(forgot to remove it in #3219)

Add optional argument `compressed` to `zipapp.create_archive`, and add
option `--compress` to the command line interface of `zipapp`.

$^ is not portable.

Instead, simply pass 's' to ar.

bpo-11063, bpo-20519: avoid ctypes and improve import time for uuid.

Replace "restriction" with "restrictions".

bpo-31478: Fix an assertion failure in random.seed() in case a seed has a bad __abs__() method. (#3596)

Class execution requires that __prepare__() methods return
a proper execution namespace. Check for that immediately
after calling __prepare__(), rather than passing it through
to the code execution machinery and potentially triggering
SystemError (in debug builds) or a cryptic TypeError
(in release builds).

Patch by Oren Milman.

Fix the logic in python-config.sh to avoid attempting to substitute
prefix in a variable that might have already been subject to
substitution. This e.g. happened if @exec_prefix@ was defined as
"${prefix}" (which is the default of the configure script) -- in which
case the exec_prefix_build variable was initialized with
already-subtituted prefix, and then another round of substitution was
performed which might have resulted in duplicate prefix.

To avoid that, rename the variables so that the variables matching
likely configure names (prefix, exec_prefix) retain their original
values and a '_real' suffix is used for the real values of prefix.

Furthermore, replace the unnecessary prefix and exec_prefix
substitutions with direct prefix_real references since the sed
always replaced the whole string anyway by design.

- Remove the second mention about the `u` prefix
- Remove the second mention about numeric literals do not include a sign

Non-regression tests for the Expat 2.2.3 UTF-8 decoder bug.

bpo-31311: Fix a SystemError and a crash in ctypes._CData.__setstate__(), in case of a bad __dict__. (#3254)

Python requires C implementations provide memmove, so we shouldn't need to check for it. The only place using this configure check was expat, where we can simply always define HAVE_MEMMOVE.

The dunderless functions are preferred; dunder are retained for back compatilibity.

Mention that ``NewType`` can derive from another ``NewType``.

The original module-level class and method browser became a module
browser, with the addition of module-level functions, years ago.
Nested classes and functions were added yesterday.  For back-

Order dependence caused leak-test buildbots to fail when running test_idle repeatedly.
