A lot of minor bugs were corrected. Update if something
you need is not working, but watch out: the
escaping rules of mod-xslt expressions have changed.
Your media expressions in document that were already 
working under mod-xslt may not work anymore! Take
a look to the manual note "Since mod-xslt2 1.3.9", in
section "Choosing the stylesheet to use / xml-stylesheet 
and modxslt-stylesheet / Media Expressions / Strings".
