Files for DuckClient version 5.7 are now available in the downloads folder. Those of you using the ChromeOS version already got the update yesterday.
I highly recommend that anyone using the standalone version update to this release, because it fixes a bug that crashes the entire client when re-spawning a trigger window.
There are also new options for exporting your settings, and an improved font selection UI in the standalone version.
The source code for DuckClient is now available as a Mercurial repository at http://duckclient.com/repo. The license is 2-clause BSD.
