XSL support in various versions of Notes/Domino

Does anyone know if there were any changes to XSLT support between various versions of Notes/Domino (i.e. 7.x to 8.x).

I’m particularly interested to know if 8.x includes (or will include in future releases) support for XSLT 2.0 and/or XQuery.

Are there any differences between the Lotusscript and java implementations?
