  • tried to fix as much as possible DTD validation and namespace related problems
  • output to a given encoding has been added/tested
  • lot of various fixes

2.0.0: Apr 12 2000

• First public release of libxml2. If you are using libxml, it's a good idea to check the 1.x to 2.x upgrade instructions. NOTE: while initially scheduled for Apr 3 the release occurred only on Apr 12 due to massive workload.
• The include are now located under $prefix/include/libxml (instead of $prefix/include/gnome-xml), they also are referenced by

  #include <libxml/xxx.h>

  instead of

  #include "xxx.h"

2.0.0beta: Mar 14 2000

• This is a first Beta release of libxml version 2
• It's available only fromxmlsoft.org FTP, it's packaged as libxml2-2.0.0beta and available as tar and RPMs
• This version is now the head in the Gnome CVS base, the old one is available under the tag LIB_XML_1_X
• This includes a very large set of changes. From a programmatic point of view applications should not have to be modified too much, check the upgrade page
• Some interfaces may changes (especially a bit about encoding).
• the updates includes:
  • fix I18N support. ISO-Latin-x/UTF-8/UTF-16 (nearly) seems correctly handled now
  • Better handling of entities, especially well-formedness checking and proper PEref extensions in external subsets
  • DTD conditional sections
  • Validation now correctly handle entities content
  • change structures to accommodate DOM
• Serious progress were made toward compliance, here are the result of the test against the OASIS testsuite (except the Japanese tests since I don't support that encoding yet). This URL is rebuilt every couple of hours using the CVS head version.

1.8.7: Mar 6 2000

• This is a bug fix release:
• It is possible to disable the ignorable blanks heuristic used by libxml-1.x, a new function xmlKeepBlanksDefault(0) will allow this. Note that for adherence to XML spec, this behaviour will be disabled by default in 2.x . The same function will allow to keep compatibility for old code.
• Blanks in <a> </a> constructs are not ignored anymore, avoiding heuristic is really the Right Way :-\
• The unchecked use of snprintf which was breaking libxml-1.8.6 compilation on some platforms has been fixed
• nanoftp.c nanohttp.c: Fixed '#' and '?' stripping when processing URIs

1.8.6: Jan 31 2000

• added a nanoFTP transport module, debugged until the new version of rpmfind can use it without troubles

• a Push interface for the XML and HTML parsers
• a shell-like interface to the document tree (try tester --shell :-)
• lots of bug fixes and improvement added over XMas holidays
• fixed the DTD parsing code to work with the xhtml DTD

• Fixed bugs in xmlNewNs()

1.8.1: Dec 18 1999

• a problem in one of the core macros IS_CHAR was corrected
• fixed a bug introduced in 1.8.0 breaking default namespace processing, and more specifically the Dia application
• fixed a posteriori validation (validation after parsing, or by using a Dtd not specified in the original document)
• fixed a bug in

1.8.0: Dec 12 1999

• cleanup, especially memory wise
• the parser should be more reliable, especially the HTML one, it should not crash, whatever the input !
• Integrated various patches, especially a speedup improvement for large dataset from Carl Nygard, configure with --with-buffers to enable them.

• Lots of HTML improvement
• Fixed some errors when saving both XML and HTML
• More examples, the regression tests should now look clean
• Fixed a bug with contiguous charref

1.7.3: Sep 29 1999

• snprintf was used unconditionally, leading to link problems on system were it's not available, fixed

1.7.1: Sep 24 1999

• The basic type for strings manipulated by libxml has been renamed in 1.7.1 from CHAR to xmlChar. The reason is that CHAR was conflicting with a predefined type on Windows. However on non WIN32 environment, compatibility is provided by the way of a #define .
• Changed another error : the use of a structure field called errno, and leading to troubles on platforms where it's a macro

1.7.0: Sep 23 1999

• Added the ability to fetch remote DTD or parsed entities, see the nanohttp module.
• Added an errno to report errors by another mean than a simple printf like callback
• Finished ID/IDREF support and checking when validation
• Serious memory leaks fixed (there is now a memory wrapper module)
• Improvement of XPath implementation
• Added an HTML parser front-end
