Could you or someone provide a list of future version numbers you are intending to use?
0.4.0 : Out real soon (0.4.0 release candidate 2 binaries are available on sourceforge now)
0.4.1 : I'd give about a 80% chance of happening (major bug or security problem found in 0.4.0)
0.4.2 : I'd give about a 20% chance of happening (major bug or security problem found in 0.4.1)
0.5.0 : Will be the Qt release.
Beyond that... who knows?
