1.64
   - fix reconcilation of the "xml" namespace [rt.cpan.org #26450] 
   - make tests pass with libxml2 2.9.29 - PI regression tests now
     accept "" as data of an empty PI [rt.cpan.org #27659]
   - strip-off UTF8 flag with $node->toString($format,1) for consistent
     behavior independent on the actual document encoding
   - fix in XML::LibXML::Reader::nextSiblingElment
   - fix synopsis for XML::LibXML::Reader
   - skip tests that require Encode module if not available (perl 5.6)
   - finally removed the iterator() method deprecated since 1.54

   - make XInclude reflect parser flags
   - documentation fixes
   - better namespace reconciliation implemented by Tim Brody
   - $doc->toString always returns octets
   - $doc->actualEncoding returns UTF8 if no document encoding is declared
     (unlike $doc->getEncoding, which returns undef)
 
1.62
   - interface to libxml2's pull-parser XML::LibXML::Reader
     (initiated by Heiko Klein)
   - make error messages intended to the user report the line of the
     application call rather than that of the internal XS call
   - XML::LibXML::Attr->serializeContent added (convenience function)
   - fix getAttributeNode etc. w.r.t. #FIXED attributes (as well as some
     cases with old buggy libxml2 versions)
   - warn if runtime libxml2 is older than the one used at the compile time
   - if compiled against libxml2 >= 2.6.27, new parse_html_* implementation is used
     allowing encoding and other options to be passed to the parser
   - DOM-compliant nodeNames: #comment, #text, #cdata, #document, #document-fragment
   - toString on empty text node returns empty string, not undef
   - cloneNode copies attributes on an element as required by the DOM spec

1.61

     obey wildcards '*', getChildrenByLocalName was added.
   - XML::LibXML::XPathContext merged in
   - many new tests added
   - the module should now be fully compatibile with libxml2 >= 2.6.16
     (some older versions compile but have problems with namespaced attributes)
   - threads test skipped by default
   - documentation updates (namely DOM namespace conformance in XML::LibXML::DOM)
   - added setNamespaceDecl{URI,Prefix}
   - get/setAttribute(NS)? implementation made xmlns aware
   - all sub-modules have the same version as XML::LibXML

1.60
   - getElementsById corrected to getElementById and the old name kept
     as an alias. Also re-implemented without XPath for improved
     performance
   - DOM Level 3 method $attr->isId() added
   - make {get,set,has}Attribute(Node)? methods work with full
     attribute names rather than just localnames.
     (Although DOM Level 3 is not very clear about the behavior of
     these methods for an attributes with namespaces, it certainly
     does not imply that getAttribute('foo') should return value of a
     bar:foo, which was the old behavior.)
   - added publicId and systemId methods to XML::LibXML::Dtd

1.59
   - new parser and callback code (Christian Glahn)
   - new XML::LibXML::InputCallback class
   - many bug fixes (including several memory leaks)
   - documentation and regression fixes and enhancements
   - Perl wrappers for parse_html_*

   - faster getChildrenByTagNameNS implementation
   - remove the SGML parser code no longer supported by libxml (Michael Krll)

1.58

     random several segmentation faults on document fragments.
   - added NSCLEAN feature to the parser interface (bug 4560)
   - minor code cleanups
   - updated libxml2 blacklist.
   - fixed croak while requesting nodeName() of CDATA sections (bug 1694).
   - more documentation updates

1.57
   - added cloneNode to XML::LibXML::Document
   - include Schema/RelaxNG code only with libxml2 >= 2.6.0 (to support old libxml2)
   - applied patch to example/cb_example.pl (bug 4262)
   - fixed insertBefore/insertAfter on empty elements (bug 3691)
   - more DOM conformant XML::LibXML->createDocument API (by Robin Berjon)

   - improved support for importing DTD subsets
   - fixed DTD validation error reporting problems with libxml2-2.6.x
   - fixed compilation problems with libxml2-2.6.x
   - fixed XML::LibXML::Number to support negative numbers
   - added XML Schema validation interface (XML::LibXML::Schema)
   - added XML RelaxNG validation interface (XML::LibXML::RelaxNG)
   - Michael K. Edwards' patch applied with some amendments from Petr Pajas:
     * add debian build files (I added SKIP_SAX_INSTALL flag for
       Makefile.PL and changed the patch so that it doesn't disable
       sax parser registration completely by default, and rather made
       debian build use this flag)
     * general cleanup (use SV_nolen, etc.)
     * SAX parsers cleanup
     * general error reporting code cleanup/rewrite, try preventing 
       possible memory leaks
     * recover(1) now triggers warnings (disable with $SIG{__WARN__}=sub {})
       (fixes bug 1968, too)
     * slighlty more strict parse_string behavior (now same as when
       parsing fh, etc): e.g. parse_string("<foo:bar>"), i.e prefix without 
       NS declaration, raises error unless recover(1) is used
     * documentation fixes/updates
     * slightly updated test set to reflect the new slightly more strict
       parsing. 
   - fixed default c14n XPath to include attributes and namespaces (Petr Pajas)
   - make libxml2's xmlXPathOrderDocElems available through a new
