The Koha development team is happy to announce the release of Koha3.4.0.

Koha 3.4.0 is a major feature release that contains major changes to underlying architecture (adoption of Template::Toolkit for templating) and performance enhancements (removal of item data from biblio records).

These changes, in addition to the inclusion of many new features, mean a lot of new strings for translators to translate.

For these reasons we recommend that people who are already running Koha in production delay their upgrade until 3.4.1, due May 22, to give the translatorstime to finish, and for the removing of item data to be streamlined. If you do wish to upgrade please make sure you read the UPGRADE section of the INSTALL document.

The development team would like to thank all the people who have made this release possible. Please take time to read the release notes.
