You may not notice much difference between this release and what you are used to. Behind the scenes the code has been significantly rationalised and improved, and it will be easier to maintain.
The game now responds much faster; it is quick enough that scores are recalculated from scratch on every move and there is no need for a ‘Rescore’ facility.
The Styles also respond better than they used to in varying zoom settings and across browsers (although cross browser perfection is not possible).
If you notice any issues, please let me know.
