5Release 2.2.8 Fri Septemper 13 2019
6        Security fixes:
7       #317 #318  CVE-2019-15903 -- Fix heap overflow triggered by
8                    XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber),
9                    and deny internal entities closing the doctype;
10                    fixed in commit c20b758c332d9a13afbbb276d30db1d183a85d43

12        Bug fixes:
13            #240  Fix cases where XML_StopParser did not have any effect
14                    when called from inside of an end element handler
15            #341  xmlwf: Fix exit code for operation without "-d DIRECTORY";
16                    previously, only "-d DIRECTORY" would give you a proper
17                    exit code:
18                      # xmlwf -d . <<<'<not well-formed>' 2>/dev/null ; echo $?
19                      2
20                      # xmlwf <<<'<not well-formed>' 2>/dev/null ; echo $?
21                      0
22                    Now both cases return exit code 2.

545          #1785430: Expat build fails on linux-amd64 with gcc version>=4.1 -O3.
546          #1983953, 2517952, 2517962, 2649838:
547                Build modifications using autoreconf instead of buildconf.sh.
548          #2815947, #2884086: OBJEXT and EXEEXT support while building.
549          #2517938: xmlwf should return non-zero exit status if not well-formed.
550          #2517946: Wrong statement about XMLDecl in xmlwf.1 and xmlwf.sgml.
551          #2855609: Dangling positionPtr after error.
552          #2990652: CMake support.
553          #3010819: UNEXPECTED_STATE with a trailing "%" in entity value.
554          #3206497: Uninitialized memory returned from XML_Parse.
555          #3287849: make check fails on mingw-w64.
556        - Patches:
557          #1749198: pkg-config support.
558          #3010222: Fix for bug #3010819.
559          #3312568: CMake support.
560          #3446384: Report byte offsets for attr names and values.
561        - New Features / API changes:
562          Added new API member XML_SetHashSalt() that allows setting an initial
563                value (salt) for hash calculations. This is part of the fix for
564                bug #3496608 to randomize hash parameters.
565          When compiled with XML_ATTR_INFO defined, adds new API member
566                XML_GetAttributeInfo() that allows retrieving the byte
567                offsets for attribute names and values (patch #3446384).
568          Added CMake build system.
569                See bug #2990652 and patch #3312568.
570          Added run-benchmark target to Makefile.in - relies on testdata module
571                present in the same relative location as in the repository.
572
573Release 2.0.1 Tue June 5 2007
574        - Fixed bugs #1515266, #1515600: The character data handler's calling
575          of XML_StopParser() was not handled properly; if the parser was
576          stopped and the handler set to NULL, the parser would segfault.
577        - Fixed bug #1690883: Expat failed on EBCDIC systems as it assumed
578          some character constants to be ASCII encoded.
579        - Minor cleanups of the test harness.
580        - Fixed xmlwf bug #1513566: "out of memory" error on file size zero.
581        - Fixed outline.c bug #1543233: missing a final XML_ParserFree() call.
582        - Fixes and improvements for Windows platform:
583          bugs #1409451, #1476160, #1548182, #1602769, #1717322.
584        - Build fixes for various platforms:
585          HP-UX, Tru64, Solaris 9: patch #1437840, bug #1196180.
586          All Unix: #1554618 (refreshed config.sub/config.guess).
587                    #1490371, #1613457: support both, DESTDIR and INSTALL_ROOT,
588                    without relying on GNU-Make specific features.
589          #1647805: Patched configure.in to work better with Intel compiler.
590        - Fixes to Makefile.in to have make check work correctly:
591          bugs #1408143, #1535603, #1536684.
592        - Added Open Watcom support: patch #1523242.
593
594Release 2.0.0 Wed Jan 11 2006
595        - We no longer use the "check" library for C unit testing; we
596          always use the (partial) internal implementation of the API.
597        - Report XML_NS setting via XML_GetFeatureList().
598        - Fixed headers for use from C++.
599        - XML_GetCurrentLineNumber() and  XML_GetCurrentColumnNumber()
600          now return unsigned integers.
601        - Added XML_LARGE_SIZE switch to enable 64-bit integers for
602          byte indexes and line/column numbers.
603        - Updated to use libtool 1.5.22 (the most recent).
604        - Added support for AmigaOS.
605        - Some mostly minor bug fixes. SF issues include: #1006708,
606          #1021776, #1023646, #1114960, #1156398, #1221160, #1271642.
607
608Release 1.95.8 Fri Jul 23 2004
609        - Major new feature: suspend/resume.  Handlers can now request
610          that a parse be suspended for later resumption or aborted
611          altogether.  See "Temporarily Stopping Parsing" in the
612          documentation for more details.
613        - Some mostly minor bug fixes, but compilation should no
614          longer generate warnings on most platforms.  SF issues
615          include: #827319, #840173, #846309, #888329, #896188, #923913,
616          #928113, #961698, #985192.
617
618Release 1.95.7 Mon Oct 20 2003
619        - Fixed enum XML_Status issue (reported on SourceForge many
620          times), so compilers that are properly picky will be happy.
621        - Introduced an XMLCALL macro to control the calling
622          convention used by the Expat API; this macro should be used
623          to annotate prototypes and definitions of callback
624          implementations in code compiled with a calling convention
625          other than the default convention for the host platform.
626        - Improved ability to build without the configure-generated
627          expat_config.h header.  This is useful for applications
628          which embed Expat rather than linking in the library.
629        - Fixed a variety of bugs: see SF issues #458907, #609603,
630          #676844, #679754, #692878, #692964, #695401, #699323, #699487,
631          #820946.
632        - Improved hash table lookups.
633        - Added more regression tests and improved documentation.
634
635Release 1.95.6 Tue Jan 28 2003
636        - Added XML_FreeContentModel().
637        - Added XML_MemMalloc(), XML_MemRealloc(), XML_MemFree().
638        - Fixed a variety of bugs: see SF issues #615606, #616863,
639          #618199, #653180, #673791.
640        - Enhanced the regression test suite.
641        - Man page improvements: includes SF issue #632146.
642
643Release 1.95.5 Fri Sep 6 2002
644        - Added XML_UseForeignDTD() for improved SAX2 support.
645        - Added XML_GetFeatureList().
646        - Defined XML_Bool type and the values XML_TRUE and XML_FALSE.
647        - Use an incomplete struct instead of a void* for the parser
648          (may not retain).
649        - Fixed UTF-8 decoding bug that caused legal UTF-8 to be rejected.
650        - Finally fixed bug where default handler would report DTD
651          events that were already handled by another handler.
652          Initial patch contributed by Darryl Miles.
653        - Removed unnecessary DllMain() function that caused static
654          linking into a DLL to be difficult.
655        - Added VC++ projects for building static libraries.
656        - Reduced line-length for all source code and headers to be
657          no longer than 80 characters, to help with AS/400 support.
658        - Reduced memory copying during parsing (SF patch #600964).
659        - Fixed a variety of bugs: see SF issues #580793, #434664,
660          #483514, #580503, #581069, #584041, #584183, #584832, #585537,
661          #596555, #596678, #598352, #598944, #599715, #600479, #600971.
662
663Release 1.95.4 Fri Jul 12 2002
664        - Added support for VMS, contributed by Craig Berry.  See
665          vms/README.vms for more information.
666        - Added Mac OS (classic) support, with a makefile for MPW,
667          contributed by Thomas Wegner and Daryle Walker.
668        - Added Borland C++ Builder 5 / BCC 5.5 support, contributed
669          by Patrick McConnell (SF patch #538032).
670        - Fixed a variety of bugs: see SF issues #441449, #563184,
671          #564342, #566334, #566901, #569461, #570263, #575168, #579196.
672        - Made skippedEntityHandler conform to SAX2 (see source comment)
673        - Re-implemented WFC: Entity Declared from XML 1.0 spec and
674          added a new error "entity declared in parameter entity":
675          see SF bug report #569461 and SF patch #578161
676        - Re-implemented section 5.1 from XML 1.0 spec:
677          see SF bug report #570263 and SF patch #578161
678
679Release 1.95.3 Mon Jun 3 2002
680        - Added a project to the MSVC workspace to create a wchar_t
681          version of the library; the DLLs are named libexpatw.dll.
682        - Changed the name of the Windows DLLs from expat.dll to
683          libexpat.dll; this fixes SF bug #432456.
684        - Added the XML_ParserReset() API function.
685        - Fixed XML_SetReturnNSTriplet() to work for element names.

690          #466885, #469226, #477667, #484419, #487840, #494749, #496505,
691          #547350.  Other bugs which we can't test as easily may also
692          have been fixed, especially in the area of build support.
693
694Release 1.95.2 Fri Jul 27 2001
695        - More changes to make MSVC happy with the build; add a single
696          workspace to support both the library and xmlwf application.
697        - Added a Windows installer for Windows users; includes
698          xmlwf.exe.
699        - Added compile-time constants that can be used to determine the
700          Expat version
701        - Removed a lot of GNU-specific dependencies to aide portability
702          among the various Unix flavors.
703        - Fix the UTF-8 BOM bug.

706
707Release 1.95.1 Sun Oct 22 15:11:36 EDT 2000
708        - Changes to get expat to build under Microsoft compiler
709        - Removed all aborts and instead return an UNEXPECTED_STATE error.
710        - Fixed a bug where a stray '%' in an entity value would cause an
711          abort.
712        - Defined XML_SetEndNamespaceDeclHandler. Thanks to Darryl Miles for
713          finding this oversight.
714        - Changed default patterns in lib/Makefile.in to fit non-GNU makes
715          Thanks to robin@unrated.net for reporting and providing an
716          account to test on.
717        - The reference had the wrong label for XML_SetStartNamespaceDecl.
718          Reported by an anonymous user.
719
720Release 1.95.0 Fri Sep 29 2000
721        - XML_ParserCreate_MM
722                Allows you to set a memory management suite to replace the
723                standard malloc,realloc, and free.
724        - XML_SetReturnNSTriplet
725                If you turn this feature on when namespace processing is in
726                effect, then qualified, prefixed element and attribute names
727                are returned as "uri|name|prefix" where '|' is whatever
728                separator character is used in namespace processing.
729        - Merged in features from perl-expat
730                o XML_SetElementDeclHandler
731                o XML_SetAttlistDeclHandler
732                o XML_SetXmlDeclHandler
733                o XML_SetEntityDeclHandler
734                o StartDoctypeDeclHandler takes 3 additional parameters:
735                        sysid, pubid, has_internal_subset
736                o Many paired handler setters (like XML_SetElementHandler)
737                  now have corresponding individual handler setters
738                o XML_GetInputContext for getting the input context of
739                  the current parse position.
740        - Added reference material
741        - Packaged into a distribution that builds a sharable library
742
