Thanks normis for quick reponse. It is obvious for me that those releases are not intended to be used in production. I would like to have the possibility to download them only for testing reasons (in my lab environment).
Just one more thing, I'd like to know. I've been using your products since many years, but I am new to the forum and not familiar with ROS development process. What should I do if I will find a bug in the RC/development release. Should or write to support or create new topic here?
