Well, in our rush to get out a version with support for Events, we let a few bugs slip in. So I've just released a true bug-fix release. If you have an empty 'Events' album on your gallery, updating Pomoto and clicking 'Publish' will get rid of it. This release should also fix the problem of giving false warnings about publishing without any photos selected. Sorry about those... nothing critical, but annoying nonetheless.
As before, just open Pomoto or click 'Check for Updates...' from the Pomoto menu.
