Releases

• 6.1.3:

  • 6.1.3 is out
  • Any issues reported so far?
    • pip install wheel from fresh 3.14 python environment because old setup tools is needed.

• 6.2.0:

  • Release manager - Sujaya
    • Paul S. will be backup if timelines slip etc
  • The release checklist can be found here
  • Are we releasing a new version of sasmodels and sasdata to support this?
    • YES
  • Semantic versioning as part of documentation for downstream users? -- bug, feature, or breaking?
    • sasview pacakge is but we should check what version number needs to be given to sasdata and sasmodels
  • Proposed release date: ~June 2026
    • This release has a lot in it. We therefore need to move soon on preparing for it.
    • We need to announce a code freeze date ASAP to the developer group. Needs to provide reasonable time for those without dedicated time to make arrangements.
      • May 15 code freeze feature
      • Sujaya to send information to developer list very soon on the freeze date as well as the fact that it will apply to all 3 packages.
    • Are there sections which can have a later code freeze (e.g. plugin portion of a model). If so what is it? Also needs announcing.
      • Maybe but let's not decide that now. If on the 15th there are models for which this is a question we can revisit.
      • Note that we had an issue when we did that for the 2 Yukawa though that one did not follow the normal plugin structure so even for models we should be careful.

ADRs?

• New draft of linting and formatting ADR: Code Linting and Formatting using Ruff
  • Will give folks a couple of weeks (next call) to comment before sending to developer list
• Anything else ready for discussion here?
