Sourced from pytype's changelog.

Version 2021.11.24:

New features and updates:

• Update typeshed pin to commit 7cc5eb2 from Aug 8.
• Remove pytype's ability to accept python_version=3.
• Rename pytype "master" branch to "main".
• Remove the --gen-stub-imports flag. This was a no-op as of version 2021.11.18.
• Look up local names in nested class scopes when importing pyi files.
• Consistently use "base" instead of "parent" to refer to base classes. This changes the pickled representation of pytd.Class.

Bug fixes:

• Check for multiple module-level __getattr__ overloads.
• Raise a not supported error for constructors in type annotations in pyi files.
• Fix a [not-instantiable] false positive.
• Add a feature flag, --fix-module-collisions, to fix a 'duplicate top-level identifier' pyi issue.
• Don't enforce @​abstractmethod and @​coroutine consistency on properties.

Version 2021.11.18:

New features and updates:

• Enable --gen-stub-imports by default and make the flag a no-op. It will be removed in the next release.
• Pass more precise argument types to contextmanager exit methods.
• Add a helpful error message for use-after-delete.

Bug fixes:

• Recognize "/dev/null" as a package path in load_pytd.
• Remove references to the __builtin__ module.
• Allow disables for invalid calls in 3.9 to be put on the same lines as in 3.7.

Version 2021.11.12:

New features and updates:

• Use the official pyi files from attrs.
• Report a type error when comparing types (e.g. int > str) and when calling an overloaded comparison method like gt fails.
• Ship Linux AArch64 wheels.

Bug fixes:

• Use a homogeneous tuple as a pytd node sort key.
• Fix crash in pytd.Lookup caused by ClassType with unfilled cls pointer.
• Fix a pytd printer bug that was causing us to print 'Optional[import ...]'.
• Fix a pytype bug in matching Literal against Literal.
• Fix a bug in which classmethods weren't detected as protocol members.
• --use-enum-overlay:
  • Only add __new__ to an enum if it has members to lookup.
  • Skip potential enum members that are functions or have dunder names.
  • Teach the enum overlay what a descriptor is.
