 The cmake based buildsystem for expat works on Windows (cygwin, mingw, Visual
 Studio) and should work on all other platform cmake supports.
 
-Assuming ~/expat-2.2.10 is the source directory of expat, add a subdirectory
+Assuming ~/expat-2.3.0 is the source directory of expat, add a subdirectory
 build and change into that directory:
-~/expat-2.2.10$ mkdir build && cd build
-~/expat-2.2.10/build$
+~/expat-2.3.0$ mkdir build && cd build
+~/expat-2.3.0/build$
 
 From that directory, call cmake first, then call make, make test and
 make install in the usual way:
-~/expat-2.2.10/build$ cmake ..
+~/expat-2.3.0/build$ cmake ..
 -- The C compiler identification is GNU

 If you want to specify the install location for your files, append
 -DCMAKE_INSTALL_PREFIX=/your/install/path to the cmake call.

+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:
+            #439  xmlwf: Add argument -k to allow continuing after
+                    non-fatal errors
+            #439  xmlwf: Add section about exit status to the -h help output
+  #422 #426 #447  Windows: Drop support for Visual Studio <=14.0/2015
+            #434  Windows: CMake: Detect unsupported Visual Studio at
+                    configure time (rather than at compile time)
+       #382 #428  testrunner: Make verbose mode (argument "-v") report
+                    about passed tests, and make default mode report about
+                    failures, as well.
+            #442  CMake: Call "enable_language(CXX)" prior to tinkering
+                    with CMAKE_CXX_* variables
+            #448  Document use of libexpat from a CMake-based project
+            #451  Autotools: Install CMake files as generated by CMake 3.19.6
+                    so that users with "find_package(expat [..] CONFIG [..])"
+                    are served on distributions that are *not* using the CMake
+                    build system inside for libexpat packaging
+       #436 #437  Autotools: Drop obsolescent macro AC_HEADER_STDC
+       #450 #452  Autotools: Resolve use of obsolete macro AC_CONFIG_HEADER
+            #441  Address compiler warnings
+            #443  Version info bumped from 7:12:6 to 8:0:7
+                    due to addition of error code XML_ERROR_NO_BUFFER
+                    (see https://verbump.de/ for what these numbers do)
