The release notes for Update #4 have appeared online, signalling the imminent arrival no doubt of the update itself.
The good news if you are using FireMonkey is that this is a significant update, including functionality for printing.
The bad news is that like update #1, this update is not an incremental patch but seemingly will require a full uninstall and reinstall.
For update #1 there were legal/licensing issues that made this necessary. What is the excuse this time I wonder ?
