Hi, I'm planning to release 5.6.0 from RC4 if nothing serious comes up, so this is just a heads-up: if you think that there is some fix, which should make into the 5.6.0 final (which isn't in RC4) or if you think that there is some blocker issue which should be solved before the 5.6.0 final release, please drop me an email just to be sure.
