    There are new drafts of Unicode specifications connected with IDNA and

        * UTS #46: Unicode IDNA Compatibility Processing
        * UTS #39: Unicode Security Mechanisms
        * UTR #36: Unicode Security Considerations

    The major changes include the following:


        * Major rework based on the UTC and editorial committee decisions.
          The text and specification are simplified considerably.
        * The FAQ section was separated from the document and rewritten as
          an independent FAQ page
        * Draft data files were restructured
        * Added a comparison table of IDNA2003, UTS46, and IDNA2008

    /NOTE: IDNA2008 is not final, and the draft UTS46 may undergo changes
    depending on the final form of IDNA2008/


        * The confusable data was revised to add data extracted from a
          comparison of font data from Windows and Mac
        * Additional mappings were also added, such as "rn" ~ "m"
        * The characters recommended for identifiers were updated based on
          UAX 31


        * Added new sections
              o 3.6 Secure Encoding Conversion
              o 3.7 Enabling Lossless Conversion to Unicode

    The public review period for these specifications ends on January 26, 2010.
