- 9.04: LZMA2 and XZ support.
- 4.62: LZMA SDK is placed in the public domain.
LZMA / LZMA2 are default and general compression methods of 7z format in the 7-Zip program. LZMA provides a high compression ratio and fast decompression, so it is very suitable for embedded applications. For example, it can be used for ROM (firmware) compressing.
LZMA SDK includes:
- C++ source code of LZMA Encoder and Decoder
- C++ source code for .7z compression and decompression (reduced version)
- ANSI-C compatible source code for LZMA / LZMA2 / XZ compression and decompression
- ANSI-C compatible source code for 7z decompression with example
- C# source code for LZMA compression and decompression
- Java source code for LZMA compression and decompression
- lzma.exe for .lzma compression and decompression
- 7zr.exe to work with 7z archives (reduced version of 7z.exe from 7-Zip)
- SFX modules to create self-extracting packages and installers
ANSI-C and C++ source code in LZMA SDK is subset of source code of 7-Zip.
