* Mon May 24 2021
  - Update to 2.4.0: [CVE-2013-0340 "Billion Laughs"]
    * Security fixes:
    - 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:
      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
      .. 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:
    - For (non-default) compilation with -DEXPAT_MIN_SIZE=ON (CMake)
      or CPPFLAGS=-DXML_MIN_SIZE (GNU Autotools): Fix segfault
      for UTF-16 payloads containing CDATA sections.
    - Autotools: Fix generated CMake files for non-64bit and
      non-Linux platforms (e.g. macOS and MinGW in particular)
      that were introduced with release 2.3.0
    * Other changes:
    - xmlwf: Improve help output and the xmlwf man page
    - xmlwf: Improve maintainability through some refactoring

      new symbols and error codes; see for
      what these numbers do
* Tue Apr 13 2021
  - Do not BuildRequire cmake: expat is part of the distro bootstrap
    cycle and any additional dependency makes the ring larger. In
    this case here, cmake was even only used to own a directory.
* Tue Apr 06 2021
  - update to 2.3.0:
    * 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).
    * xmlwf: Exit status 2 was used for both:
    - malformed input files (documented) and
    - invalid command-line arguments (undocumented).
      case of invalid command-line arguments now
      has its own exit status 4, resolving the ambiguity.
    * Other changes
* Sun Oct 04 2020
  - Update to 2.2.10:

    - Autotools: Use -Werror while configure tests the compiler for
      supported compile flags to avoid false positives

      ensure that they have the last word over flags added while
      running ./configure

      on suffix "w") with -DEXPAT_CHAR_TYPE=(ushort|wchar_t)

    - CMake: Install pre-compiled shipped xmlwf.1 manpage in case

    - CMake: Introduce option EXPAT_BUILD_PKGCONFIG to control
      generation of pkg-config file "expat.pc"

* Fri Nov 29 2019
  - Version update to 2.2.9
    * Other changes:
    - examples: Drop executable bits from elements.c
      [#349]  Windows: Change the name of the Windows DLLs from expat*.dll
      to libexpat*.dll once more (regression from 2.2.8, first
      fixed in 1.95.3, issue #61 on SourceForge today,
      was issue #432456 back then); needs a fix due
      case-insensitive file systems on Windows and the fact that
      Perl's XML::Parser::Expat compiles into Expat.dll.
      [#347]  Windows: Only define _CRT_RAND_S if not defined
      Version info bumped from 7:10:6 to 7:11:6

      when called from inside of an end element handler
    - xmlwf: Fix exit code for operation without "-d DIRECTORY";

    * Other changes:
    - examples: Improve elements.c

    - ( #539  Fix regression from fix to CVE-2016-0718 cutting off
      longer tag names;
      [#25]  More integer overflow detection (function poolGrow);
    - [MOX-002]      Detect overflow from len=INT_MAX call to XML_Parse;
    - [MOX-005] #30  Use high quality entropy for hash initialization:
    * arc4random_buf on BSD, systems with libbsd
      (when configured with --with-libbsd), CloudABI
    * RtlGenRandom on Windows XP / Server 2003 and later
    * getrandom on Linux 3.17+
      In a way, that's still part of CVE-2016-5300.
    - [MOX-005] For the low quality entropy extraction fallback code,
      the parser instance address can no longer leak,
    - [MOX-003] Prevent use of uninitialised variable; commit
    - [MOX-004] a4dc944f37b664a3ca7199c624a98ee37babdb4b
      Add missing parameter validation to public API functions
      and dedicated error code XML_ERROR_INVALID_ARGUMENT:
    - [MOX-006] * NULL checks; commits
    * Negative length (XML_Parse); commit
    - [MOX-002] 70db8d2538a10f4c022655d6895e4c3e78692e7f
    - [MOX-001] #35  Change hash algorithm to William Ahern's version of SipHash
      to go further with fixing CVE-2012-0876.
    - Bug fixes:
      [#32] Fix sharing of hash salt across parsers;
      relevant where XML_ExternalEntityParserCreate is called
      prior to XML_Parse, in particular (e.g. FBReader)
      [#28] xmlwf: Auto-disable use of memory-mapping (and parsing
      as a single chunk) for files larger than ~1 GB (2^30 bytes)
      rather than failing with error "out of memory"
      [#3]  Fix double free after malloc failure in DTD code; commit
      [#17] Fix memory leak on parser error for unbound XML attribute
      prefix with new namespaces defined in the same tag;
      found by Google's OSS-Fuzz; commits
      xmlwf on Windows: Add missing calls to CloseHandle
    - New features:
      [#30] Introduced environment switch EXPAT_ENTROPY_DEBUG=1
      for runtime debugging of entropy extraction
