🚮 Python 3.14's garbage collector was such a "hit" that the team had to yank it out faster than you can say "incremental memory mismanagement." 🤦‍♂️ Apparently, the only thing it collected was complaints. 🙄

Python 3.14 garbage collection rigamarole - The Consensus

Python 3.14.0 introduced a new incremental garbage collector. But reports of higher memory usage caused the Python team to revert the garbage collector changes in 3.14.5.<br /><br />We investigate how memory management works in Python and workloads that perform best and worst for the incremental garbage collector.

Reverting the incremental GC in Python 3.14 and 3.15

Python 3.14 shipped with a new incremental garbage collector. However, we’ve had a number of reports of significant memory pressure in production environments. We’ve decided to revert it in both 3.14 and 3.15, and go back to the generational GC from 3.13. 3.15 is still in alpha, so such changes are fine. For 3.14, it is unusual for a patch release, but the old GC is a known quantity, the new incremental GC didn’t go through the PEP process, and was rolled back just before the final release of ...

Python 3.14.5 final is the fifth maintenance release of 3.14, containing around 154 bugfixes, build improvements and documentation changes since 3.14.4. Garbage collector Notably, the garbage collector (GC) has changed in Python 3.14.5. 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 of significant memory pressure in production environments.

Python 3.14.5 release candidate

Hey @hugovk, we are working on pushing this rc to Fedora Rawhide (development version), which is not yet updated to 3.15. That should give us some feedback, hopefully, but it will take a while before we get some. If the final is to be released in 2 days, I am afraid we will arrive with feedback (if any) too late.
