HISTORY of the LZMA SDK HISTORY of the LZMA SDK
----------------------- -----------------------
19.00 2019-02-21
-------------------------
- Encryption strength for 7z archives was increased:
the size of random initialization vector was increased from 64-bit to 128-bit,
and the pseudo-random number generator was improved.
- The bug in 7zIn.c code was fixed.
18.06 2018-12-30
-------------------------
- The speed for LZMA/LZMA2 compressing was increased by 3-10%,
and there are minor changes in compression ratio.
- Some bugs were fixed.
- The bug in 7-Zip 18.02-18.05 was fixed:
There was memory leak in multithreading xz decoder - XzDecMt_Decode(),
if xz stream contains only one block.
- The changes for MSVS compiler makefiles:
- the makefiles now use "PLATFORM" macroname with values (x64, x86, arm64)
instead of "CPU" macroname with values (AMD64, ARM64).
- the makefiles by default now use static version of the run-time library.
18.05 2018-04-30 18.05 2018-04-30
