- Tests
- gh-125041: Re-enable skipped tests for zlib on the
s390x architecture: only skip checks of the compressed
bytes, which can be different between zlib’s software
implementation and the hardware-accelerated implementation.
- gh-109396: Fix test_socket.test_hmac_sha1() in FIPS
mode. Use a longer key: FIPS mode requires at least of at
least 112 bits. The previous key was only 32 bits. Patch by
Victor Stinner.
- gh-100454: Fix SSL tests CI for OpenSSL 3.1+
- Security
- gh-126623: Upgrade libexpat to 2.6.4
- gh-122792: Changed IPv4-mapped ipaddress.IPv6Address to
consistently use the mapped IPv4 address value for deciding
properties. Properties which have their behavior fixed are
is_multicast, is_reserved, is_link_local, is_global, and
is_unspecified.
- Library
- gh-124651: Properly quote template strings in venv
activation scripts.
- gh-103848: Add checks to ensure that [ bracketed ] hosts
found by urllib.parse.urlsplit() are of IPv6 or IPvFuture
format.
- Documentation
- gh-95588: Clarified the conflicting advice given in the ast
documentation about ast.literal_eval() being “safe” for use
on untrusted input while at the same time warning that it
can crash the process. The latter statement is true and is
deemed unfixable without a large amount of work unsuitable

Notes for packagers of Python3

|
==============================
|
|
|
|
0. Faster build turnaround
|
|
--------------------------
|
|
|
|
By default, python builds with profile-guided optimization. This needs
|
|
an additional run of the test suite and it is generally slow.
|
|
PGO build takes around 50 minutes.
|
|
|
|
For development, use "--without profileopt" option to disable PGO. This
|
|
shortens the build time to ~5 minutes including test suite.
|
|
|
|
1. import_failed.map
|
|
----------------------
|
|
|
|
This is a mechanism installed as part of python3-base, that places shim modules
|
|
on python's path (through a generated zzzz-import-failed-hooks.pth file, so that
|
|
it is imported as much at the end as makes sense; and an _import_failed subdir
|
|
of /usr/lib/pythonX.Y). Then when the user tries to import a module that is part
|
|
of a subpackage, the ImportError will contain a helpful message telling them
|
|
which missing subpackage to install.
|
|
|
|
This can sometimes cause problems on non-standard configurations, if the pth
|
|
gets included too early (for instance if you are using a script to include all
|
|
pths by hand in some strange order). Just something to look out for.
