Upgrading to Omeka 1.2.1

I'd like to upgrade to the latest version of Omeka. However, I don't want to overwrite any of the files that I've worked on so far. Could you tell me which files I should upload and which files I should stay away from (because the would overwrite my development)? I went to the Release Notes page to see if there was any information there but it was empty.

Hi Jeff,

The changelogs and release notes are updated now:


Be sure to back up your database and copy your installation any time you upgrade, so that you have a complete back up. And follow the instructions for upgrading: http://omeka.org/codex/Upgrading
