Unicode 6.0.0 is out. See http://www.unicode.org/versions/Unicode6.0.0/ and press release http://www.unicode.org/press/pr-6.0.html
Please update Unicode support to that version.
For example the character Ɥ <U+A78D> has been added as the upper case of the previous ɥ <U+0265>
which would be useful for automatic redirection of http://en.wikipedia.org/w/index.php?title=%C9%A5 to http://en.wikipedia.org/w/index.php?title=%EA%9E%8D
