Future Python will remove GIL
published on 2023/08/01
Here is the plan:
Short term, an unsupported experimental version of Python without the GIL is published in parallel to the regular one. Target is 3.13/3.14.
Mid-term, the no-GIL version is marked as officially supported, but is still just an alternative to Python with GIL. A target date is announced to make it the default once. This will happen only after the community has shown enough support for it, and will take several years.
Long-term, no-GIL becomes the default. Before this, the core devs can reverse the decision and abort the no-GIL project if it proves to have a bad ROI.
