PRs - This is a feature release, so the main focus is on new features and major changes:

sasview

• MultiSlicers by @jellybean2004 in
  #3970

• SizeDistribution by @jellybean2004 in NOT FOR 6.2.0!!

  • #3962 — Size Distribution calculator clean up (cleanup/type hints for new SD perspective shipping in 6.2.0)
  • #3963 — Single kernel call for volume and intensity (fixes #3418, SD bug fix; depends on #3962)
  • #3965 — Adds PDF report for Size Distribution (new feature for SD perspective in 6.2.0)
  • #3967 — Fix report preview background (fixes #3964, dark mode regression — recent issue) APPROVED

• auto upload binaries during CI if a tagged branch (needed for releases?) by @krzywon in

  • #3932 — Upload Binaries On Tag (CI release workflow — could be needed for release process itself)

• Is this for 6.2? - COULD BE - see notes in pull request

  • Docs Cleanup by @llimeht in
    • #3954 — Fix sphinx docs private members (cleans up the unreadable docs the user sees)

sasdata

• #202
  • merge after hackathon

sasmodels

• Add support for latest BUMPS version - IS IT NEEDED for 6.2? by @pkienzle in

  • #704
    • Merged to master. no need to cherry pick this as sasmodels 1.0.13 uses earlier bumps version. But should work either way

• NOT READY BUT DISCUSSED:

  • #704 torus elliptical shell model. Needs some work but we should encourage the author. This is a nice model!
  • #694 another truncated octahedron model untouched since January
    • PK to move it to explore and then merge so it can be kept for comparison but does not end up in the releases.

Acknowledgements

Will turn these ideas into an ADR for further discussion and eventual adoption - Paul Butler

• How should we acknowledge contributing institutions? Do we continue to use logos? If so how do we decide?
• The suggestion we currently have is:
  • We will remove the logos from the SasView application and rephrase the wording to avoid listing institutions.
  • We will add lists of affiliations to the people page on sasview.org, alongside a separate list of contributor camp hosts.
  • We will also update the grants section of the people page, and the contributors.tsv file in the SasView repo.
• We currently have around 30 contributing institutions, over 20 of which are universities.
• General consensus is that having full lists of institutions and/or logos on sasview.org is easier than in the application itself.
• Please let us know of any grants that we may be missing.

ADRs sent out for review

• New code should be formatted using a linter
• Automating Release Processes
