This is part of the fix for bug #3496608 to randomize hash parameters. When compiled with XML_ATTR_INFO defined, adds new API member 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.

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 - 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. - 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. - Defined XML_SetEndNamespaceDeclHandler. Thanks to Darryl Miles for 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
