• Pool will start/complete when adding runs in a particular state.
• PriorityPool will listen to when the priority changes and re-order its queue

• [BC] New Pool: PriorityPool that supports:
  • priority for each run
  • maximum number of processes to run at a time
• Pool has become simpler, and just runs all child runs at the same time
  • [BC] max simultaneous option has been moved to PriorityPool
• new event: SUCCESSFUL only gets triggered when the run succeeds.
  • [BC] event: COMPLETE will get triggered for failed runs now too.
• Adds PoolLogger to write everything that happens to each pool and run.

• Adds a CallbackRun to run some php code. Note this will not be asynchronous.

[BC]

• Re-works the backend to change how Lines and Tables work with pools
• Re-works the events system to allow multiple listeners
• Supports progress and duration on runs

Allows pools to be run instantly (as soon as any process is added, and always run from then on)

• Adds Lines class to show the output of all the processes as they happen in-line.
• Modifies the callback definition (backwards compatible) to allow the type of each output from the process.
• Every output from the process is sent via callback now.
• Added flags to determine if onProgress should be on call process output or process poll or both.

Specify a maximum number of processes to run concurrently.

• Adds Table::setShowOutput flag to display the last line from each process
• Updates graze/console-diff-renderer to format before generating the diff

Change the Table class to use OutputInterface instead of ConsoleOutputInterface
