@ -244,7 +244,7 @@ A. It has been tested on gcc, ekopath and the intel compiler successfully
previously. Whether the commercial compilers help or not, I could not tell you.
Q. What codebase are you basing this on?
A. rzip v2.1 and lzma sdk907, but it should be possible to stay in sync with
A. rzip v2.1 and lzma sdk920, but it should be possible to stay in sync with
each of these in the future.
Q. Do we really need yet another compression format?

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
4.63 2008-12-31
-------------------------
- Some minor fixes
