Quoting Nathaniel Catchpole <catch56@googlemail.com>:
The only reason to upgrade from 5.x to 5.latest-stable would be if there's been schema changes in a minor version. This is very rare, but sometimes necessary - however it's easy to check by comparing system.install between 5.0 and 5.18 to see if any new hook_update_N() has been added.
Really? Then why is it documented practice? <quote reference="http://drupal.org/upgrade/"> 1. Upgrade to the latest minor version in the major version you're currently on (e.g. if you are on 5.5 and want to upgrade to 6.10, and there is a 5.12 version out, upgrade to 5.12 first). </quote> -- Earnie -- http://r-feed.com/ -- http://for-my-kids.com/ -- http://www.4offer.biz/ -- http://give-me-an-offer.com/
