Hi All, I would like to inform you about recent porting of projects to Cython 3. Recently, I participated in migration of 3 bigger projects to Cython 3:
* Scipy - scipy main branch is currently compilable with Cython 3 with test suite passing. Cython 3 master branch is used in CI to ensure that all changes are compatible with Cython 3. * Pandas - pandas library is compilable with Cython 3, the test suite is passing except one test case (not caused by Cython in my opinion) - https://github.com/pandas-dev/pandas/issues/53125 * scikit-image - library is compilable with Cython 3 (test suite was not run though) When migrating to Cython 3, I was able to find out several issues in the Cython, all of them are merged in master now. Hence, I would like to ask about next steps. It would help greatly to release Cython 3 beta3. This will allow me to pin scipy CI to real pre-release instead of master branch. Moreover, I would like to ask whether we can do the final Cython 3 release after beta 3. The rationale is that the projects won't start really using Cython 3 until we do the final release. Now, we have 3 big users of Cython migrated, hence I think we have some confidence that Cython 3 is ready. What do you think? Thanks, Matus
