- 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 | |

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, | |

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 | |

------------------------- | |
- Source code of filters for x86, IA-64, ARM, ARM-Thumb | |
and PowerPC code was included to SDK | |
- Some internal minor changes | |

------------------------- | |
- 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 | |
