  • The scheduler now keeps track of how many jobs each worker is running.
  • The number of jobs is shown in the pool status.
  • The pool admin API has a drain operation, which pauses the worker and waits for the number of jobs to reach zero.
  • The admin CLI allows pause --wait to use this.
  • The scheduler reports progress back to the client.
  • The update command also now shows draining progress.

This is useful for scripts that need to wait for a worker to stop before continuing (e.g. when upgrading a build machine).
