Hi all,

I’m proposing the release schedule for SciPy 1.16.0 below and I’m happy to hear feedback/requests for adjustments if needed.

Date Event
May 17, 2025 Branch maintenance/1.16.x
May 21, 2025 SciPy 1.16.0rc1 release
June 4, 2025 SciPy 1.16.0rc2 release (if needed)
June 18, 2025 SciPy 1.16.0 final release
  • Current count of open issues with 1.16.0 milestone on GitHub: 19
  • Current count of open PRs with 1.16.0 milestone on GitHub: 40

The schedule is somewhat adjusted to avoid work-related and PTO travel periods and to (hopefully) leverage high-bandwidth in person interactions at the summit May 10-15–ideally this will help substantially reduce the count of leftover blockers to branching.

Will probably aim for final release a little bit after NumPy 2.3.0 to ensure full support for that. Based on Chuck’s most recent plans, we’re branching a few days after him I think.

It would be good to have Windows ARM wheels, but that’s going to depend on OpenBLAS and numpy as well.
