Notable changes in 3.14.5
=========================

gc
--

* The incremental garbage collector shipped in Python 3.14.0-3.14.4 has been
reverted back to the generational garbage collector from 3.13,
due to a number of `reports
<https://github.com/python/cpython/issues/142516>`__
of significant memory pressure in production environments.
See :ref:`whatsnew314-incremental-gc` for details.
