[XeTeX] Release 0.93 is available

[Dalyoung]

Dear Jonathan,

I downloaded the release 0.93 and install it.
XeTeX, XeLaTeX, and XeTeX-ConTeXt are working perfectly.

Thank you so much for your efforts to solve rather very minor problems 
like mine. , I think that most of XeTeX users don't need this upgrade.

Because of your nice work(also Will, Adam, Gerben, and others), I am 
able to use various Korean fonts in my system with ease.

Thank you again.

Best regards,

Dalyoung
