In the FAQ area there is an article regarding the download links to the desktop apps for Windows and Mac. Unfortunately this is closed for comments. That's why I'm writing here. The versions linked “over there” are no longer up to date at all.
The latest versions can be found here:
Windows:

Mac:

Maybe the posts could be linked etc... Nothing is worse than finding outdated information in the FAQ.
