This is the first of a few relatively small iOS 7 updates coming your way very soon.
Well, I say small. It looks like a small change but in terms of code it’s much more significant than you might imagine. I won’t bore you with the details but I will say that I managed to add “Send to iMessage” support as part of the upgrade. You might also notice a small tweak to the icon.
But something had to give and that is iOS 5 support. The old version should continue to work without problem.
One other thing: in previous updates I have had to remove some defunct URL shortening services. This represents the first significant release where that has not happened!
