Alwil releases beta version of the application.
They make it available for users of this board.
(See the BETA section here)
Only after they (theirselfs) and we (as users here) have tested the application, and the problems (if there are any) are taken out, a 'final' version will be released to the public.
If you want to participate to the beta testing or not, is fully up to you.
My experience is that the beta versions are working.
Sure, there can be a little problem with them, but that is why they are beta and not final.
As I said before. read the BETA section on this board.
It will give you a pretty good idea on how Alwil deals with beta versions.
