You should upgrade to 5.0.18; there was a security fix that was addressed as a hotfix in 5.0.16 and then rolled into 5.0.18.
Personally although I'm tempted by some of the features/bugfixes in 6.0, I'm wary of some of the problems I've seen reported. Depending on when things are released I think it's likely I'll wait for 6.0.1, going to 5.0.19 in the interim. |
