HISTORY of the LZMA SDK
-----------------------
+9.18 beta 2010-11-02
+-------------------------
+- New small SFX module for installers (SfxSetup).
+
+
+9.12 beta 2010-03-24
+-------------------------
+- The BUG in LZMA SDK 9.* was fixed: LZMA2 codec didn't work,
+ if more than 10 threads were used (or more than 20 threads in some modes).
+
+
+9.11 beta 2010-03-15
+-------------------------
+- 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.
+
+
+9.04 2009-05-30
+-------------------------
+- LZMA2 compression method support
+- xz format support
+
+
4.65 2009-02-03
-------------------------
- Some minor fixes
