The new version is coming in a couple of days. (We're finishing the Mac version right now -- everything else is done).
To tell which version is out view the "[url=http://wyday.com/limelm/api/ta-changes/:3aak9nhl]Changes in TurboActivate[/url:3aak9nhl]" page. Or on the [url=http://wyday.com/limelm/api/:3aak9nhl]API page[/url:3aak9nhl] you'll see the version number in the download link. For instance, right now one of the links reads "Download TurboActivate [b:3aak9nhl]v2.13[/b:3aak9nhl] for Windows".
We're going to make an opt-in email list for people to be notified when new versions are released. However releasing this new version of TurboActivate has taken priority.
