upgrading to 1.12.x

i just noticed that there is no mention in the documentation of any tips for upgrading from 1.11.x to 1.12.x. does that mean that there are no specific changes needed between these minor revision numbers?

as an aside, i couldn't get 1.12.x to upgrade my 1.11.x install on nginx here. i ended up stepping through the upgrade file and putting in debug statements.. then out of nowhere it just worked. i have no idea why it failed before the debug statements were put in. i suspect this may be an issue that is limited to my pc here in some way.. but don't know for sure.
