Come the release of Koha 3.20 (towards the end of May), support for Debian 6 (squeeze) and Ubuntu 12.04 LTS (precise pangolin) will be dropped from the Debian packages. This won't affect Koha 3.18, which will continue to support these distros until it's no longer being released. This is due to the increasing difficulty of supporting features requiring modern OS infrastructure as more things are added to Koha. Essentially, backporting more and more libraries was becoming difficult and it's safer to upgrade the OS. Support for Debian 7 (wheezy) and Ubuntu 14.04 LTS (trusty) will remain for the next couple of years I expect. On the 25th of April, Debian's next version (8 (jessie)) will be released. As of right now, Koha packages may not work with it due to minor dependency issues. If you are planning to upgrade to that, keep an eye on: http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=13979 which will be coming to a release near you very soon I hope. -- Robin Sheat Catalyst IT Ltd. ✆ +64 4 803 2204 GPG: 5FA7 4B49 1E4D CAA4 4C38 8505 77F5 B724 F871 3BDF
