I have decided to make every previous version of Costa available for download, to preserve its history and to allow anyone interested in seeing how Costa has evolved to do so.
In the archive you will find a complete list of releases, with changelog for each version, as well as a screenshot.
It's a long list, with releases spanning nearly two decades.
Costa 0.9.3 was never officially released, but is available here for historic reasons. It had a lot of improvements over 0.9.2 that made it my personal favorite of the task-swapping editions. Sadly, the code suffered from bad planning and messy programming style. On the 19th of May, 2006 Costa 0.9.3 was canceled.
