New Items

• Issue 11532 somehow related to Issue 11459

  • Summary: Something that was in v4.x (CLI and MCA params) is now broken.
  • We probably either need a code fix or a doc fix.
  • We need an answer by v5.0.0 as this is a break in ShellScripts compatibility.

• OAC submodule needs update by rc11

• FAQ changes - Anything else that needs progress.

  • Not a blocker for v5.0.0

• MPIR Shim (https://github.com/openpmix/mpir-to-pmix-guide) went away.
