The Vienna team is happy to announce a public beta version of the upcoming Vienna 2.4 release. You can download the beta version from SourceForge at Vienna build 2400. An English-only version can be downloaded as well. Once you start using the beta, future beta versions of 2.4.0 as well as the final release will appear in Vienna's built-in Check for Updates.


Vienna 2.4 requires Mac OS X 10.5 Leopard or higher to run. Sorry, we can no longer support Mac OS X 10.4 Tiger.

Pre-release software

The Vienna 2.4 beta version is pre-release software, and it may contain bugs. If you discover a bug, please create a new topic here in the Vienna forum and report the bug to us. Some tips for writing good bug reports can be found at For safety, we recommend that you back up your files before running the beta version. Vienna's files are located at "~/Library/Preferences/" and "~/Library/Application Support/Vienna".

Database upgrade

On the first launch, Vienna 2.4 will upgrade your database. Depending on the size of your database, the upgrade may take some time, so please be patient on first launch. Because of the database upgrade, we don't recommend that you switch back and forth between Vienna 2.4 and Vienna 2.3.
