Reverting the incremental GC in Python 3.14 and 3.15
Summary
The thread discusses reverting Python 3.14/3.15 incremental garbage collection back to the 3.13 generational GC due to memory pressure in production. It covers planned release schedules, PEP processes for reintroducing an incremental GC in 3.16, and the trade-offs between pause times, memory usage, and maintenance burden, with user feedback and benchmarking notes threaded through multiple posts. The discussion also considers optional experimentation and RC testing for patch releases.
