Hi there sent you an email and PM, see previous post 
Hi Mark,
After the G4 update, Antipodes stated that they would focus on software updates, but throughout 2025 no updates were released.
By the way, after registering I can’t see any indication that my K50 has received a G4 upgrade
There are no upgrades available currently, these will be released later in the year, if you click on the Upgrade Button in Circle it gives the current status.
We haven’t moved previous information over to Circle.
Circle is the beginning of a much improved and advanced system for support.
