Jsdom 5.0.1 发布，此版本主要有以下更新：
Fixed
document.cookie setter to no longer ignore null; instead it correctly
sets a cookie of "null". (Chrome is not compliant to the spec in this
regard.)
Fixed documents created with parsingMode:
"xml" to no longer get
"<html><head></head><body></body></html>"automatically
inserted when calling jsdom.jsdom() with no arguments. Fixed the innerHTML setter to no longer ignore undefined; instead it correctly sets the innerHTML to "undefined".
Fixed document.write to throw for XML documents as per the spec.
Fixed document.write to accept more than one argument (they get concatenated).
Fixed
document.write("") to no longer try to write
"<html><head></head><body></body></html>".
