Latest version of Gajim is 0.11.4
A 0.12-alpha version is in test
If your distribution doesn't have the latest version you are advised to use the autopackage or the source tarball

Debian GNU/Linux

If you use Debian unstable do apt-get install gajim
A daily package from svn is also built. To use it, remove gajim (apt-get remove gajim), add this line to your /etc/apt/source.list:

and install it by doing apt-get install gajim-svn. You can get the GPG key of this package by installing gajim-dev-keyring package from the same repository. Just do apt-get install gajim-dev-keyring.

Under GNU/Linux

In order to download Gajim sources, here is what you have to do: You first have to install subversion (apt-get install subversion under Debian)
Then in a console, enter the following commands:

svn co svn://svn.gajim.org/gajim/trunk gajim

Install dependencies, and build Gajim. Please see the README (English) for details.

You can run Gajim by typing the following:

cd gajim and then ./launch.sh

Once you have the repository, you can update it periodicaly so it matches the latest version from the server with the following command:

svn update

Under Windows

You first have to install subversion for windows. In order to do that, download the binary here
Once subversion is installed, the commands are the same with those under GNU/Linux. Only difference is instead of launch.sh you run launch.bat. Enter them in an MS-DOS command line and you're done.
You can also use a graphical program like Tortoisesvn to get the latest Subversion version
To run Gajim, you need GTK Runtime Environment (Version 2.6.x or higher, 2.10.x is recommended) NOTE: GTK+ Runtime from gimp-win.sf.net will NOT work (libglade is missing), Python (Version 2.4 or higher, 2.5 is recommended), PyGTK for Windows (PyGTK with pycairo and pygobject), PySQLite and at last pywin32 extensions by Mark Hammond.

Daily Snapshots

Everyday on 01:00 (GMT+1 time) gz tarballs are produced from svn. You can use them if svn is broken for you at the moment. Here to get them.
