0.2.0

• Major BC Break: method names for the Element interface have been renamed
  from serializeXml and deserializeXml to xmlSerialize and
  xmlDeserialize. This is so that it matches PHP's JsonSerializable
  interface.
• #25: Added XmlSerializable to allow people to write serializers without
  having to implement a deserializer in the same class.
• #26: Renamed the Sabre\XML namespace to Sabre\Xml. Due to composer magic
  and the fact that PHP namespace are case-insensitive, this should not affect
  anyone, unless you are doing exact string matches on class names.
• #23: It's not possible to automatically extract or serialize Xml fragments
  from documents using Sabre\Xml\Element\XmlFragment.

0.1.0

• #16: Added ability to override elementMap, namespaceMap and baseUri for
  a fragment of a document during reading an writing using pushContext and
  popContext.
• Removed: Writer::$context and Reader::$context.
• #15: Added Reader::$baseUri to match Writer::$baseUri.
• #20: Allow callbacks to be used instead of Element classes in the Reader.
• #25: Added readText to quickly grab all text from a node and advance the
  reader to the next node.
• #15: Added Sabre\XML\Element\Uri.

0.0.6

• Added: CData element.
• #13: Better support for xml with no namespaces. (@kalmas)
• Switched to PSR-4 directory structure.

0.0.5

• Added: baseUri property to the Writer class.
• Added: The writeElement method can now write complex elements.
• Added: Throwing exception when invalid objects are written.

0.0.4

• Fixed: The KeyValue parser was skipping over elements when there was no
  whitespace between them.
• Fixed: Clearing libxml errors after parsing.
• Added: Support for CDATA.
• Added: Context properties.

0.0.3

• Changed: Reader::parse returns an array with 1 level less depth.
• Added: A LibXMLException is now thrown if the XMLReader comes across an error.
• Fixed: Both the Elements and KeyValue parsers had severe issues with
  nesting.
• Fixed: The reader now detects when the end of the document is hit before it
  should (because we're still parsing an element).

0.0.2

• Added: Elements parser.
• Added: KeyValue parser.
• Change: Reader::parseSubTree is now named parseInnerTree, and returns either
  a string (in case of a text-node), or an array (in case there were child
  elements).
• Added: Reader::parseCurrentElement is now public.

0.0.1

• First alpha release
