Ah, I think you did miss something - version 0.91 added a new feature  
to enable line-breaking based on Unicode character properties,  
tailored for a given locale (as there's no "universal" set of rules).

You can enable this by adding a couple of declarations at the start  
of a document, e.g.:

    \XeTeXlinebreaklocale "zh" % allow inter-character linebreaks  
according to Chinese locale
    \XeTeXlinebreakskip = 0pt plus 1pt % allow some stretch at such  
places, for justification

This is not turned on by default, as it will affect TeX's behavior  
(in minor and usually benign ways, it's true, but it would appear  
buggy to an unsuspecting TeX user).
