+Release 2.4.4 Sun January 30 2022
+        Security fixes:
+            #550  CVE-2022-23852 -- Fix signed integer overflow
+                    (undefined behavior) in function XML_GetBuffer
+                    (that is also called by function XML_Parse internally)
+                    for when XML_CONTEXT_BYTES is defined to >0 (which is both
+                    common and default).
+                    Impact is denial of service or more.
+            #551  CVE-2022-23990 -- Fix unsigned integer overflow in function
+                    doProlog triggered by large content in element type
+                    declarations when there is an element declaration handler
+                    present (from a prior call to XML_SetElementDeclHandler).
+                    Impact is denial of service or more.
+
+        Bug fixes:
+       #544 #545  xmlwf: Fix a memory leak on output file opening error

+Release 2.4.3 Sun January 16 2022
+        Security fixes:
+       #531 #534  CVE-2021-45960 -- Fix issues with left shifts by >=29 places
+                    resulting in
+                      a) realloc acting as free
+                      b) realloc allocating too few bytes
+                      c) undefined behavior
+                    depending on architecture and precise value
+                    for XML documents with >=2^27+1 prefixed attributes
+                    on a single XML tag a la
+                    "<r xmlns:a='[..]' a:a123='[..]' [..] />"
+                    where XML_ParserCreateNS is used to create the parser
+                    (which needs argument "-n" when running xmlwf).
+                    Impact is denial of service, or more.
+       #532 #538  CVE-2021-46143 (ZDI-CAN-16157) -- Fix integer overflow
+                    on variable m_groupSize in function doProlog leading
+                    to realloc acting as free.

+Release 2.4.0 Sun May 23 2021
+        Security fixes:
+   #34 #466 #484  CVE-2013-0340/CWE-776 -- Protect against billion laughs attacks
+                    (denial-of-service; flavors targeting CPU time or RAM or both,
+                    leveraging general entities or parameter entities or both)
+                    by tracking and limiting the input amplification factor
+                    (<amplification> := (<direct> + <indirect>) / <direct>).
+                    By conservative default, amplification up to a factor of 100.0
+                    is tolerated and rejection only starts after 8 MiB of output bytes
+                    (=<direct> + <indirect>) have been processed.
+                    The fix adds the following to the API:
+                    - A new error code XML_ERROR_AMPLIFICATION_LIMIT_BREACH to
+                      signals this specific condition.
+                    - Two new API functions ..
+                      - XML_SetBillionLaughsAttackProtectionMaximumAmplification and
+                      - XML_SetBillionLaughsAttackProtectionActivationThreshold
+                      .. to further tighten billion laughs protection parameters
+                      when desired.  Please see file "doc/reference.html" for details.
+                      If you ever need to increase the defaults for non-attack XML
+                      payload, please file a bug report with libexpat.
+                    - Two new XML_FEATURE_* constants ..
+                      - that can be queried using the XML_GetFeatureList function, and
+                      - that are shown in "xmlwf -v" output.
+                    - Two new environment variable switches ..
+                      - EXPAT_ACCOUNTING_DEBUG=(0|1|2|3) and
+                      - EXPAT_ENTITY_DEBUG=(0|1)
+                      .. for runtime debugging of accounting and entity processing.
+                      Specific behavior of these values may change in the future.
+                    - Two new command line arguments "-a FACTOR" and "-b BYTES"
+                      for xmlwf to further tighten billion laughs protection
+                      parameters when desired.
+                      If you ever need to increase the defaults for non-attack XML
+                      payload, please file a bug report with libexpat.
+
+        Bug fixes:

+Release 2.3.0 Thu March 25 2021
+        Bug fixes:
+            #438  When calling XML_ParseBuffer without a prior successful call to
+                    XML_GetBuffer as a user, no longer trigger undefined behavior
+                    (by adding an integer to a NULL pointer) but rather return
+                    XML_STATUS_ERROR and set the error code to (new) code
+                    XML_ERROR_NO_BUFFER. Found by UBSan (UndefinedBehaviorSanitizer)
+                    of Clang 11 (but not Clang 9).
+            #444  xmlwf: Exit status 2 was used for both:
+                    - malformed input files (documented) and
+                    - invalid command-line arguments (undocumented).
+                    The case of invalid command-line arguments now
+                    has its own exit status 4, resolving the ambiguity.
+
+        Other changes:

+        - 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
+        - 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
