XZ Utils Release Notes
======================
+5.2.4 (2018-04-29)
+
+ * liblzma:
+
+ - Allow 0 as memory usage limit instead of returning
+ LZMA_PROG_ERROR. Now 0 is treated as if 1 byte was specified,
+ which effectively is the same as 0.
+
+ - Use "noexcept" keyword instead of "throw()" in the public
+ headers when a C++11 (or newer standard) compiler is used.
+
+ - Added a portability fix for recent Intel C Compilers.
+
+ - Microsoft Visual Studio build files have been moved under
+ windows/vs2013 and windows/vs2017.
+
+ * xz:
+
+ - Fix "xz --list --robot missing_or_bad_file.xz" which would
+ try to print an unitialized string and thus produce garbage
+ output. Since the exit status is non-zero, most uses of such
+ a command won't try to interpret the garbage output.
+
+ - "xz --list foo.xz" could print "Internal error (bug)" in a
+ corner case where a specific memory usage limit had been set.
+
+
5.2.3 (2016-12-30)
