The main changes in the 0.4 release are (a) a big upgrade to the Rexx tokenizer, and (b) a complete rewrite of rxu.rex, the Rexx Preprocessor for Unicode, to take advantage of the improvements in the tokenizer.

To know more about the upgraded tokenizer, please refer to its readme file. Changes to the Rexx Preprocessor for Unicode are internal, and should not affect its functionality. If at all, you should find that the new version is more smooth and stable.
