SIXX now supports 'shape changed' class deserialization. Even if class
definitions are changed between SIXX file and the current image, you
can read the file via SixxShapeChangeReadStream.
- Safer Boolean reading
- Added a new option "SixxSettings>>useNCR"
- You can specify whether to write multi byte string by numeric
character references or not.
- Unicode string (de)serialization support (Squeak, VW)
