Yes, it has been significantly changed: we switched from open source CSS Parser Project library to our own CSS parser/cascading engine. Obviously the issue is there.

Even if the issue not in the new CSS parser, there is a lot of adjustments in the main converter code.
An HTML code sample (incl. its CSS resources) which 100% throws an exception on your site would help a lot to determine a problem reason.
(I am afraid, the blank HTML is not the right sample – the exception is thrown by CSS parsing and the HTML does not refer to any CSS resources)
