- WASI support in CPython has been made easier for developers with tools like WASI dev containers and codespaces.
- PEP 816 was accepted, defining WASI compatibility handling starting with Python 3.15, locking down WASI and WASI SDK versions after the first beta.
- Future tasks include implementing a WASI build bundler, defining a platform tag for wheels, building dependencies like zlib, and enabling socket support requiring WASI 0.3 and threading.
