GitHub and SourceForge are in-sync, so when I publish a release on GitHub it will be added on SourceForge.
I have started working on it again, see https://github.com/rodlie/cyan. Progress will be slow, but moving forward ;)
1.2.0 BETA binaries for Windows and macOS is now available.
Cyan 1.2.0 BETA will most likely be released tomorrow, note that Linux binaries are no longer supported (maintaining Win/OSX binaries is enough work), should not matter as Cyan is easy to build (on Linux/FreeBSD).
