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.
Version 0.9.9 was mostly a heavily optimized version of 0.9.8, with a few new features and an icon editor added.
Since each executable file took up considerable disk space for shared functions, Costa and most of its accessories were compiled to a single EXE. This also allowed for faster execution, since everything was already in memory during runtime. By heavily optimizing the code I managed to squeeze all accessories into an EXE file less than 165 KB in size, saving about 400 KB disk space. The desktop alone from 0.9.8 was 105 KB, so that was quite decent.
