Highlights:

Four new encodings, contributed by Rony G. Flatscher (thanks!): ISO-8859-1 (alias: ISO8859-1), CP-437 (alias: CP437), CP-1252 (alias: CP1252), IBM-1047 (alias: IBM1047).
A lot of new documentation. Documentation, though, is still a work-in-progress.
A new ENCODE BIF.
A new OPTIONS DEFAULTSTRING NONE. Use it when other forms of OPTIONS DEFAULTSTRING causes problems (see the documentation for the RXU preprocessor for details).
A lot of bug fixes and small improvements.
