+ #1983953, 2517952, 2517962, 2649838:
+ Build modifications using autoreconf instead of buildconf.sh.

+ XML_GetAttributeInfo() that allows retrieving the byte
+ offsets for attribute names and values (patch #3446384).
+ Added CMake build system.
+ See bug #2990652 and patch #3312568.
+ Added run-benchmark target to Makefile.in - relies on testdata module
+ present in the same relative location as in the repository.
+
+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.
+ - Fixed outline.c bug #1543233: missing a final XML_ParserFree() call.
+ - Fixes and improvements for Windows platform:
+ bugs #1409451, #1476160, #1548182, #1602769, #1717322.
+ - Build fixes for various platforms:
+ 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:
+ bugs #1408143, #1535603, #1536684.
+ - Added Open Watcom support: patch #1523242.
+
+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).
+ - Added support for AmigaOS.
+ - Some mostly minor bug fixes. SF issues include: #1006708,
+ #1021776, #1023646, #1114960, #1156398, #1221160, #1271642.
+
+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

+ 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.
+ - Install a man page for xmlwf on Unix systems.
+ - Fixed many bugs; see SF bug reports #231864, #461380, #464837,
+ #466885, #469226, #477667, #484419, #487840, #494749, #496505,
+ #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
+ - Removed a lot of GNU-specific dependencies to aide portability
+ 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.

+ finding this oversight.
+ - Changed default patterns in lib/Makefile.in to fit non-GNU makes
+ Thanks to robin@unrated.net for reporting and providing an
+ account to test on.
+ - 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
