== Bugfixes and improvements ==

- All type combinations in equality test ("=" and "~") shall now
  work properly.

- Deep features now work for all types without any exceptions.

- The garbage collector has been reworked completely. Before,
  expandeds which contained references could create memory
  leaks. Now all temporaries which are references or contain
  references into the heap are registered. Therefore no live
  object (i.e. reachable directly or indirectly) can be reclaimed
  by the garbage collector.

- Bug: In some cases a conversion procedure did not work
  properly. All cases with reference types went well. However
  conversion from or to expanded types where the entity size of
  the source type is different from that of the target type did
  not work well.

- Bug: Nested exceptions (raised exception within exception
  handling) created problems, if the exception handler is the
  direct receiver of the original exception and the second
  exception.

- Virtual machine on big endian and little endian machines: Some
  operations had not been designed properly to work on big and
  little endian machines. The virtual machine has been reworked
  to be insensitive to the endianness of the machine.
