flux-connectors v0.20.0

Release Notes

Action needed

• Stop every process using the old local credential store before upgrading. The new release
  prevents two current processes from writing one store, but older processes do not participate in
  that protection. Quiesce every 0.19.1 process before the first 0.20 open: an already-open legacy
  process can rewrite its cached v1 image and erase v2 recovery state. Once a transaction migrates
  the file, a newly started 0.19.1 process safely refuses its newer format.

New

• Hosts can recover credential changes coordinated with their own metadata after a crash. One
  complete credential update can be prepared invisibly, committed atomically or abandoned without
  resurrection. Explicit generation retirement keeps recovery history bounded, and the durable
  local store rejects a second writer for its lifetime.

Fixed

• Dependency examples and documentation links now point to the published packages. Copying an
  installation snippet or following API documentation no longer lands on an unrelated or missing
  package name.
