 The cmake based buildsystem for expat works on Windows (cygwin, mingw, Visual
 Studio) and should work on all other platform cmake supports.
 
-Assuming ~/expat-2.2.9 is the source directory of expat, add a subdirectory
+Assuming ~/expat-2.4.1 is the source directory of expat, add a subdirectory
 build and change into that directory:
-~/expat-2.2.9$ mkdir build && cd build
-~/expat-2.2.9/build$
+~/expat-2.4.1$ mkdir build && cd build
+~/expat-2.4.1/build$
 
 From that directory, call cmake first, then call make, make test and
 make install in the usual way:
-~/expat-2.2.9/build$ cmake ..
+~/expat-2.4.1/build$ cmake ..
 -- The C compiler identification is GNU
 -- The CXX compiler identification is GNU
 ....
 -- Configuring done
 -- Generating done
--- Build files have been written to: /home/patrick/expat-2.2.9/build
+-- Build files have been written to: /home/patrick/expat-2.4.1/build
 
 If you want to specify the install location for your files, append
 -DCMAKE_INSTALL_PREFIX=/your/install/path to the cmake call.
 
-~/expat-2.2.9/build$ make && make test && make install
+~/expat-2.4.1/build$ make && make test && make install

-Release 2.2.9 Wed Septemper 25 2019
+Release 2.4.1 Sun May 23 2021
+        Bug fixes:
+       #488 #490  Autotools: Fix installed header expat_config.h for multilib
+                    systems; regression introduced in 2.4.0 by pull request #486
+
+        Other changes:
+       #491 #492  Version info bumped from 9:0:8 to 9:1:8;

+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.

+Release 2.3.0 Thu March 25 2021

+            #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

+            #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

+       #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,

+                    while running ./configure

+## Using libexpat in your CMake-Based Project
+
+There are two ways of using libexpat with CMake:
+
+### a) Module Mode
+
+This approach leverages CMake's own [module `FindEXPAT`](https://cmake.org/cmake/help/latest/module/FindEXPAT.html).
+
+Notice the *uppercase* `EXPAT` in the following example:
+
+```cmake
+cmake_minimum_required(VERSION 3.0)  # or 3.10, see below
+
+project(hello VERSION 1.0.0)
+
+find_package(EXPAT 2.2.8 MODULE REQUIRED)
+
+add_executable(hello
+    hello.c
+)
+
+# a) for CMake >=3.10 (see CMake's FindEXPAT docs)
+target_link_libraries(hello PUBLIC EXPAT::EXPAT)
+
+# b) for CMake >=3.0
+target_include_directories(hello PRIVATE ${EXPAT_INCLUDE_DIRS})
+target_link_libraries(hello PUBLIC ${EXPAT_LIBRARIES})
+```
+
+### b) Config Mode
+
+This approach requires files from…
+
+- libexpat >=2.2.8 where packaging uses the CMake build system
+or
+- libexpat >=2.3.0 where packaging uses the GNU Autotools build system
+  on Linux
+or
+- libexpat >=2.4.0 where packaging uses the GNU Autotools build system
+  on macOS or MinGW.
+
+Notice the *lowercase* `expat` in the following example:
+
+```cmake
+cmake_minimum_required(VERSION 3.0)
+
+project(hello VERSION 1.0.0)
+
+find_package(expat 2.2.8 CONFIG REQUIRED char dtd ns)
+
+add_executable(hello
+    hello.c
+)
+
+target_link_libraries(hello PUBLIC expat::expat)
+```

+# EXPAT TEST SCRIPT FOR W3C XML TEST SUITE
+#
 # This script can be used to exercise Expat against the
 # w3c.org xml test suite, available from
 # http://www.w3.org/XML/Test/xmlts20020606.zip.
-
+#
 # To run this script, first set XMLWF below so that xmlwf can be
 # found, then set the output directory with OUTPUT.
-
+#
 # The script lists all test cases where Expat shows a discrepancy
 # from the expected result. Test cases where only the canonical
 # output differs are prefixed with "Output differs:", and a diff file
 # is generated in the appropriate subdirectory under $OUTPUT.
-
+#
 # If there are output files provided, the script will use
 # output from xmlwf and compare the desired output against it.
 # However, one has to take into account that the canonical output
 # produced by xmlwf conforms to an older definition of canonical XML
 # and does not generate notation declarations.
