The header in allkeys.txt states: version 3.1.1. There are 1016 characters defined in Unicode 3.2, which are not mapped (yet). See: http://www.unicode.org/Public/3.2-Update/DerivedAge-3.2.0.txt I believe the version and repertoire of the Unicode Collation Algorithm (UCA) will be synchronized with versions of the Unicode Standard starting with Version 4.0.
