WHAT IS KOLAB?
Kolab is a personal information management solution, also referred to as groupware. It can provide and manage your information including email, address books, calendars and tasks.
The Kolab server acts as the central information repository and thanks to its uniquely powerful design can host up to tens of thousands, theoretically even hundreds of thousands of users.
All these users can freely share email, address books, calendars and/or tasks with all, some, or none of the other users. This allows Kolab to provide the support base for a wide variety of activities, such as coordinating appointments, working on common projects and ensuring consistency in customer contact.
The new Kolab 2.3.0 server includes a lot of new features, namely:
- Z-push synchronization for mobile devices
- A reworked webadmin
- The possibility to have multiple accounts with the same name.
- Modular packaging of the webclient
- Many updated core components
- Tons of bug fixes
A detailed list of changes is available here
Because of the changes in LDAP, upgrading from 2.2.4 is not trivial and requires manual intervention. Please make sure you read and follow the upgrade instructions in http://files.kolab.org/server/release/kolab-server-2.3.0/sources/1st.README
Binary packages for Debian GNU/Linux 6.0 (Squeeze/stable) and 5.0 (Lenny/oldstable) on x86 platforms can be found next to the sources.
Support for Debian GNU/Linux 4.0 (etch/oldstable) was dropped because it is no longer supported by Debian ether.
As soon as they have synced, you can also use the the mirrors listed on http://kolab.org/mirrors.html
You can check the integrity of the downloaded files by importing our file distribution key and verify the OpenPGP signature and SHA1 checksums:
$ wget https://ssl.intevation.de/Intevation-Distribution-Key.asc
$ gpg –import Intevation-Distribution-Key.asc
$ gpg –verify SHA1SUMS.sig
$ sha1sum -c SHA1SUMS
This release marks the end of a long development cycle. After over 2 years, the master and the stable branch are (more or less) in sync again. We
introduced many new features and fixed a large number of bugs. We tested the release intensively but due to the massive code changes, we might have missed something or even introduced new bugs.
Before you use this release in a critical environment, we’d like you to test it. Please report any problems you encounter in our bug tracker: https://bugzilla.kolabsys.com/
Depending on the number and severity of bugs, we will issue an updated release soon. We already have a number of fixes in the queue such as the today’s Z-push 1.5.2 release, so Kolab 2.3.1 will come soon.
I’d like to thank a few people for their help, namely and in no particular order:
– Paul and Georg, for giving me the chance to work on a great project like Kolab
– Bernhard for his coordination
– Thomas and Sascha for their support, especially during this week
– Bogo for the awesome new look of the webadmin
– Jeroen for his input and providing me the infrastructure I need
– Gunnar for responding so fast to the issues we spotted
Without these people the Kolab Server 2.3 would not be possible. Thank everybody for your hard work!
