I just discovered I've been running the last 1.0.1 sneakpeek release for 10 days after the formal 1.0.1 release (time-stamped on March 4).
My manual Check for Update kicked off a self-update to 1.0.1.
I found this in the automatic Release Notes:
"Software Update will now only show you builds on the same track that you are running. So, if you want to see sneakypeek builds, you'll need to manually download one sneakypeek build main OmniFocus site."
It makes sense for the sneakypeek track to be a personal decision. But it seems jumping from sneakypeek to formal should be automatic. Did I simply miss the update notice on March 4?
