Turns out that we already have listed 8 Fix Packs for K2 Five...
Either the Develpment is moving to light speed or is just very buggy and they try to quick patch bunch of things, but from the page links:
To obtain the latest Fix Pack installer, please contact your regional K2 support center.
Really... not only need to make sure you contact K2 Support Center, there is no easy access to the patches..
Don't plan to do this on a Fri night, might need to wait until Mon to get the Fix Packs.
