Release 2.0.1 Tue June 5 2007
        - Fixed bugs #1515266, #1515600: The character data handler's calling
          of XML_StopParser() was not handled properly; if the parser was
          stopped and the handler set to NULL, the parser would segfault.
        - Fixed bug #1690883: Expat failed on EBCDIC systems as it assumed
          some character constants to be ASCII encoded.
        - Minor cleanups of the test harness.
        - Fixed xmlwf bug #1513566: "out of memory" error on file size zero.

          HP-UX, Tru64, Solaris 9: patch #1437840, bug #1196180.
          All Unix: #1554618 (refreshed config.sub/config.guess).
                    #1490371, #1613457: support both, DESTDIR and INSTALL_ROOT,
                    without relying on GNU-Make specific features.
          #1647805: Patched configure.in to work better with Intel compiler.
        - Fixes to Makefile.in to have make check work correctly:

Release 2.0.0 Wed Jan 11 2006
        - We no longer use the "check" library for C unit testing; we
          always use the (partial) internal implementation of the API.
        - Report XML_NS setting via XML_GetFeatureList().
        - Fixed headers for use from C++.
        - XML_GetCurrentLineNumber() and  XML_GetCurrentColumnNumber()
          now return unsigned integers.
        - Added XML_LARGE_SIZE switch to enable 64-bit integers for
          byte indexes and line/column numbers.
        - Updated to use libtool 1.5.22 (the most recent).

Release 1.95.8 Fri Jul 23 2004
        - Major new feature: suspend/resume.  Handlers can now request
          that a parse be suspended for later resumption or aborted
          altogether.  See "Temporarily Stopping Parsing" in the
          documentation for more details.
        - Some mostly minor bug fixes, but compilation should no
          longer generate warnings on most platforms.  SF issues
          include: #827319, #840173, #846309, #888329, #896188, #923913,
          #928113, #961698, #985192.

Release 1.95.7 Mon Oct 20 2003
        - Fixed enum XML_Status issue (reported on SourceForge many
          times), so compilers that are properly picky will be happy.
        - Introduced an XMLCALL macro to control the calling
          convention used by the Expat API; this macro should be used
          to annotate prototypes and definitions of callback
          implementations in code compiled with a calling convention
          other than the default convention for the host platform.
        - Improved ability to build without the configure-generated
          expat_config.h header.  This is useful for applications
          which embed Expat rather than linking in the library.
        - Fixed a variety of bugs: see SF issues #458907, #609603,
          #676844, #679754, #692878, #692964, #695401, #699323, #699487,
          #820946.
        - Improved hash table lookups.
        - Added more regression tests and improved documentation.

Release 1.95.6 Tue Jan 28 2003
        - Added XML_FreeContentModel().
        - Added XML_MemMalloc(), XML_MemRealloc(), XML_MemFree().
        - Fixed a variety of bugs: see SF issues #615606, #616863,
          #618199, #653180, #673791.
        - Enhanced the regression test suite.
        - Man page improvements: includes SF issue #632146.

Release 1.95.5 Fri Sep 6 2002
        - Added XML_UseForeignDTD() for improved SAX2 support.
        - Added XML_GetFeatureList().
        - Defined XML_Bool type and the values XML_TRUE and XML_FALSE.
        - Use an incomplete struct instead of a void* for the parser
          (may not retain).
        - Fixed UTF-8 decoding bug that caused legal UTF-8 to be rejected.
        - Finally fixed bug where default handler would report DTD
          events that were already handled by another handler.
          Initial patch contributed by Darryl Miles.
        - Removed unnecessary DllMain() function that caused static
          linking into a DLL to be difficult.
        - Added VC++ projects for building static libraries.
        - Reduced line-length for all source code and headers to be
          no longer than 80 characters, to help with AS/400 support.
        - Reduced memory copying during parsing (SF patch #600964).
        - Fixed a variety of bugs: see SF issues #580793, #434664,
          #483514, #580503, #581069, #584041, #584183, #584832, #585537,
          #596555, #596678, #598352, #598944, #599715, #600479, #600971.

Release 1.95.4 Fri Jul 12 2002
        - Added support for VMS, contributed by Craig Berry.  See
          vms/README.vms for more information.
        - Added Mac OS (classic) support, with a makefile for MPW,
          contributed by Thomas Wegner and Daryle Walker.
        - Added Borland C++ Builder 5 / BCC 5.5 support, contributed
          by Patrick McConnell (SF patch #538032).
        - Fixed a variety of bugs: see SF issues #441449, #563184,
          #564342, #566334, #566901, #569461, #570263, #575168, #579196.
        - Made skippedEntityHandler conform to SAX2 (see source comment)
        - Re-implemented WFC: Entity Declared from XML 1.0 spec and
          added a new error "entity declared in parameter entity":
          see SF bug report #569461 and SF patch #578161
        - Re-implemented section 5.1 from XML 1.0 spec:
          see SF bug report #570263 and SF patch #578161

Release 1.95.3 Mon Jun 3 2002
        - Added a project to the MSVC workspace to create a wchar_t
          version of the library; the DLLs are named libexpatw.dll.
        - Changed the name of the Windows DLLs from expat.dll to
          libexpat.dll; this fixes SF bug #432456.
        - Added the XML_ParserReset() API function.
        - Fixed XML_SetReturnNSTriplet() to work for element names.
        - Made the XML_UNICODE builds usable (thanks, Karl!).
        - Allow xmlwf to read from standard input.

          #547350.  Other bugs which we can't test as easily may also
          have been fixed, especially in the area of build support.

Release 1.95.2 Fri Jul 27 2001
        - More changes to make MSVC happy with the build; add a single
          workspace to support both the library and xmlwf application.
        - Added a Windows installer for Windows users; includes
          xmlwf.exe.
        - Added compile-time constants that can be used to determine the
          Expat version

          among the various Unix flavors.
        - Fix the UTF-8 BOM bug.
        - Cleaned up warning messages for several compilers.
        - Added the -Wall, -Wstrict-prototypes options for GCC.

Release 1.95.1 Sun Oct 22 15:11:36 EDT 2000
        - Changes to get expat to build under Microsoft compiler
        - Removed all aborts and instead return an UNEXPECTED_STATE error.
        - Fixed a bug where a stray '%' in an entity value would cause an
          abort.
        - Defined XML_SetEndNamespaceDeclHandler. Thanks to Darryl Miles for
          finding this oversight.

        - The reference had the wrong label for XML_SetStartNamespaceDecl.
          Reported by an anonymous user.

Release 1.95.0 Fri Sep 29 2000
        - XML_ParserCreate_MM
                Allows you to set a memory management suite to replace the
                standard malloc,realloc, and free.
        - XML_SetReturnNSTriplet
                If you turn this feature on when namespace processing is in
                effect, then qualified, prefixed element and attribute names
                are returned as "uri|name|prefix" where '|' is whatever
                separator character is used in namespace processing.
        - Merged in features from perl-expat
                o XML_SetElementDeclHandler
                o XML_SetAttlistDeclHandler
                o XML_SetXmlDeclHandler
                o XML_SetEntityDeclHandler
                o StartDoctypeDeclHandler takes 3 additional parameters:
                        sysid, pubid, has_internal_subset
                o Many paired handler setters (like XML_SetElementHandler)
                  now have corresponding individual handler setters
                o XML_GetInputContext for getting the input context of
                  the current parse position.
        - Added reference material
        - Packaged into a distribution that builds a sharable library
