This release has a new, brighter interface. It has a new peripheral AGDP (Auxiliary General Data Processor) that does floating point arithmetics and block operations extremely quickly (compared to doing it the manual way). The assembler is less strict about cases and has a few new tricks. There are several new instructions for improved debugging, address comparison, and atomic swapping.
The biggest change is the new and almost completely rewritten assembler (based on flex/yacc). It comes with a new and clearer syntax, inline arithmetic, variables, and a whole new level of stability. Interrupt queuing has been reworked, and behaves a lot more predictably. Vector and raster graphics have been added. Support for a virtual floppy drive of sorts has also been added, as well as support for a computer mouse. Output is compressed with zlib, granting in many cases a hundredfold size reduction of the memory images read and written by Tunguska. There are some bugfixes.
