The proposed update of UTS#10 Unicode Collation Algorithm (UCA) modifies the specification for certain edge cases (overlapping contractions), and tightens the requirements for well-formed collation element tables. The detailed descriptions of parametric tailoring options have been removed, and now refer to the corresponding section in LDML http://unicode.org/repos/cldr/trunk/docs/web/tr35.html#Collation_Settings. That section adds new explanations and definitions. There are a number of improvements, including additional examples, and some rearrangement of text. See PRI #223 http://www.unicode.org/review/pri223/

The data has been updated for the Unicode 6.2 beta review, and the associated CollationAuxiliary.txt file in CollationAuxiliary.zip http://www.unicode.org/Public/UCA/6.2.0/ now includes a description of the implicit fractional weight generation and the context syntax. For more details, see http://www.unicode.org/reports/tr10/tr10-25.html#Modifications.

There is also a proposed update of UTS #46 Unicode IDNA Compatibility Processing. The data has been updated for the Unicode 6.2 beta review, with minor changes to the text. See PRI #224 http://www.unicode.org/review/pri224/
