Hi,

We have upgraded SIXX to 0.2. The new version is available for all
platforms (Squeak, VisualWorks, and Dolphin Smalltalk).

SIXX 0.2:
http://www.mars.dti.ne.jp/~umejava/smalltalk/sixx/index.html
(Also loadable from SqueakMap).
http://map.squeak.org/package/60663648-6b83-4b61-9f06-e58c33565d75/autoversion/5

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.

Other features:
- 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)
- Added more hook methods for customizing serialization/deserialization.

More details are described here:

Enjoy!
