+ - now it supports BCJ and BCJ2 filters
+ - now it supports files larger than 4 GB.
+ - now it supports "Last Write Time" field for files.
+- C++ code for .7z archives compressing/decompressing from 7-zip
+ was included to LZMA SDK.
+
+
+4.43 2006-06-04
+-------------------------
+- Small changes for more compatibility with some C/C++ compilers.
+
+
+4.42 2006-05-15
+-------------------------

+
+
+4.39 beta 2006-04-14
+-------------------------
+- The bug in versions 4.33b:4.38b was fixed:
+ C++ version of LZMA encoder could not correctly compress
+ files larger than 2 GB with HC4 match finder (-mfhc4).
+
+
+4.37 beta 2005-04-06
+-------------------------
+- Fixes in C++ code: code could no be compiled if _NO_EXCEPTIONS was defined.
+
+
+4.35 beta 2005-03-02
+-------------------------
+- The bug was fixed in C++ version of LZMA Decoder:
+ If encoded stream was corrupted, decoder could access memory
+ outside of allocated range.
+
+
+4.34 beta 2006-02-27
+-------------------------
+- Compressing speed and memory requirements for compressing were increased
+- LZMA now can use only these match finders: HC4, BT2, BT3, BT4
+
+
+4.32 2005-12-09
+-------------------------
+- Java version of LZMA SDK was included
+
+
+4.30 2005-11-20
+-------------------------
+- Compression ratio was improved in -a2 mode
+- Speed optimizations for compressing in -a2 mode
+- -fb switch now supports values up to 273
+- The bug in 7z_C (7zIn.c) was fixed:
+ It used Alloc/Free functions from different memory pools.
+ So if program used two memory pools, it worked incorrectly.
+- 7z_C: .7z format supporting was improved
+- LZMA# SDK (C#.NET version) was included
+
+
+4.27 (Updated) 2005-09-21
+-------------------------
+- Some GUIDs/interfaces in C++ were changed.
+ IStream.h:
+ ISequentialInStream::Read now works as old ReadPart
+ ISequentialOutStream::Write now works as old WritePart
+
+
+4.27 2005-08-07
+-------------------------
+- The bug in LzmaDecodeSize.c was fixed:
+ if _LZMA_IN_CB and _LZMA_OUT_READ were defined,
+ decompressing worked incorrectly.
+
+
+4.26 2005-08-05
+-------------------------
+- Fixes in 7z_C code and LzmaTest.c:
+ previous versions could work incorrectly,
+ if malloc(0) returns 0
+
+
+4.23 2005-06-29

+
+
+4.22 2005-06-10

+
+
+4.17 2005-04-18
+-------------------------
+- New example for RAM->RAM compressing/decompressing:
+ LZMA + BCJ (filter for x86 code):
+ - LzmaRam.h
+ - LzmaRam.cpp
+ - LzmaRamDecode.h
+ - LzmaRamDecode.c
+ - -f86 switch for lzma.exe
+
+
+4.16 2005-03-29
+-------------------------
+- The bug was fixed in LzmaDecode.c (ANSI-C LZMA Decoder):
+ If _LZMA_OUT_READ was defined, and if encoded stream was corrupted,
+ decoder could access memory outside of allocated range.
+- Speed optimization of ANSI-C LZMA Decoder (now it's about 20% faster).
+ Old version of LZMA Decoder now is in file LzmaDecodeSize.c.
+ LzmaDecodeSize.c can provide slightly smaller code than LzmaDecode.c
+- Small speed optimization in LZMA C++ code
+- filter for SPARC's code was added
+- Simplified version of .7z ANSI-C Decoder was included
+
+
+4.06 2004-09-05
+-------------------------
+- The bug in v4.05 was fixed:
+ LZMA-Encoder didn't release output stream in some cases.
+
+
+4.05 2004-08-25
+-------------------------
+- Source code of filters for x86, IA-64, ARM, ARM-Thumb
+ and PowerPC code was included to SDK
+- Some internal minor changes
+
+
+4.04 2004-07-28
+-------------------------
+- More compatibility with some C++ compilers
+
+
+4.03 2004-06-18
+-------------------------
+- "Benchmark" command was added. It measures compressing
+ and decompressing speed and shows rating values.
+ Also it checks hardware errors.
+
+
+4.02 2004-06-10
+-------------------------
+- C++ LZMA Encoder/Decoder code now is more portable
+ and it can be compiled by GCC on Linux.
+
+
+4.01 2004-02-15
+-------------------------
+- Some detection of data corruption was enabled.
+ LzmaDecode.c / RangeDecoderReadByte
+ .....
+ {
+ rd->ExtraBytes = 1;
+ return 0xFF;
+ }
+
+
+4.00 2004-02-13
+-------------------------
+- Original version of LZMA SDK
+
+
+
+HISTORY of the LZMA
+-------------------
+ 2001-2008: Improvements to LZMA compressing/decompressing code,
+ keeping compatibility with original LZMA format
+ 1996-2001: Development of LZMA compression format
+
+ Some milestones:
