regarding my statement "Release Candidate is a
version in which there are neither errors nor changes pending that the
developers would know of at the date of publishing" and its relevance to the status of the coming beta:
Currently, there are errors known to you, at least the broken mouse wheel support, unless you have fixed it and forgotten to tell me. Also, I have already collected one or two not yet published bugs ready for the second batch, discovered by me accidentally, although I have not yet started heaving testing for the second batch.
So there are errors known and there will be many to come. If there will be only few bugs in the coming beta, showing I was mistaken, I will send symbolic 30€ to any european bank account you name ;).
