-- New development of new major version, update to 3.15.0~a1:
- - Tools/Demos
- - gh-139330: SBOM generation tool didn’t cross-check
- the version and checksum values against the
- Modules/expat/refresh.sh script, leading to the values
- becoming out-of-date during routine updates.
- - gh-132006: XCframeworks now include privacy manifests to
- satisfy Apple App Store submission requirements.
- - gh-138171: A script for building an iOS XCframework was
- added. As part of this change, the top level iOS folder has
- been moved to be a subdirectory of the Apple folder.
- - gh-137873: The iOS test runner has been simplified,
- resolving some issues that have been observed using
- the runner in GitHub Actions and Azure Pipelines test
- environments.
- - gh-137484: Have Tools/wasm/wasi put the build Python into a
- directory named after the build triple instead of “build”.
- - gh-137025: The wasm_build.py script has been removed.
- Tools/wasm/emscripten and Tools/wasm/wasi should be used
- instead, as described in the Dev Guide.
- - gh-137248: Add a --logdir option to Tools/wasm/wasi for
- specifying where to write log files.
- - gh-137243: Have Tools/wasm/wasi detect a WASI SDK install
- in /opt when it was directly extracted from a release
- tarball.
- - gh-136251: Fixes and usability improvements for
- Tools/wasm/emscripten/web_example
- - gh-135968: Stubs for strip are now provided as part of an
- iOS install.
- - gh-135379: The cases generator no longer accepts type
- annotations on stack items. Conversions to non-default
- types are now done explicitly in bytecodes.c and
- optimizer_bytecodes.c. This will simplify code generation
- for top-of-stack caching and other future features.
- - gh-134215: REPL import autocomplete only suggests private
- modules when explicitly specified.
- - Tests
- - gh-139208: Fix regrtest --fast-ci --verbose: don’t ignore
- the --verbose option anymore. Patch by Victor Stinner.
- - gh-138313: Restore skipped test and add janky workaround
- to prevent select buildbots from failing with a
- ResourceWarning.
- - 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.
- - gh-132815: Fix test__opcode: add JUMP_BACKWARD to
- specialization stats.
- - gh-135489: Show verbose output for failing tests during PGO
- profiling step with –enable-optimizations.
- - gh-135401: Add a new GitHub CI job to test the ssl module
- with AWS-LC as the backing cryptography and TLS library.
- - gh-135120: Add test.support.subTests().
- - gh-134567: Expose log formatter to users in
- TestCase.assertLogs. unittest.TestCase.assertLogs() will
- now optionally accept a formatter that will be used to
- format the strings in output if provided.
- - gh-133744: Fix multiprocessing interrupt test. Add an event
- to synchronize the parent process with the child process:
- wait until the child process starts sleeping. Patch by
- Victor Stinner.
- - gh-133682: Fixed test case
- test.test_annotationlib.TestStringFormat.test_displays
- which ensures proper handling of complex data structures
- (lists, sets, dictionaries, and tuples) in string
- annotations.
- - gh-133639: Fix
- TestPyReplAutoindent.test_auto_indent_default() doesn’t run
- input_code.
- - Security
- - gh-139700: Check consistency of the zip64 end of central
- directory record. Support records with “zip64 extensible
- data” if there are no bytes prepended to the ZIP file.
- - gh-139400: xml.parsers.expat: Make sure that parent
- Expat parsers are only garbage-collected once they
- are no longer referenced by subparsers created by

- 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. .
- - Multiple slashes and whitespaces between the last
- attribute and closing > are now ignored in both start and
- end tags. E.g. .
- - Multiple = between attribute name and value are no longer
- collapsed. E.g. produces attribute “foo”
- with value “=bar”.
- - gh-135661: Fix CDATA section parsing in
- html.parser.HTMLParser according to the HTML5 standard: ]
- ]> and ]] > no longer end the CDATA section. Add private

- how to parse <[CDATA[ — as a CDATA section in foreign
- content (SVG or MathML) or as a bogus comment in the HTML
- namespace.
- - gh-102555: Fix comment parsing in html.parser.HTMLParser
- according to the HTML5 standard. --!> now ends the comment.

- DeprecationWarnings if they were merely imported or
- accessed from their respective modules.
- - gh-135729: Fix unraisable exception during finalization
- when using concurrent.interpreters in the REPL.
- - gh-139076: Fix a bug in the pydoc module that was hiding

- - gh-138432: zoneinfo.reset_tzpath() will now convert any
- os.PathLike objects it receives into strings before adding
- them to TZPATH. It will raise TypeError if anything other

- os.PathLike object that represents a relative path, it will
- now raise ValueError instead of TypeError, and present a
- more informative error message.

- - gh-132876: ldexp() on Windows doesn’t round subnormal
- results before Windows 11, but should. Python’s
- math.ldexp() wrapper now does round them, so results may
- change slightly, in rare cases of very small results, on
- Windows versions before 11.
- - gh-133009: xml.etree.ElementTree: Fix a crash in
- Element.__deepcopy__ when the element is concurrently

- performing stateful operations in critical sections.
- - gh-127081: Fix libc thread safety issues with os by
- replacing getlogin with getlogin_r re-entrant version.
- - gh-127081: Fix libc thread safety issues with pwd by
- locking access to getpwall.
- - gh-132551: Make io.BytesIO safe in free-threaded build.
- - gh-107583: Fix Flag inversion when flag set has missing
- values (IntFlag still flips all bits); fix negative
- assigned values during flag creation (both Flag and IntFlag
- ignore missing values).
- - 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

- - gh-131788: Make ResourceTracker.send from multiprocessing
- re-entrant safe
- - gh-91349: Adjust default compressionlevel= to 6 (down from
- 9) in gzip and tarfile. It is the default level used by
- most compression tools and a better tradeoff between speed
- and performance.
- - gh-131146: Fix calendar.TextCalendar,
- calendar.HTMLCalendar, and the calendar CLI
- to display month names in the nominative case
- by adding calendar.standalone_month_name and
- calendar.standalone_month_abbr, which provide month names
- and abbreviations in the grammatical form used when a month
- name stands by itself, if the locale supports it.
- - gh-123471: Make concurrent iterations over itertools.cycle
- safe under free-threading.
- - 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.
- - gh-130999: Avoid exiting the new REPL and offer suggestions
- even if there are non-string candidates when errors occur.
- - gh-88473: Implement a fast path for datetime.date objects
- in datetime.date.today() which results in a 5x performance
- gain while proper subclasses retain their previous
- performance.
- - gh-126883: Add check that timezone fields are in
- range for datetime.datetime.fromisoformat() and
- datetime.time.fromisoformat(). Patch by Semyon Moroz.
- - gh-125028: functools.Placeholder cannot be passed to
- functools.partial() as a keyword argument.
- - gh-125843: If possible, indicate which curses C function or

- to invalid dists when retrieving by name.
- - gh-99631: The shelve module now accepts custom
- serialization and deserialization functions.
- - gh-119186: Slightly speed up os.walk() by calling
- os.path.join() less often.
- - gh-120170: Fix an issue in the _pickle extension module in
- which importing multiprocessing could change how pickle
- identifies which module an object belongs to, potentially
- breaking the unpickling of those objects.
- - gh-118981: Fix potential hang in
- multiprocessing.popen_spawn_posix that can happen when the
- child proc dies early by closing the child fds right away.
- - gh-105497: Fix flag mask inversion when unnamed flags
- exist.
- - gh-99813: ssl now uses SSL_sendfile internally when it is
- possible (see OP_ENABLE_KTLS). The function sends a file
- more efficiently because it performs TLS encryption in the
- kernel to avoid additional context switches. Patch by Illia
- Volochii.
- - gh-62824: Fix aliases for iso8859_8 encoding. Patch by Dave
- Goncalves.
- - gh-86155: html.parser.HTMLParser.close() no longer loses
- data when the
