Yeah, the description in Google Play was just the same as last update. Even that was poor - "Lots of bug fixes" hardly inspires confidence.
Compared to say... Texta which I just installed... and for every release they have notes which tell you what got fixed, and version numbers, and ... well, all the things you'de expect.
But... maybe it's just because they are in Beta, and probably desperately trying to get it released. Still - getting the process right in the first place would be a good idea in my opinion. (being a software development PM an all)
