+
+Multi-phase init extension modules may now indicate that they support
+running in subinterpreters that have their own GIL. This is done by using
+``Py_MOD_PER_INTERPRETER_GIL_SUPPORTED`` as the value for the
+``Py_mod_multiple_interpreters`` module def slot. Otherwise the module, by
+default, cannot be imported in such subinterpreters. (This does not affect
+the main interpreter or subinterpreters that do not have their own GIL.) In
+addition to the isolation that multi-phase init already normally requires,
+support for per-interpreter GIL involves one additional constraint:
+thread-safety. If the module has external (linked) dependencies and those
+libraries have any state that isn't thread-safe then the module must do the
+additional work to add thread-safety. This should be an uncommon case.

+
+The GIL is now (optionally) per-interpreter. This is the fundamental change
+for PEP 684. This is all made possible by virtue of the isolated state of
+each interpreter in the process. The behavior of the main interpreter
+remains unchanged. Likewise, interpreters created using
+``Py_NewInterpreter()`` are not affected. To get an interpreter with its
+own GIL, call ``Py_NewInterpreterFromConfig()``.

+slot. A value of ``0`` means the module does not support them. ``1`` means

+Implement :pep:`695`, adding syntactic support for generic classes, generic
+functions, and type aliases.
+
+A new ``type X = ...`` syntax is added for type aliases, which resolves at
+runtime to an instance of the new class ``typing.TypeAliasType``. The value
+is lazily evaluated and is accessible through the ``.__value__`` attribute.
+This is implemented as a new AST node ``ast.TypeAlias``.
+
+New syntax (``class X[T]: ...``, ``def func[T](): ...``) is added for
+defining generic functions and classes. This is implemented as a new
+``type_params`` attribute on the AST nodes for classes and functions. This
+node holds instances of the new AST classes ``ast.TypeVar``,
+``ast.ParamSpec``, and ``ast.TypeVarTuple``.
+
+``typing.TypeVar``, ``typing.ParamSpec``, ``typing.ParamSpecArgs``,
+``typing.ParamSpecKwargs``, ``typing.TypeVarTuple``, and ``typing.Generic``
+are now implemented in C rather than Python.
+
+There are new bytecode instructions ``LOAD_LOCALS``,
+``LOAD_CLASSDICT_OR_GLOBAL``, and ``LOAD_CLASSDICT_OR_DEREF`` to support
+correct resolution of names in class namespaces.
