-HISTORY of the LZMA SDK\r
------------------------\r
-\r
-18.05 2018-04-30\r
--------------------------\r
-- The speed for LZMA/LZMA2 compressing was increased \r
- by 8% for fastest/fast compression levels and \r
- by 3% for normal/maximum compression levels.\r
-- Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in\r
- Windows 10 because of some BUG with "Large Pages" in Windows 10. \r
- Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).\r
-- The BUG was fixed in Lzma2Enc.c\r

- if (inStream == NULL) and the number of block threads is more than 1.\r
-\r
-\r
-18.03 beta 2018-03-04\r
--------------------------\r
-- Asm\x86\LzmaDecOpt.asm: new optimized LZMA decoder written in asm \r
- for x64 with about 30% higher speed than main version of LZMA decoder written in C.\r
-- The speed for single-thread LZMA/LZMA2 decoder written in C was increased by 3%.\r
-- 7-Zip now can use multi-threading for 7z/LZMA2 decoding,\r
- if there are multiple independent data chunks in LZMA2 stream.\r
-- 7-Zip now can use multi-threading for xz decoding,\r
- if there are multiple blocks in xz stream.\r
-\r
-\r

- for compressing from memory to memory. \r
- That BUG is not related to LZMA encoder version that works via streams.\r
