You know that in the open source world you don't have to make a stable release just to share your code and let others try it out or even help to find bugs and improve it?
Certainly, but celestia.Sci
is a very complex program. Besides developing new code for a host of new features (such as Gravitational Lensing), we simply don't have the menpower to answer in addition all the questions that people will surely have initially, i.e. in a too early stage of going public.. Don't forget that celestia.Sci will come for THREE operating systems in 64bit format throughout. Many unexperienced people will need help in building and installing such involved software. Hence plenty of instructions / manuals will still have to be written etc.
Sorry for keeping you waiting...
