+HISTORY of the LZMA SDK
+-----------------------
+
+ 4.57 2007-12-12
+ -------------------------
+ - Speed optimizations in Ñ++ LZMA Decoder.
+ - Small changes for more compatibility with some C/C++ compilers.
+
+
+ 4.49 beta 2007-07-05
+ -------------------------
+ - .7z ANSI-C Decoder:
+ - 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
+ -------------------------
+ - Small changes in .h files in ANSI-C version.
+
+
+ 4.39 beta 2006-04-14
+ -------------------------
+ - 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
+ -------------------------
+ - 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
+ - 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
+ -------------------------
+ - 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
+ -------------------------
+ - Small fixes in C++ code
+
+
+ 4.22 2005-06-10
+ -------------------------
+ - Small fixes
+
+
+ 4.21 2005-06-08
+ -------------------------
+ - Interfaces for ANSI-C LZMA Decoder (LzmaDecode.c) were changed
+ - New additional version of ANSI-C LZMA Decoder with zlib-like interface:
+ - LzmaStateDecode.h
+ - LzmaStateDecode.c
+ - LzmaStateTest.c
+ - ANSI-C LZMA Decoder now can decompress files larger than 4 GB
+
+
+ 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
+ -------------------------
+ - 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
+ -------------------------
+ - 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
+-------------------
+ 2001-2007: Improvements to LZMA compressing/decompressing code,
+ keeping compatibility with original LZMA format
+ 1996-2001: Development of LZMA compression format
+
+ Some milestones:
+
+ 2001-08-30: LZMA compression was added to 7-Zip
