Changes:

### 1.2.3 / 2009-03-22

* Bugfixes

  * Fixing bug where a node is passed in to Node#new
  * Namespace should be assigned on DocumentFragment creation. LH #66

  * Builder methods take a hash as a second argument

## FEATURES:

* XPath support for document searching
* CSS3 selector support for document searching
* XML/HTML builder
* Drop in replacement for Hpricot (though not bug for bug)

Nokogiri parses and searches XML/HTML very quickly, and also has
correctly implemented CSS3 selector support as well as XPath support.

Here is a speed test:

Nokogiri also features an Hpricot compatibility layer to help ease the change
to using correct CSS and XPath.
