date: mid-may (free-threading push)

wanted:

• pandas-3 everywhere
• streamlit and numba on free-threading
• Python-3.14 slim version 100% complete (as "deap" wheel arrived)
• Python-3.14.4 free-threading complete at 90%
• pylock.toml as the standard way to build with pip, requirement files still published this cycle
• Python-3.15.0 beta 1 ... with some free-threading wheels ?
• AI local
• AI help to further simplify WinPython

remark:

• numpy-2.5 will be more performant for free-threading than for multi-processing
• community effort is on the pep-803 free-threading stable abi3t for 3.15 beta1, that will unlock binary packages
• python-3.15 speed-up hopes (with pep-803):
  • JIT and internals: +10%
  • free-threading: square-root(number of physical threads on full cpus), so 5x end 2026
  • one time 10% bonus with tail call for 3.15 windows
  • ... so about 10%, up to 20% with JIT, up to 50% faster with free-threading
