Hi everyone,
Would you prefer for us not to offer these public RC versions? Keep in mind that adopters of new cameras (e.g., Rebel T2i) would have to wait a few more weeks to get final support. That is, not having a public RC does not imply moving up the final release date.
We realize that there are many users who have one of the latest cameras (i.e., users who are eagerly waiting for a software update from us), and we also realize there are many users who have older cameras and don't care about these updates. Please understand that it is very difficult to please both groups simultaneously.
