I am hesitant to give another estimate, at this time. As stated above, we were shooting to have this out already, and we are trying to get it out as soon as we can.
During our planned development efforts we saw several unanticipated areas of improvement. These improvements will make things much better, across the board, and enhance our ability to fix, refine, and add features in the future. It is an investment we felt we needed to make, despite the release delays it would cause. We just want to do it right, and this stuff is not trivial.
We are trying to go as fast as we can and great progress is being made every day. That being said, I completely understand if the wait is too long for some folks and there is a need to look elsewhere to address a particular use case, like backup.
As always, thanks for your patience and support.
