Upstart, the event/init daemon still being used by Ubuntu Linux rather than systemd or SysVinit, is now up to version 1.8. Compared to earlier releases
that brought more changes, Upstart 1.8 just brings two official changes over Upstart 1.7.
The first feature of Upstart 1.8 is the upstart-file-bridge, which allows for jobs to react to file events like file creation, modification, or deletion. Jobs can be spawned based upon these file events to certain files or glob matching.
The other change is upstart-monitor, which is a simple tool for either CLI or GUI usage that allows users and administrators to monitor event flows.
The brief release announcement for this rather straightforward Upstart 1.8 release can be viewed at Upstart-devel
