• melange
  • melange is tied to 4.14 for now but plans to stay in sync with the compiler
  • it can be moved to its own CI job so that we can test the rest with 5.1
  • to run the melange test suite, Rudi suggests attaching to a special alias rather than using enabled_if
  • can be released in 3.8, but under 0.1 or 1.0?
    • those have different requirements since we're supporting 1.x even after 2.0 is out
• adapting the meeting schedule to Australia, Europe, US west coast
  • we'll run next meeting at a time that works for Europe and Australia. Tentative schedule is to switch between the two at each meeting. Can schedule more meetings if necessary.
• 3.8 status
  • alpha1 submitted as is to opam-repo-ci: no regressions (but only shallow ones can be found like this - trickier regressions happen as people update to (lang dune 3.8))
  • milestone check:
    • nix signing has two similar implementations: https://github.com/ocaml/dune/pull/6975 and https://github.com/ocaml/dune/pull/7183
    • #7026 - Rudi will add a warning if he has time but this could be postponed
    • #7047 - waiting for review
    • #4244 - waiting for review
    • #7376 (cinaps symlinks). maybe cinaps itself uses realpath or something that breaks with symlinks. Ali will try with hardlinks.
    • #6865 (menhir explain). Rudi suggest adding the explain file as a target.
    • #7419 (dune install -p). This has been broken for a long time and is not a regression. Moving off Common.term is a good idea. There's a risk of removing a used option (due to globals) but we can take it. Rather than merge the partial fix we can leave it off the milestone and ship a proper fix.
    • #7373 - basically done. Melange will need this
    • #7364 (odoc support dir). using .odoc_support sounds good, as it should prevent conflicts with user content and be included in github pages. Rudi notes that we could create a _build/doc/<context> directory like we do for install, and remove leading underscores from some directories.
  • docs situation: we're halfway through the migration so the table of contents is not super pretty but this can be fixed by adding some temporary headers for the release. https://github.com/ocaml/dune/issues/7584 created for this.
