- Update to 3.11.0b4:
- Fixes many bugs and adds following more significant changes
- Security
  - gh-68966: The deprecated mailcap module now refuses to inject
    Coreunsafe text (filenames, MIME types, parameters) into
    shell Corecommands. Instead of using such text, it will
    warn and act Coreas if a match was not found (or for test
    commands, as if the Coretest failed). and Builtins
  - gh-93516: Lazily create a table mapping bytecode offsets to
    line numbers to speed up calculation of line numbers when
    tracing.
  - gh-93461: importlib.invalidate_caches() now drops entries
    from sys.path_importer_cache with a relative path as
    name. This solves a caching issue when a process changes its
    current working directory.
  - FileFinder no longer inserts a dot in the path, e.g.
    /egg/./spam is now /egg/spam.
Library
  - gh-93896: Fix asyncio.run() and
    unittest.IsolatedAsyncioTestCase to always the set event loop
    as it was done in Python 3.10 and earlier. Patch by Kumar
    Aditya.
  - gh-94101: 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.
  - gh-83658: Make multiprocessing.Pool raise an exception if
    maxtasksperchild is not None or a positive int.
  - gh-61162: Clarify sqlite3 behavior when Using the connection
    as a context manager.
Tools/Demos
  - gh-94538: Fix Argument Clinic output to custom file
    destinations. Patch by Erlend E. Aasland.
C API
  - gh-93937: The following frame functions and type are now
    directly available with #include <Python.h>, it’s no longer
    needed to add #include <frameobject.h>:
        PyFrame_Check()
        PyFrame_GetBack()
        PyFrame_GetBuiltins()
        PyFrame_GetGenerator()
        PyFrame_GetGlobals()
        PyFrame_GetLasti()
        PyFrame_GetLocals()
        PyFrame_Type
