HISTORY of the LZMA SDK-----------------------
9.38 beta 2015-01-03------------------------- - The BUG in 9.30-9.37 was fixed: IArchiveGetRawProps interface was disabled for 7z archives.- The BUG in 9.26-9.36 was fixed: Some code in CPP\7zip\Archive\7z\ worked correctly only under Windows.
9.36 beta 2014-12-26------------------------- - The BUG in command line version was fixed: 7-Zip created temporary archive in current folder during update archive operation, if -w{Path} switch was not specified. The fixed 7-Zip creates temporary archive in folder that contains updated archive.- The BUG in 9.33-9.35 was fixed: 7-Zip silently ignored file reading errors during 7z or gz archive creation, and the created archive contained only part of file that was read before error. The fixed 7-Zip stops archive creation and it reports about error.
9.35 beta 2014-12-07------------------------- - 7zr.exe now support AES encryption.- SFX mudules were added to LZMA SDK- Some bugs were fixed.
9.21 beta 2011-04-11------------------------- - New class FString for file names at file systems.- Speed optimization in CRC code for big-endian CPUs.- The BUG in Lzma2Dec.c was fixed: Lzma2Decode function didn't work.
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
4.61 beta 2008-11-23-------------------------- The bug in ANSI-C LZMA Decoder was fixed: If encoded stream was corrupted, decoder could access memory outside of allocated range.- Some changes in ANSI-C 7z Decoder interfaces.- LZMA SDK is placed in the public domain.
4.60 beta 2008-08-19-------------------------- Some minor fixes.
4.59 beta 2008-08-13-------------------------- The bug was fixed: LZMA Encoder in fast compression mode could access memory outside of allocated range in some rare cases.
4.58 beta 2008-05-05-------------------------- ANSI-C LZMA Decoder was rewritten for speed optimizations.- ANSI-C LZMA Encoder was included to LZMA SDK.- C++ LZMA code now is just wrapper over ANSI-C code.
4.57 2007-12-12-------------------------- Speed optimizations in �++ 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-------------------------- 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-------------------------- 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-------------------------- 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:
2001-08-30: LZMA compression was added to 7-Zip 1999-01-02: First version of 7-Zip was released
