We are currently running 5.0 U2 and are looking to get more up to date.
We don't necessarily want to jump right up to 5.5
Any convincing arguments why we should? Any why we shouldn't?
Is 5.4 stable enough to trust production, or did 5.5 address major concerns?
We of course can look at all the release notes for each version, but wanted to get the feeling of the community.
