Requirement : .net framework 4, windows xp to windows 10
The 4.0 branch will be the last version compatible with windows XP (<3% of romcenter users are on xp).
Developments and fixes continue for romcenter 4 final release.
So far, I have improved stability and fix operation is also faster.
Some tricky bugs have been fixed as well.
Updating db to a new version is way faster by the use of a datapump tool instead of sql queries.
