We already think YetiShare is a pretty good file hosting script, although we want to make it better, the best out there!
We therefore run proactive release schedules, generally every few months with new features and bug fixes. The YetiShare RFCs on our forum enable our users to submit ideas for the next release. All RFCs are reviewed for inclusion into the core codebase on each development round.
You can see details of our previous releases on the release history pages.
