CHANGELOG

• Added PHPUnit constraints: CrawlerSelectorAttributeValueSame, CrawlerSelectorExists, CrawlerSelectorTextContains`` andCrawlerSelectorTextSame`
• Added return of element name (_name) in extract() method.
• Added ability to return a default value in text() and html() instead of throwing an exception when node is empty.
• When available, the html5-php library is used to
  parse HTML added to a Crawler for better support of HTML5 tags.

4.2.0

• The $currentUri constructor argument of the AbstractUriElement, Link and
  Image classes is now optional.
• The Crawler::children() method will have a new $selector argument in version 5.0,
  not defining it is deprecated.

• All the URI parsing logic have been abstracted in the AbstractUriElement class.
  The Link class is now a child of AbstractUriElement.
• Added an Image class to crawl images and parse their src attribute,
  and selectImage, image, images methods in the Crawler (the image version of the equivalent link methods).

2.5.0

• [BC BREAK] The default value for checkbox and radio inputs without a value attribute have changed
  from '1' to 'on' to match the HTML specification.
