I also have a question? When i upgrading eZ publish from version 3.4.1 to 3.4.2 and 3.4.2 to 3.4.3 i must run the update scripts?
When updating i absolutely must run update scripts for every update? Is it enought to update files and database?
You should not have to run any upgrade scripts upgrading from 3.4.0 -> 3.4.4.
Upgrading from 3.3.x to 3.4 is another matter though. The upgrade process is documented here: http://ez.no/ez_publish/download/changelogs/ez_publish_3_4/upgrading
