Is this thread strictly related to RC5 only or I can ask questions related to RC6 also?

If I can ask questions related to RC6 also, then can I ask questions related to everything RC6 (on sqlite, on cairo, on modules like 'FSO, Crypt etc.', on widgets, etc. except on webview2)? I am not including webview2 since I am aware of the separate thread for it (started by Olaf) and I have always posted questions related to webview2 therein only.

Any guidance on the above from anybody most welcome.

Kind Regards.
