Well, at the moment we are on 1.7.7, with the next version in Beta for windows and Linux...
We are only 'stalled' on Mac OS X and Solaris (which might be a dead OS in reality)
You kinda missed telling us what OS you are on -- and you posted in the Windows OS forum...
Please fix your profile in your User Control Panel to let us know your OS (and version) plus the XAMPP version (1.7.3)
Good Luck
