This year Kolab Systems has a very special Christmas present for you: The release of the Kolab server 2.3 alpha. A little late, but good things take time.
This release introduces new features like synchronization of mobile devices with kolab-z-push or modular packaging of the kolab-webclient, updates of many important components and tons of bug fixes. Detailed information about the changes are listed in
The release notes may be incomplete. They should cover all changes, but I will review them before the 2.3 final release just to be sure.
Upgrading from 2.2.4 should be straightforward, but make sure you follow the upgrade instructions in http://files.kolab.org/server/release/kolab-server-2.2.4/sources/1st.README
Documentation and OpenPKG packages are available from http://files.kolab.org/server/alpha/kolab-server-2.3-alpha/ as shown on http://kolab.org/download.html.
As soon as they have synced, you can also use the the mirrors listed on http://kolab.org/mirrors.html
All files updated since 2.2.4 are available in the directory server/development-2.3/20101224-since-20100629/
You can check the integrity of the downloaded files by importing our file distribution key and verifying the OpenPGP signature and SHA1 checksums:
$ gpg --keyserver pgp.mit.edu --recv-key 0xC43E1A3E
$ gpg --verify SHA1SUMS.sig
$ sha1sum -c SHA1SUMS
Binary packages for Debian GNU/Linux 5.0 (lenny/stable) on x86 platforms can be found in the ix86-debian5.0 directory next to the sources.
Support for Debian GNU/Linux 4.0 (etch/oldstable) was dropped because it is no longer supported by Debian ether.
Remember: This is an alpha release. It is for testing and evaluation only and likely contains bugs. DO NOT use it in productive environments!
