This release adds the much-requested Zebra support and updates Koha to 3.0.5. You dont need to configure anything, as I have pre-configured zebra daemons to start automatically and added the crontab for indexing, which will be there as soon as the Live CD starts up. You do need to select to use Zebra when you go through the web-installer wizard, as well as selecting Marc21″ when asked.
So go ahead check out the project page and give it a whirl
