2.0.0 (December 4, 2016)

Major changes

• Added support for aborting jobs. Call TrackedJob#abort method to abort a running job, which will abort the job if possible and reject the job with a JobAbortedError. A job's worker process is notified so that it can gracefully abort and cleanup. (#4)
• Added support for controlling concurrently running jobs. Adds a base JobExecutor class for custom logic, but also includes a built-in implementation (JobExecutorBuiltin) that optionally limits the maximum number of concurrently running jobs. (#5)

Breaking changes

• Changed JobWorkerMediator#started to only set to true once the startup confirmation is received. (from #4)
• Changed HubManager#queueJob to add created TrackedJob instances to HubManager#jobExecutor and no longer call TrackedJob#run. As a result, TrackedJob will be in a pre-run state directly after HubManager#queueJob. (from #5)

Breaking changes only if extending jobhub classes

• Added abstract JobWorkerMediator#sendAbortMessage method. (from #4)
• Renamed JobWorkerIPC#attachIPCChecks to attachToIPC.
• Renamed JobWorkerIPC#detatchIPCChecks to detatchFromIPC.

Notable non-breaking changes

• Added JobWorkerMediator#forked which is set to true on child process fork, replacing the previous behavior of JobWorkerMediator#started. (from #4)
• Added TrackedJob#isSettled to determine if a job succeeded or failed.
• Added 6th argument to workerBuildJobArg middleware to add abort listener. (from #4)
• Added HubManager#jobExecutor member property which is an instance of a JobExecutor abstract class. TrackedJob instances are added to JobExecutor which is then responsible for calling TrackedJob#run. (from #5)
• Added jobExecutorClass and jobExecutorOptions options to HubManager options to specify the constructor to use for HubManager#jobExecutor and the options to pass to the instance.
• Changed TrackedJob#then/catch to work before TrackedJob#run is called. Previously they would return a rejected Promise before the job was run.

Documentation changes

• Added jsdoc for workerLoadJob and workerBuildJobArg middleware.
