  The changes were the following:

- Managed code now needs to keep a reference to delegates passed to unmanaged
  code, otherwise they will be freed. For more info an possible solutions, see


- Strings inside structures/arrays passed to managed code are now freed after
  the call.

- Memory returned by unmanaged code in some form (return value, changed 
  byref parameter etc) is now freed after it has been converted to managed data.

Other than this, things should work the same, but there could be bugs in the
new code so beware.
