Big Changes that would justify a version 4 of Python
Consideration for a version 4 of Python centers around two major developments: an overhaul of the C API and the removal of the global interpreter lock (GIL). The C API is undergoing improvements to enhance usability and backward compatibility, prompting discussions on a potential transition plan that could lead to a future deprecation of the old API. This could align with the release of Python 4 as a way to streamline the language for better long-term support. Concurrently, there is active consideration of a proposal (PEP 703) aimed at eliminating the GIL, which would enable true multithreading capabilities within Python programs. This would necessitate substantial changes to the C struct headers and other foundational aspects of the language, further reinforcing the case for a major version change. Together, these factors indicate significant shifts in the underlying architecture of Python that could justify a version 4 release.
