Python 3.12 का पुराना संस्करणहरू डाउनलोड गर्नुहोस्

macOS
- gh-124111: Update macOS installer to use Tcl/Tk 8.6.16.
- gh-131423: Update macOS installer to use OpenSSL 3.0.16. Patch by Bénédikt Tran.
- gh-131025: Update macOS installer to ship with SQLite 3.49.1.
- gh-91132: Update macOS installer to use ncurses 6.5.
Windows
- gh-131423: Update bundled version of OpenSSL to 3.0.16. The new build also disables uplink support, which may be relevant to embedders but has no impact on normal use.
- gh-131025: Update Windows installer to ship with SQLite 3.49.1.
- gh-131020: pylauncher correctly detects a BOM when searching for the shebang. Fix by Chris Eibl.
Tools/Demos
- gh-131852: msgfmt no longer adds the POT-Creation-Date to generated .mo files for consistency with GNU msgfmt.
- gh-85012: Correctly reset msgctxt when compiling messages in msgfmt.
Tests
- gh-131050: test_ssl.test_dh_params is skipped if the underlying TLS library does not support finite-field ephemeral Diffie-Hellman.
- gh-119727: Add --single-process command line option to Python test runner (regrtest). Patch by Victor Stinner.
Security
- gh-131809: Update bundled libexpat to 2.7.1
- gh-131261: Upgrade to libexpat 2.7.0
- gh-127371: Avoid unbounded buffering for tempfile.SpooledTemporaryFile.writelines(). Previously, disk spillover was only checked after the lines iterator had been exhausted. This is now done after each line is written.
- gh-121284: Fix bug in the folding of rfc2047 encoded-words when flattening an email message using a modern email policy. Previously when an encoded-word was too long for a line, it would be decoded, split across lines, and re-encoded. But commas and other special characters in the original text could be left unencoded and unquoted. This could theoretically be used to spoof header lines using a carefully constructed encoded-word if the resulting rendered email was transmitted or re-parsed.
Library
- gh-116608: undeprecate functional API for importlib.resources
- gh-132075: Fix possible use of socket address structures with uninitialized members. Now all structure members are initialized with zeroes by default.
- gh-132002: Fix crash when deallocating contextvars.ContextVar with weird unahashable string names.
- gh-131668: socket: Fix code parsing AF_BLUETOOTH socket addresses.
- gh-131492: Fix a resource leak when constructing a gzip.GzipFile with a filename fails, for example when passing an invalid compresslevel.
- gh-131325: Fix sendfile fallback implementation to drain data after writing to transport in asyncio.
- gh-129843: Fix incorrect argument passing in warnings.warn_explicit().
- gh-131204: Use monospace font from System Font Stack for cross-platform support in difflib.HtmlDiff.
- gh-131045: Fix issue with __contains__, values, and pseudo-members for enum.Flag.
- gh-130959: Fix pure-Python implementation of datetime.time.fromisoformat() to reject times with spaces in fractional part (for example, 12:34:56.400 +02:00), matching the C implementation. Patch by Michał Gorny.
- gh-130637: Add validation for numeric response data in poplib.POP3.stat() method
- gh-130461: Remove .. index:: directives from the uuid module documentation. These directives previously created entries in the general index for getnode() as well as the uuid1(), uuid3(), uuid4(), and uuid5() constructor functions.
- gh-130285: Fix corner case for random.sample() allowing the counts parameter to specify an empty population. So now, sample([], 0, counts=[]) and sample('abc', k=0, counts=[0, 0, 0]) both give the same result as sample([], 0).
- gh-130250: Fix regression in traceback.print_last().
- gh-118761: Reverts a change in the previous release attempting to make some stdlib imports used within the subprocess module lazy as this was causing errors during __del__ finalizers calling methods such as terminate, or kill, or send_signal.
- gh-130164: Fixed failure to raise TypeError in inspect.Signature.bind() for positional-only arguments provided by keyword when a variadic keyword argument (e.g. **kwargs)

Tests
- gh-127906: Test the limited C API in test_cppext. Patch by Victor Stinner.
- gh-127906: Backport test_cext from the main branch. Patch by Victor Stinner.
- gh-127637: Add tests for the dis command-line interface. Patch by Bénédikt Tran.
Security
- gh-105704: When using urllib.parse.urlsplit() and urllib.parse.urlparse() host parsing would not reject domain names containing square brackets ([ and ]). Square brackets are only valid for IPv6 and IPvFuture hosts according to RFC 3986 Section 3.2.2.
- gh-127655: Fixed the asyncio.selector_events._SelectorSocketTransport transport not pausing writes for the protocol when the buffer reaches the high water mark when using asyncio.WriteTransport.writelines().
- gh-126108: Fix a possible NULL pointer dereference in PySys_AddWarnOptionUnicode().
- gh-80222: Fix bug in the folding of quoted strings when flattening an email message using a modern email policy. Previously when a quoted string was folded so that it spanned more than one line, the surrounding quotes and internal escapes would be omitted. This could theoretically be used to spoof header lines using a carefully constructed quoted string if the resulting rendered email was transmitted or re-parsed.
- gh-119511: Fix a potential denial of service in the imaplib module. When connecting to a malicious server, it could cause an arbitrary amount of memory to be allocated. On many systems this is harmless as unused virtual memory is only a mapping, but if this hit a virtual address size limit it could lead to a MemoryError or other process crash. On unusual systems or builds where all allocated memory is touched and backed by actual ram or storage it could’ve consumed resources doing so until similarly crashing.
Library
- gh-129502: Unlikely errors in preparing arguments for ctypes callback are now handled in the same way as errors raised in the callback of in converting the result of the callback – using sys.unraisablehook() instead of sys.excepthook() and not setting sys.last_exc and other variables.

- gh-128550: Removed an incorrect optimization relating to eager tasks in asyncio.TaskGroup that resulted in cancellations being missed.
- gh-128991: Release the enter frame reference within bdb callback
- gh-128961: Fix a crash when setting state on an exhausted array.array iterator.
- gh-128916: Do not attempt to set SO_REUSEPORT on sockets of address families other than AF_INET and AF_INET6, as it is meaningless with these address families, and the call with fail with Linux kernel 6.12.9 and newer.
- gh-128679: Fix tracemalloc.stop() race condition. Fix tracemalloc to support calling tracemalloc.stop() in one thread, while another thread is tracing memory allocations. Patch by Victor Stinner.
- gh-128562: Fix possible conflicts in generated tkinter widget names if the widget class name ends with a digit.
- gh-128552: Fix cyclic garbage introduced by asyncio.loop.create_task() and asyncio.TaskGroup.create_task() holding a reference to the created task if it is eager.
- gh-128479: Fix asyncio.staggered.staggered_race() leaking tasks and issuing an unhandled exception.
- gh-88834: Unify the instance check for typing.Union and types.UnionType: Union now uses the instance checks against its parameters instead of the subclass checks.
- gh-128302: Fix xml.dom.xmlbuilder.DOMEntityResolver.resolveEntity(), which was broken by the Python 3.0 transition.
- gh-128302: Allow xml.dom.xmlbuilder.DOMParser.parse() to correctly handle xml.dom.xmlbuilder.DOMInputSource instances that only have a systemId attribute set.
- gh-112064: Fix incorrect handling of negative read

- gh-113785: csv now correctly parses numeric fields (when used with csv.QUOTE_NONNUMERIC) which start with an escape character.
- gh-112182: asyncio.futures.Future.set_exception() now transforms StopIteration into RuntimeError instead of hanging or other misbehavior. Patch contributed by Jamie Phan.
- gh-108172: webbrowser honors OS preferred browser on Linux when its desktop entry name contains the text of a known browser name.
- gh-102988: email.utils.getaddresses() and email.utils.parseaddr() now return ('', '') 2-tuples in more situations where invalid email addresses are encountered instead of potentially inaccurate values. Add optional strict parameter to these two functions: use strict=False to get the old behavior, accept malformed inputs. getattr(email.utils, 'supports_strict_parsing', False) can be use to check if the strict paramater is available. Patch by Thomas Dwyer and Victor Stinner to improve the CVE-2023-27043 fix.
- gh-99437: runpy.run_path() now decodes path-like objects, making sure __file__ and sys.argv[0] of the module being run are always strings.

- gh-122527: Fix a crash that occurred when a PyStructSequence was deallocated after its type’s dictionary was cleared by the GC. The type’s tp_basicsize now 

Windows
- gh-122573: The Windows build of CPython now requires 3.10 or newer.
Tests
- gh-59022: Add tests for pkgutil.extend_path(). Patch by Andreas Stocker.
- gh-99242: os.getloadavg() may throw OSError when running regression tests under certain conditions (e.g. chroot). This error is now caught and ignored, since reporting load average is optional.
- gh-121084: Fix test_typing random leaks. Clear typing ABC caches when running tests for refleaks (-R option): call _abc_caches_clear() on typing abstract classes and their subclasses. Patch by Victor Stinner.
- gh-121160: Add a test for readline.set_history_length(). Note that this test may fail on readline libraries.
- gh-121200: Fix test_expanduser_pwd2() of test_posixpath. Call getpwnam() to get pw_dir, since it can be different than getpwall() pw_dir. Patch by Victor Stinner.
