DMDirc has now entered Feature Freeze for the 0.5 release (for more information about our release cycle, see this blog post).
New for this release we have decided to build Release Candidate builds approximately every day. Release Candidate builds are just like the final release: they are installed using the new installer, and they are feature complete for 0.5. Their purpose is help discover/iron out any last bugs before we tag and release 0.5 into the wild and begin on 0.6.
Once we get an RC build with no apparent bugs, we will release 0.5 :)
