http://www.unicode.org/review/Review period for the new item closes on July 27, 2011.
Please see the page for links to discussion and relevant documents. Briefly, the new issue is:
PRI #186 Word-Joining Hyphen
The Unicode Standard has different character properties for line-break and word-break behavior that reflect differences in behavior. The standard specifies that U+2011 NON-BREAKING HYPHEN disallows line breaks. The Unicode Technical Committee is currently considering whether this non-breaking behavior should be broadened to also affect word breaking behavior.
Details concerning this proposal are in the PRI itself:
