What's new:
+ - 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.
