+
+9.12 beta      2010-03-24
+-------------------------
+- The BUG in LZMA SDK 9.* was fixed: LZMA2 codec didn't work,

+-------------------------
+- PPMd compression method support
+
+
+9.09           2009-12-12
+-------------------------
+- The bug was fixed:
+   Utf16_To_Utf8 funstions in UTFConvert.cpp and 7zMain.c
+   incorrectly converted surrogate characters (the code >= 0x10000) to UTF-8.
+- Some bugs were fixed
+
+
+9.06           2009-08-17
+-------------------------
+- Some changes in ANSI-C 7z Decoder interfaces.
