LZMA Specification (Draft) |
- Note: If you use XZ code from LZMA SDK, it's recommended to upgrade to new
-XZ code from 7-Zip 9.38 beta. That new code fixes some bugs.
-
What's new:
- - 9.38: Some bugs were fixed.
- - 9.36: Some bugs were fixed.
- - 9.35: Some bugs were fixed. AES code and SFXs modules were included to SDK.
+ - 19.00: Encryption strength for 7z archives was increased.
+ - 18.06: Some speed optimiztions in LZMA/LZMA2 code.
+ - 18.05: Some speed optimiztions in LZMA/LZMA2 code.
+ - 18.01: Some changes in LZMA2/xz multithreading code for compressing. Some bugs were fixed.
+ - 9.35: AES code and SFXs modules were included to SDK.
- 9.20: New small SFX module for installers.
- 9.11: PPMd support.
- 9.04: LZMA2 and XZ support.
- - 4.62: Some fixes. LZMA SDK is placed in the public domain.
- - 4.58: Speed optimizations. New ANSI-C code for LZMA compression.
- - 4.57: Speed optimizations. Some fixes.
- - 4.49: .7z ANSI-C decoder was improved. C++ code for .7z archive handling was
- included.
+ - 4.62: LZMA SDK is placed in the public domain.
-LZMA is the default and general compression method of 7z format

LZMA / LZMA2 are default and general compression methods of 7z format
in the 7-Zip program. LZMA provides a high compression ratio and
-very fast decompression, so it is very suitable for embedded applications.
