Personally i use 6.2.5 and anyone can use it, but there may be bugs since this version is currently under developing. This is the reason while the client currently says 6.1.8 is up2date. If 6.2.x is not being developed more and the last version showed no bugs for some time, this version will be the stable one and clients will be notified. It’s likely that 6.3.x will be released at this time.
Otherwise all “normal” users would have to update the software very frequently.
