    Question Give me newest Win64 lz4.exe & lz5.exe binaries

    1. I want to compare new versions of lz4 & lz5 in fast compression mode on 1 core with my code. Where I can download the binaries for Win64?

    2. Author of lz5 still uses these 3 codewords?

    LZ5 uses 3 types of codewords from 2 to 4 bytes long:
    - 1_OO_LL_MMM OOOOOOOO - 10-bit offset, 3-bit match length, 2-bit literal length
    - 00_LLL_MMM OOOOOOOO OOOOOOOO - 16-bit offset, 3-bit match length, 3-bit literal length
    - 01_LLL_MMM OOOOOOOO OOOOOOOO OOOOOOOO - 24-bit offset, 3-bit match length, 3-bit literal length

    I do not really like them...

    3. As I understand, lz4 uses hash table of 16K*4 bytes, and lz5 uses 1M*4 bytes? My new code compresses data on ~14% better than lz5, but the code need to be rewritten in asm to work faster...

    P.S. At this time I have lz5.exe "Aug 16 2016 Y.Collet & P.Skibinski v1.5.0" for Win64 430851 bytes & lz4.exe v.1.40 for Win32 118272 bytes.

    Sorry, I'm not a native English speaker, I learned German. Yes I've forgotten add thanks, pardons, and danke schöns. We Germans are harsh people.
