ISA-L fast deflate now has more levels to + balance speed vs. target compression level. Level 0, 1 are as in previous + generations. New levels 2 & 3 target higher compression roughly comparable + to zlib levels 2-3. Level 3 is currently only optimized for processors with + AVX512 instructions. + +* New T10dif & copy function - crc16_t10dif_copy() + - CRC and copy was added to emulate T10dif operations such as DIF insert and + strip.
