nodes will no longer
  depend on the python version. Background: With Python 3.9 ast.Index
  and ast.ExtSlice were merged into the ast.Subscript node.

• Updated all Match nodes to be internally consistent.

• Add Pattern base class.
