So that would be my tip … unless you're experiencing problems on
5.3 that were resolved in 5.4, just hang fire on the effort of upgrading until a patch or
two have gone out on 5.5.
How far behind the latest release do folks usually lag? I'm just
curious as I'm used to trying to stay current to "get the pain" over
with on stuff like that, but of course that isn't always possible.
