gh-103763: Implement PEP 695 ( #103764 )
...
This implements PEP 695, Type Parameter Syntax. It adds support for:
- Generic functions (def func[T](): ...)
- Generic classes (class X[T](): ...)
- Type aliases (type X = ...)
- New scoping when the new syntax is used within a class body
- Compiler and interpreter changes to support the new syntax and scoping rules

bpo-40939: Remove PEG parser easter egg (__new_parser__) ( #20802 )
...
It no longer serves a purpose (there's only one parser) and having "new" in any name will eventually look odd. Also, it impinges on a potential sub-namespace, `__new_...__`.

bpo-36143: Regenerate Lib/keyword.py from the Grammar and Tokens file using pgen (GH-12456)
...
Now that the parser generator is written in Python (Parser/pgen) we can make use of it to regenerate the Lib/keyword file that contains the language keywords instead of parsing the autogenerated grammar files. This also allows checking in the CI that the autogenerated files are up to date.

bpo-35975: Support parsing earlier minor versions of Python 3 (GH-12086)
...
This adds a `feature_version` flag to `ast.parse()` (documented) and `compile()` (hidden) that allow tweaking the parser to support older versions of the grammar. In particular if `feature_version` is 5 or 6, the hacks for the `async` and `await` keyword from PEP 492 are reinstated. (For 7 or higher, these are unconditionally treated as keywords, but they are still special tokens rather than `NAME` tokens that the parser driver recognizes.)

More trivial comment -> docstring transformations by Ka-Ping Yee,

who writes:
Here is batch 2, as a big collection of CVS context diffs.
Along with moving comments into docstrings, i've added a
couple of missing docstrings and attempted to make sure more
module docstrings begin with a one-line summary.
I did not add docstrings to the methods in profile.py for
fear of upsetting any careful optimizations there, though
i did move class documentation into class docstrings.
The convention i'm using is to leave credits/version/copyright
type of stuff in # comments, and move the rest of the descriptive
stuff about module usage into module docstrings. Hope this is
okay.

Here's a "keyword" module which, in the spirit of "token.py", updates
the list of keywords automatically from a source file (in this case,
"graminit.c" seemed like a reasonable choice, easier than "Grammar/Grammar").
You get "kwlist", a sorted list of keywords; "kwdict", a dictionary
mapping each keyword to 1; and "iskeyword", a function which tells
you if a given string happens to be a keyword.
