To my knowledge there hasnt been any beta-testing group?. Select betatesters by most logins over a period of time so we ensure that the released versions are bullitproof. The current relase is very critical.
2) Make version optional
We have clients that cant roll out 5.0 because they cant roll software out when they want because of internal IT processes. Suggesion: make older versions downloadable and make sure they still work. New segment cant be used in 4.7 which means that updating of reports very hard for some companies. I understand that this i not easy but very import if RB shall be considered an import part of an enterprise paltform.
