I just finished uploading 1.1 to Apple not 10 minutes ago, and barring any unusual rejections, it will be available any day now hopefully!
Here's what you can expect in 1.1:
* New special effects and graphics
* New Score Chains: keep making combinations to boost your score!
* 4 new awesome music tracks from the excellent Kevin MacLeod
* Improved game timing means less downtime after making a combination and faster gameplay!
* Improved ring selection indicator
* Improved load time and added spinner to indicate loading
* 3D lighting has been improved
* Cutscenes are now skippable
* Fixed some graphical glitches
I've also attached some screenshots you can have a look at
