    Hello

    A new zstd version is out a few days ago :)

    Zstd v1.4.5 Release Notes

    This is a fairly important release which includes performance improvements and new major CLI features. It also fixes a few corner cases, making it a recommended upgrade.

    Faster Decompression Speed
    Decompression speed has been improved again, thanks to great contributions from @terrelln.
    As usual, exact mileage varies depending on files and compilers.
    For x64 cpus, expect a speed bump of at least +5%, and up to +10% in favorable cases.
    ARM cpus receive more benefit, with speed improvements ranging from +15% vicinity, and up to +50% for certain SoCs and scenarios (ARM‘s situation is more complex due to larger differences in SoC designs).

    For illustration, some benchmarks run on a modern x64 platform using zstd -b compiled with gcc v9.3.0 :
