The latest official beta version is 1.25. which is also available for Mac under:
http://forums.stantondj.com/files/SCS3_DaRouter1.0.25.dmgHowever the version of DaRouter has almost nothing to do with the software you want to use it for. Therefore you have to check the Presets sub-forum and load the appropriate .tsi file for traktor pro and the .bmte file for DaRouter depending on which setup you are using.
The new beta 1.26 isn't official but already uploaded on the server. So we found a way to download it (see my first post in this thread)
Bit confusing but I hope that helps
