We have had some challenges with the algorithms and UX in the patch we are working on (non-stop..), this has caused some long weeks of just coding.
It really sucks not to have time to give updates, but we want to give proper answers to people, and when you have your head chock full of advanced algorithms that are not working properly, that is a bit tricky.
Our community contact was supposed to be the fix for that - she has been hindered from starting her work, but luckily, she is in place today!
What is coming:
1) A new approach to polygon mapping that gives you unlimited polygons to work with. (100% done)
2) A new and clever solution to making geometric-like shapes, and make rough sculpting easier. (70% done - here is an early screenshot with edge bugs - don't judge! http://imgur.com/a/vX5ID )
3) A new approach to mirroring that includes radial symmetry (30% done)
4) Saving, undo etc for the new functionality (0% done)
Most of the work is in point 1) and 2) All in all, the version is about 70% done. There will be some hefty work in the coming time. Our new ETA looks like next week.
