* Added new :meth:`!reorganize` methods to :mod:`dbm.dumb` and :mod:`dbm.sqlite3`
which allow to recover unused free space previously occupied by deleted entries.
(Contributed by Andrea Oliveri in :gh:`134004`.)

* Add the ``'m'`` flag for :func:`dbm.gnu.open` which allows to disable
the use of :manpage:`mmap(2)`.
This may harm performance, but improve crash tolerance.
