+- Update to version 18.06
+  * The speed for LZMA/LZMA2 compressing was increased by 3-10%,
+    and there are minor changes in compression ratio.
+  * Some bugs were fixed.
+  * The bug in 7-Zip 18.02-18.05 was fixed:
+    There was memory leak in multithreading xz decoder -
+    XzDecMt_Decode(), if xz stream contains only one block.
+  * The changes for MSVS compiler makefiles:
+    + the makefiles now use "PLATFORM" macroname with values
+      (x64, x86, arm64) instead of "CPU" macroname with values
+      (AMD64, ARM64).
+    + the makefiles by default now use static version of the
+      run-time library.
