What's new in this version:

Security:
- http.server: Fix an open redirection vulnerability in the HTTP server when an URI path starts with //. Vulnerability discovered, and initial fix proposed, by Hamza Avvan.
- Fix memoryview use after free when accessing the backing buffer in certain cases

Core and Builtins:
- _PyPegen_Parser_New now properly detects token memory allocation errors
- Fix error detection in some builtin functions when keyword argument name is an instance of a str subclass with overloaded __eq__ and __hash__. Previously it could cause SystemError or other undesired behavior.
- ast.parse() will no longer parse parenthesized context managers when passed feature_version less than (3, 9). Patch by Shantanu Jain.
- ast.parse() will no longer parse assignment expressions when passed feature_version less than (3, 8). Patch by Shantanu Jain.
- Fix the column offsets for some expressions in multi-line f-strings ast nodes
- Fix an issue where a bytearray item assignment could crash if it’s resized by the new value’s __index__() method.
- Compile and run code with unpacking of extremely large sequences (1000s of elements). Such code failed to compile. It now compiles and runs correctly.
- Fixed a tokenizer crash when reading encoded files with syntax errors from stdin with non utf-8 encoded text
- Fix error for dictionary literals with invalid expression as value.
- Strengthened compiler overflow checks to prevent crashes when compiling very large source files.
- Fix some exponential backtrace case happening with deeply nested sequence patterns in match statements
- Fix the __text_signature__ for __get__() methods implemented in C. Patch by Jelle Zijlstra.
- Fixed a crash in _pickle.c from mutating collections during __reduce__ or persistent_id.
- Always round the allocated size for lists up to the nearest even number.
- Improve error message for some suites with syntax error before ‘:’

Library:
- Update bundled pip to 22.2.1
- Fix GC crash when deallocating _lsprof.Profiler by untracking it before calling any callbacks
- Fix IndexError in parsing invalid date in the email module
- Upgrade bundled setuptools to 63.2.0
- Upgrade bundled pip to 22.2
- Fix check for existence of os.EFD_CLOEXEC, os.EFD_NONBLOCK and os.EFD_SEMAPHORE flags on older kernel versions where these flags are not present
- Fix concurrent.futures.Executor.map() to cancel the currently waiting on future on an error - e.g. TimeoutError or KeyboardInterrupt.
- Fix fileinput module didn’t support errors option when inplace is true.
- Fix binding of unix socket to empty address on Linux to use an available address from the abstract namespace, instead of “0”.
- Fix crash when deallocating an instance of a subclass of _multiprocessing.SemLock
- SSLContext.set_default_verify_paths() now releases the GIL around SSL_CTX_set_default_verify_paths call. The function call performs I/O and CPU intensive work.
- Re-entrant calls to sys.setprofile() and sys.settrace() now raise RuntimeError.
- Fix bug where linecache.getline() fails on bad files with UnicodeDecodeError or SyntaxError. It now returns an empty string as per the documentation.
- Fix memory leak in pickle.Pickler when looking up dispatch_table
- Fixed types of struct module to be immutable
- Fix pickling and copying of typing.Tuple[()].
- Made _struct.Struct GC-tracked in order to fix a reference leak in the _struct module.
- Manual instantiation of ssl.SSLSession objects is no longer allowed as it lead to misconfigured instances that crashed the interpreter when attributes where accessed on them.
- inspect.iscoroutinefunction(), inspect.isgeneratorfunction(), and inspect.isasyncgenfunction() now properly return True for duck-typed function-like objects like instances of unittest.mock.AsyncMock.
- This makes inspect.iscoroutinefunction() consistent with the behavior of asyncio.iscoroutinefunction(). Patch by Mehdi ABAAKOUK.
- Fix double closing of file description in tempfile.
- Fixed names and __module__ value of weakref classes ReferenceType, ProxyType, CallableProxyType. It makes them pickleable.
- copy.copy() and copy.deepcopy() now always raise a TypeError if __reduce__() returns a tuple with length 6 instead of silently ignore the 6th item or produce incorrect result.
- Fix a multiprocessing bug where a global named resource (such as a semaphore) could leak when a child process is spawned (as opposed to forked).
- sqlite3 now correctly detects DML queries with leading comments. Patch by Erlend E. Aasland.
- Update sqlite3.Cursor.rowcount when a DML statement has run to completion. This fixes the row count for SQL queries like UPDATE ... RETURNING. Patch by Erlend E. Aasland.
- Suppress writing an XML declaration in open files in ElementTree.write() with encoding='unicode' and xml_declaration=None.
- Fix the importlib.resources.as_file() context manager to remove the temporary file if destroyed late during Python finalization: keep a local reference to the os.remove() function. Patch by Victor Stinner.
- Make multiprocessing.Pool raise an exception if maxtasksperchild is not None or a positive int.
- shutil.make_archive() no longer temporarily changes the current working directory during creation of standard .zip or tar archives.
- Move imports in SharedMemory methods to module level so that they can be executed late in python finalization.
- Fixed an issue with inconsistent trailing slashes in tarfile longname directories
- In QueueHandler, clear stack_info from LogRecord to prevent stack trace from being written twice
- Fix OSS audio support on NetBSD
- Fix ensurepip environment isolation for subprocess running pip
- Fix asyncio incorrect traceback when future’s exception is raised multiple times- sqlite3.Connection.iterdump() now handles databases that use AUTOINCREMENT in one or more tables

What's new in this version:

Improvements:
- Common graphic files: add GML extension
- Update EULA in Surfer for subscription licensing

Fixed:
- 3D View: default camera is far away when Map and layer have different coordinate systems
- 3D View: Export 3D: some surfaces export with the axis labels in the wrong location
- 3D View: Export to VRML: textured surfaces with blanked areas can lose surface color

What's new in this version:

- Correct a regression in the support added for encrypted PKCS#1 formatted private keys in the previous release that broke support for unencrypted PKCS#1 formatted private keys
- Increase the default buffer size for cluster messages from 43800 to 65536 bytes. This is expected to improve performance for large messages when running on Linux based systems.
- When using TLS with non-blocking writes and the NIO connector, ensure that flushing the buffers attempts to empty all of the output buffers
