5. bpo-43162: [Enum] deprecate enum member.member access (GH-24486)

   In 3.5 (?) a speed optimization made it possible to access members as
   attributes of other members, i.e. ``Color.RED.BLUE``.  This was always
   discouraged in the docs, and other recent optimizations has made that
   one no longer necessary.  Because some may be relying on it anyway, it
   is being deprecated in 3.10, and will be removed in 3.11.

6. bpo-13501: allow choosing between readline and libedit (GH-24189)

   In contrast to macOS, libedit is available as its own include file and
   library on Linux systems to prevent file name clashes. So if both
   libraries are available on the system, readline is currently chosen by
   default; and if only libedit is available, it is not found at all. This
   patch adds a way to link against libedit by adding the following
   arguments to configure:
   
     --with-readline           link against libreadline (the default)
     --with-readline=editline  link against libeditline
     --with-readline=no        disable building the readline module
     --without-readline        (same)
   
   The runtime detection of libedit vs. readline was already done in commit
   7105319 (2019-12-04, serge-sans-paille: "bpo-38634: Allow
   non-apple build to cope with libedit (GH-16986)").
   
   Fixes: GH-12076 ("bpo-13501 Build or disable readline with Editline")
   Fixes: bpo-13501 ("Make libedit support more generic; port readline / libedit to FreeBSD")

1. bpo-40692: Run more test_concurrent_futures tests (GH-20239)

   In the case of multiprocessing.synchronize() being missing, the
   test_concurrent_futures test suite now skips only the tests that
   require multiprocessing.synchronize().
   
   Validate that multiprocessing.synchronize exists as part of
   _check_system_limits(), allowing ProcessPoolExecutor to raise
   NotImplementedError during __init__, rather than crashing with
   ImportError during __init__ when creating a lock imported from
   multiprocessing.synchronize.
   
   Use _check_system_limits() to disable tests of
   ProcessPoolExecutor on systems without multiprocessing.synchronize.
   
   Running the test suite without multiprocessing.synchronize reveals
   that Lib/compileall.py crashes when it uses a ProcessPoolExecutor.
   Therefore, change Lib/compileall.py to call _check_system_limits()
   before creating the ProcessPoolExecutor.
   
   Note that both Lib/compileall.py and Lib/test/test_compileall.py
   were attempting to sanity-check ProcessPoolExecutor by expecting
   ImportError. In multiprocessing.resource_tracker, sem_unlink() is also absent
   on platforms where POSIX semaphores aren't available. Avoid using
   sem_unlink() if it, too, does not exist.

5. Fix dependabot.yml file (GH-24443)

   The `target-branch` field doesn't seem to support array.
   Since it defaults to the default branch anyway, we should just remove the `target-branch` field from the config.
