Good question. Are there any upgrades scheduled from the developers?
That also is a good question. I am going to go check the website and see if it has anything to say about that. No one seems to have an answer and looking
around on this forum people seem to be making alot of their own mods and customisations without concern for this. I guess I just have to do the grunt work of keeping track of what files I have modified so in the event of an upgrade we can merge (should be fine without to heavy modification.)

is about the current release osTicket v1.6 RC4
While osTicket 1.6 RC4 is considered close to stable release of version 1.6, we hope to release v1.6 final in the near future following community feedback.
