We are working hard to finish version 0.9 of the mcScript compiler and Virtual Machine. The plan in to release version 0.9 of the compiler at the end of next month. Version 0.9 should be feature complete and I have added a document that describes the differences between 0.8 and 0.9. Later this year if version 0.9 matures we will bring out the first non-beta release.
Important improvements are support of Double and Long, Properties, Method overriding, Inheritance based polymorphism, Formatting, improved multi threading, Stopwatch class, faster compilations end more. Its all in the attached PDF.

Nice bed-time and week-end reading and please let us know if we miss any functionality that you think is important. Don't forget that this only related to the compiler and VM. Don't comment here on mcStudio or mcCloud because they are completely separated from the compiler and VM.
