I know 2013-2 was released, then pulled due to issues. I never saw an announcement about 2013-2 (2013-3?) being released.
The download page makes no mention of version or date that it was updated, only what the requirements are. I know that the version on the download page is the "most recent" version, but I can't tell if what I'm running (2013-1) is outdated or not without version numbers of some kind! Please consider putting SOMETHING on the download page to indicate which version of the software is currently being offered up.
In my wildest fantasies, an English changelog would be nice as well. If that's somewhere that I just haven't noticed, someone please point me to it.
EDIT: I downloaded and installed the file from the Downloads section. Turns out it's 2013-2. My point stands though, I shouldn't have to download the file and launch the installer to find out what version of the software it is.
