Nuitka 4.1 is a new stable release of the Python-to-C compiler. Key highlights include improved Python 3.14 compatibility (still experimental), extensive async code compatibility fixes, expanded generics support for Python 3.12+, and significant compilation scalability optimizations. The release consolidates fixes from hotfix versions 4.0.1 through 4.0.8, adds new UI options like --recommended-python-version, improves standalone package support for libraries like paddle, scipy, h5py, and flet_desktop, and introduces performance improvements to trace collection, plugin dispatch, and C code generation. Reproducible builds support was also added via a new Scons option.
