Proposed Release Schedule for SciPy 2.0.0

[tylerjereddy]

Hi all,

I’m proposing the release schedule for SciPy 2.0.0 below and I’m happy to hear feedback/requests for adjustments if needed. I included a few special links below for context about the major version bump. I’m initially proposing to mirror the cadence of the prior Dec-Jan release, but if we think 2.0.0 warrants a much slower rollout let me know. I don’t know if we gain much by proposing to delay intentionally–if something major comes up we can always do that.

• 2026-12-06T07:00:00Z branch maintenance/2.0.x
• 2026-12-09T07:00:00Z release 2.0.0rc1
• 2026-12-20T07:00:00Z release 2.0.0rc2 (if needed – probably)
• 2027-01-03T07:00:00Z final 2.0.0 release

Current tallies for 2.0.0 milestone:

• 63 open PRs
• 26 open issues

Special Information for 2.0.0 release:

• mailing list thread about making array types support public, and scoping comments: Making array types support public & SciPy 2.0
• preparation of the associated manuscript: https://github.com/scipy/scipy-articles
• sample downstream impact – sklearn plan to move array API support out of experimental

Thanks Tyler! This approach looks good to me. I agree it’s always possible to move the final release out later; for now I don’t think there’s a reason to expect trouble.

Sounds reasonable although we do still need to move ahead with turning on array api support
