What's New in astroid 3.0.0?

Release date: 2023-09-25

• Add support for Python 3.12, including PEP 695 type parameter syntax.

  Closes #2201

• Remove support for Python 3.7.

  Refs #2137

• Use the global inference cache when inferring, even without an explicit InferenceContext. This is a significant performance improvement given how often methods default to None for the context argument. (Linting astroid itself now takes ~5% less time on Python 3.12; other projects requiring more complex inference calculations will see greater speedups.)

  Refs #529

• Following a deprecation period starting in astroid 2.7.0, the astroid.node_classes and astroid.scoped_nodes modules have been removed in favor of astroid.nodes.node_classes and astroid.nodes.scoped_nodes.

  Closes #1072

• Following a deprecation period starting in astroid 2.12.0, the astroid.mixins module has been removed in favor of astroid.nodes._base_nodes (private).

  Refs #1633

• Return all existing arguments when calling Arguments.arguments(). This also means find_argname will now use the whole list of arguments for its search.

  Closes #2213

• Exclude class attributes from the __members__ container of an Enum class when they are nodes.AnnAssign nodes with no assigned value.

  Refs pylint-dev/pylint#7402

• Remove @cached and @cachedproperty decorator (just use @cached_property from the stdlib).

  Closes #1780 Refs #2140

• Remove the inference module. Node inference methods are now in the module defining the node, rather than being associated to the node afterward.

  Closes #679
