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.
The most notable change of 1.6.0 is the addiction of EGA support. Now, Costa will run on computers with an Enhanced Graphics Adapter with at least 64 KB memory, broadening the range of computers on which Costa is supported. The new EGA mode is also considerably faster on older machines (pre-1990).
