+Release 2.2.10 Sat October 3 2020
+ Bug fixes:

+ pointer arithmetic with NULL pointers
+ #404 #405 Fix reading uninitialized variable during parsing
+ #406 xmlwf: Add missing check for malloc NULL return
+
+ Other changes:
+ #396 Windows: Drop support for Visual Studio <=8.0/2005
+ #409 Windows: Add missing file "Changes" to the installer
+ to fix compilation with CMake from installed sources
+ #403 xmlwf: Document exit codes in xmlwf manpage and

+ when used with "-d DIRECTORY"
+ #356 #359 MinGW: Provide declaration of rand_s for mingwrt <5.3.0
+ #383 #392 Autotools: Use -Werror while configure tests the compiler
+ for supported compile flags to avoid false positives
+ #383 #393 #394 Autotools: Improve handling of user (C|CPP|CXX|LD)FLAGS,
+ e.g. ensure that they have the last word over flags added
+ while running ./configure
+ #360 CMake: Create libexpatw.{dll,so} and expatw.pc (with emphasis
+ on suffix "w") with -DEXPAT_CHAR_TYPE=(ushort|wchar_t)
+ #360 CMake: Detect and deny unsupported build combinations
+ involving -DEXPAT_CHAR_TYPE=(ushort|wchar_t)
+ #360 CMake: Install pre-compiled shipped xmlwf.1 manpage in case
+ of -DEXPAT_BUILD_DOCS=OFF
+ #375 #380 #419 CMake: Fix use of Expat by means of add_subdirectory
+ #407 #408 CMake: Keep expat target name constant at "expat"
+ (i.e. refrain from using the target name to control
+ build artifact filenames)
+ #385 CMake: Fix compilation with -DEXPAT_SHARED_LIBS=OFF for
+ Windows
+ CMake: Expose man page compilation as target "xmlwf-manpage"
+ #413 #414 CMake: Introduce option EXPAT_BUILD_PKGCONFIG
+ to control generation of pkg-config file "expat.pc"
+ #424 CMake: Add minimalistic support for building binary packages
+ with CMake target "package"; based on CPack

+Release 2.2.9 Wed September 25 2019
+ 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

+Release 2.2.8 Fri September 13 2019
+ Security fixes:
+ #317 #318 CVE-2019-15903 -- Fix heap overflow triggered by
+ XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber),
+ and deny internal entities closing the doctype;
+ fixed in commit c20b758c332d9a13afbbb276d30db1d183a85d43
+
+ Bug fixes:
+ #240 Fix cases where XML_StopParser did not have any effect
+ when called from inside of an end element handler
+ #341 xmlwf: Fix exit code for operation without "-d DIRECTORY";
+ previously, only "-d DIRECTORY" would give you a proper
+ exit code:
+ # xmlwf -d . <<<'<not well-formed>' 2>/dev/null ; echo $?
+ 2
+ # xmlwf <<<'<not well-formed>' 2>/dev/null ; echo $?
+ 0
+ Now both cases return exit code 2.
