gc
--
* Python 3.14.0-3.14.4 shipped with a new incremental garbage collector.
However, due to a number of `reports
<https://github.com/python/cpython/issues/142516>`__
of significant memory pressure in production environments,
it has been reverted back to the generational GC from 3.13.
This is the GC now used in Python 3.14.5 and later and Python 3.15.
