On certain stores, the Linux (and OS X) packaging has changed, with contents unchanged, and required a slight version bump up to 1.0.1 as well. Most stores don't really have any good way for me to revision packaging changes. I would just append or prepend a full date, if I had my way, but on certain stores that convention is not possible for a couple of reasons.
We'll get a nice blank slate across all platforms hopefully when we push 1.1, I would think.
