- Update to 3.14.0~b4:
- Tools/Demos
- gh-135968: Stubs for strip are now provided as part of an
iOS install.
- gh-133600: Backport file reorganization for .
Tools/wasm/wasi This should make backporting future code .
changes easier. It also simplifies instructions around how.
to do WASI builds in the devguide .
- Tests
- gh-135966: The iOS testbed now handles the app_packages
folder as a site directory.
- gh-135494: Fix regrtest to support excluding tests from
--pgo tests. Patch by Victor Stinner.
- Security
- gh-136053: marshal: fix a possible crash when deserializing
slice objects.
- gh-135661: Fix parsing start and end tags in
html.parser.HTMLParser according to the HTML5 standard.
- Whitespaces no longer accepted between </ and the tag
name. E.g. </ script> does not end the script section.
- Vertical tabulation (\v) and non-ASCII whitespaces no
longer recognized as whitespaces. The only whitespaces
are \t\n\r\f and space.
- Null character (U+0000) no longer ends the tag name.
- Attributes and slashes after the tag name in end tags are
now ignored, instead of terminating after the first > in
quoted attribute value. E.g. </script/foo=">"/>.
- Multiple slashes and whitespaces between the last
attribute and closing > are now ignored in both start and
end tags. E.g. <a foo=bar/ //>.
- Multiple = between attribute name and value are no longer
collapsed. E.g. <a foo==bar> produces attribute “foo”
with value “=bar”.
- Whitespaces between the = separator and attribute name or
value are no longer ignored. E.g. <a foo =bar> produces
two attributes “foo” and “=bar”, both with value None; <a
foo= bar> produces two attributes: “foo” with value “”
and “bar” with value None.
- gh-102555: Fix comment parsing in html.parser.HTMLParser
according to the HTML5 standard. --!> now ends the comment.
-- > no longer ends the comment. Support abnormally ended
empty comments <--> and <--->.
- Library
- gh-136286: Fix pickling failures for protocols 0 and 1 for
many objects realted to subinterpreters.
- gh-136316: Improve support for evaluating nested forward
references in typing.evaluate_forward_ref().
- gh-85702: If zoneinfo._common.load_tzdata is given a
package without a resource a zoneinfo.ZoneInfoNotFoundError
is raised rather than a PermissionError. Patch by Victor
Stinner.
- gh-136028: Fix parsing month names containing “İ”
(U+0130, LATIN CAPITAL LETTER I WITH DOT ABOVE) in
time.strptime(). This affects locales az_AZ, ber_DZ, ber_MA
and crh_UA.
- gh-135995: In the palmos encoding, make byte 0x9b decode to
› (U+203A - SINGLE RIGHT-POINTING ANGLE QUOTATION MARK).
- gh-53203: Fix time.strptime() for %c and %x formats on
locales byn_ER, wal_ET and lzh_TW, and for %X format on
locales ar_SA, bg_BG and lzh_TW.
- gh-91555: An earlier change, which was introduced in
3.14.0b2, has been reverted. It disabled logging for
a logger during handling of log messages for that
logger. Since the reversion, the behaviour should be as it
was before 3.14.0b2.
- gh-135878: Fixes a crash of types.SimpleNamespace on free
threading builds, when several threads were calling its
__repr__() method at the same time.
- gh-135836: Fix IndexError in
asyncio.loop.create_connection() that could occur when
non-OSError exception is raised during connection and
socket’s close() raises OSError.
- gh-135836: Fix IndexError in
asyncio.loop.create_connection() that could occur when the
Happy Eyeballs algorithm resulted in an empty exceptions
list during connection attempts.
- gh-135855: Raise TypeError instead of SystemError when
_interpreters.set___main___attrs() is passed a non-dict
object. Patch by Brian Schubert.
- gh-135815: netrc: skip security checks if os.getuid() is
missing. Patch by Bénédikt Tran.
- gh-135640: Address bug where it was possible to call
xml.etree.ElementTree.ElementTree.write() on an ElementTree
object with an invalid root element. This behavior blanked
the file passed to write if it already existed.
- gh-135645: Added supports_isolated_interpreters field to
sys.implementation.
- gh-135646: Raise consistent NameError exceptions in
annotationlib.ForwardRef.evaluate()
- gh-135557: Fix races on heapq updates and list reads on the
free threaded build.
- gh-119180: Only fetch globals and locals if necessary in
annotationlib.get_annotations()
- gh-135561: Fix a crash on DEBUG builds when an HACL* HMAC
routine fails. Patch by Bénédikt Tran.
- gh-135487: Fix reprlib.Repr.repr_int() when given integers
with more than sys.get_int_max_str_digits() digits. Patch
by Bénédikt Tran.
- gh-135335: multiprocessing: Flush stdout and stderr after
preloading modules in the forkserver.
- gh-135069: Fix the “Invalid error handling” exception in
encodings.idna.IncrementalDecoder to correctly replace the
‘errors’ parameter.
- gh-130662: +Accept leading zeros in precision and width
fields for +:class:Decimal formatting, for example
format(Decimal(1.25), '.016f').
- gh-130662: Accept leading zeros in precision and
width fields for Fraction formatting, for example
format(Fraction(1, 3), '.016f').
- gh-87790: Support underscore and comma as thousands
separators in the fractional part for Fraction’s
formatting. Patch by Sergey B Kirpichev.
- gh-87790: Support underscore and comma as thousands
separators in the fractional part for Decimal’s
formatting. Patch by Sergey B Kirpichev.
- gh-130664: Handle corner-case for Fraction’s formatting:
treat zero-padding (preceding the width field by a zero
('0') character) as an equivalent to a fill character of
'0' with an alignment type of '=', just as in case of
float’s.
- Documentation
- gh-136155: EPUB builds are fixed by excluding
non-XHTML-compatible tags.
- Core and Builtins
- gh-109700: Fix memory error handling in
PyDict_SetDefault().
- gh-78465: Fix error message for cls.__new__(cls, ...) where
cls is not instantiable builtin or extension type (with
tp_new set to NULL).
- gh-129958: Differentiate between t-strings and f-strings
in syntax error for newlines in format specifiers of
single-quoted interpolated strings.
- gh-135871: Non-blocking mutex lock attempts now return
immediately when the lock is busy instead of briefly
spinning in the free threading build.
- gh-135106: Restrict the trashcan mechanism to GC’ed objects
and untrack them while in the trashcan to prevent the GC
and trashcan mechanisms conflicting.
- gh-135607: Fix potential weakref races in an object’s
destructor on the free threaded build.
- gh-135608: Fix a crash in the JIT involving attributes of
modules.

when sys.remote_exec() is called and migrate
remote_debugger_script to cpython.remote_debugger_script.
- gh-134280: Disable constant folding for ~ with a boolean
argument. This moves the deprecation warning from compile
time to runtime.
- C API
- gh-135906: Fix compilation errors when compiling the
internal headers with a C++ compiler.
- Build

Python 3 in SUSE
==============
* Subpackages *
Python 3 is split into several subpackages, based on external dependencies.
The main package 'python3' has soft dependencies on all subpackages needed to
assemble the standard library; however, these might not all be installed by default.
If you attempt to import a module that is currently not installed, an ImportError is thrown,
with instructions to install the missing subpackage. Installing the subpackage might result
in installing libraries that the subpackage requires to function.
* ensurepip *
The 'ensurepip' module from Python 3 standard library (PEP 453) is supposed to deploy
a bundled copy of the pip installer. This makes no sense in a managed distribution like SUSE.
Instead, you need to install package 'python3-pip'. Usually this will be installed automatically
with 'python3'.
Using 'ensurepip' when pip is not installed will result in an ImportError with instructions
to install 'python3-pip'.
* Documentation *
You can find documentation in seprarate packages: python3-doc and
python3-doc-pdf. These contan following documents:
Tutorial, What's New in Python, Global Module Index, Library Reference,
Macintosh Module Reference, Installing Python Modules, Distributing Python
Modules, Language Reference, Extending and Embedding, Python/C API,
Documenting Python
The python3-doc package constains many text files from source tarball.
* Interactive mode *
Interactive mode is by default enhanced with of history and command completion.
If you don't like these features, you can unset the PYTHONSTARTUP variable
in your .profile or disable it system wide in /etc/profile.d/python.sh.
