Some how in the flurry of the last few days I managed to miss that osTicket 1.7RC-5 was released on the 19th. Peter (dev) also states that they expect to ship 1.7 ST within 2 weeks.
OSTicket is a popular [free] open source help desk software or trouble ticketing system built on MySQL/PHP. It allows users or clients to open a ticket and describe the problem that they are experiencing so that your staff can track and update their trouble ticket easily and send out notifications with each update. It can also be used to monitor email accounts and automatically open new tickets when email arrives.
You can get the latest RC version over at Github. As a reminder this version is for developers and enthusiasts only and should never be used for a production environment.
