Python 3.14 garbage collection rigamarole

This article discusses the changes to Python's garbage collector in version 3.14.0, which introduced incremental garbage collection to reduce pause times. However, due to reported memory pressure problems, the Python team reverted these changes in the 3.14.5 release. The article explains the technical details of the incremental GC and the reasons behind the reversion, targeting developers interested in Python internals and memory management.
