  3. new modifier @deterministic for "safe" functions /ext. functions that do not allow non-determinism in their behaviour;
  4. templates declarations now are also allowed in component type definitions;
  5. functions/altsteps may declare references to the known component types mtc/system;
  6. new predefined functions: for conversions between universal character/octetstring , the encoding/decoding of universal charstring, and a function to retrieve the hostid;
  7. operations on port and timer arrays allow to use and retrieve index of component arrays, port arrays, timer arrays (new @index modifier).
