rvest 0.3.2

• Fixes to follow_link() and back() to correctly manage session history.
• If you're using xml2 1.0.0, html_node() will now return a "missing node".
• Parse rowspans and colspans effectively by filling using repetition from
  left to right (for colspan) and top to bottom (rowspan) (#111)
• Updated a few examples and demos where the website structure has
  changed.
• Made compatible with both xml2 0.1.2 and 1.0.0.

rvest 0.3.1

• Fix invalid link for SSA example.
• Parse <options> that don't have value attribute (#85).
• Remove all remaining uses of html() in favor of read_html() (@jimhester,
  #113).

rvest 0.3.0

• rvest has been rewritten to take advantage of the new xml2 package. xml2
  provides a fresh binding to libxml2, avoiding many of the work-arounds
  previously needed for the XML package. Now rvest depends on the xml2
  package, so all the xml functions are available, and rvest adds a thin
  wrapper for html.
• A number of functions have change names. The old versions still work,
  but are deprecated and will be removed in rvest 0.4.0.
  • html_tag() -> html_name()
  • html() -> read_html()
• html_node() now throws an error if there are no matches, and a warning
  if there's more than one match. I think this should make it more likely to
  fail clearly when the structure of the page changes.
• xml_structure() has been moved to xml2. New html_structure() (also in
  xml2) highlights id and class attributes (#78).
• submit_form() now works with forms that use GET (#66).
• submit_request() (and hence submit_form()) is now case-insensitive,
  and so will find <input type=SUBMIT> as well as<input type="submit">.
• submit_request() (and hence submit_form()) recognizes forms with
  <input type="image"> as a valid form submission button per
  http://www.w3.org/TR/html-markup/input.image.html

rvest 0.2.0

New features

• html() and xml() pass ... on to httr::GET() so you can more
  finely control the request (#48).
• Add xml support: parse with xml(), then work with using xml_node(),
  xml_attr(), xml_attrs(), xml_text() and xml_tag() (#24).
• xml_structure(): new function that displays the structure (i.e. tag
  and attribute names) of a xml/html object (#10).

Bug fixes

• follow_link() now accepts css and xpath selectors. (#38, #41, #42)
• html() does a better job of dealing with encodings (passing the
  problem on to XML::parseHTML()) instead of trying to do it itself
  (#25, #50).
• html_attr() returns default value when input is NULL (#49)
• Add missing html_node() method for session.
• html_nodes() now returns an empty list if no elements are found (#31).
• submit_form() converts relative paths to absolute URLs (#52).
  It also deals better with 0-length inputs (#29).
