Version 0.8-2

  * Changes to support libxml2-2.4.21 (specifically the issues with
    the headers and parse error regarding xmlValidCtxt). Thanks to 
    Wolfgang Huber for identifying this.

  * Ignoring R_VERSION now, so dependency is R >= 1.2.0

Version 0.8-1

  * Added an `attrs' argument to the xmlOutputBuffer and xmlTree
    functions for specifying the top-level node.

Version 0.8-0

  * xmlValue() extended to work recursively if a node has
    only one child. 

  * T and F replaced by TRUE and FALSE

Version 0.7-4

  * Support for Windows

Version 0.7-3

  * Documents without <DOCTYPE ..> are handled correctly.

  * Configuration tweak to set LD_LIBRARY_PATH to handle the case
    that the user specifies LIBXML_LIBDIR and it is needed to run the 
    version test.

  * Keyword XML changed to IO.

Version 0.7-2

  * Fix for printing XMLNode objects  to handle comments and elements 
    with name "text". Identified by Andrew Schuh.

Version 0.7-1

  * Minor fixes for passing R CMD check.

Version 0.7-0

  * Generating XML trees using internal libxml structures: 
     xmlTree(), newXMLDoc(), newXMLNode(), saveXML().

  * Support parsing HTML (htmlTreeParse()) using DOM.
     Suggestion from Luis Torgo.

  * Additional updates for libxml2, relating to DTDs.

Version 0.6-3

  * Installation using --with-xml2 now attempts to link against libxml2.so
    and the appropriate header files.

  * Use libxml's xml-config or xml2-config scripts if these are available.

Version 0.6
   
  * xmlDOMApply for recursively applying a function to each node in a tree.

Version 0.5-1

  * simplification of xmlOutputBuffer so that it doesn't put
    the namespace definition in each and every tag.

  * configuration changes to support libxml2-2.3.6
    (look for libxml2, check if xmlHashSize is available)

  * now dropping nodes if the handler function returns NULL.
    Updated documentation.

  * spelling correction in the documentation

Version 0.5
 * xmlOutputBuffer now accepts a connection.   

 * Fixes for using libxml2, specifically 2.2.12.
   Also works for libxml2.2.8

 * Enhanced configuration script to determine what features are available.
   
Version 0.4

 * `namespace' handler in xmlTreeParse is called when a namespace
   declaration is encountered. This is called before the child nodes
   are processed.

 * More documentation, in Tour.

 * xmlValue, xmlApply, xmlSApply, xmlRoot, xmlNamespace, length, names

 * Constructors for different types of nodes: XMLNode, XMLTextNode, XMLProcessingInstruction.

 * Methods for print(), subsetting ([ and [[), accessing the fields
   in an XMLNode object.

 * New classes for the different node types (e.g. XMLTextNode)

 * Event driven parsing available via libxml. Expat is not needed but
   can be used.

 * Document sources can be URLs (ftp and http) when using the libxml parser.

 * Examples for processing MathML and SVG files. See examples/ directory.

 * Examples for event driven parsing.



 * Class of result from xmlTreeParse is XMLDocument.

 * Comments, Entities, Text, etc. inherit from XMLNode
   in addition to defining their own XML<type> class.
