Zstandard v1.4.7
I have been incredibly impressed with Zstandard, and if you are not currently using I suggest giving it a try.I'm a sysadmin so this has worked it's way into every corner of my servers, from backups, to log compression, and more.  Most of my servers run FreeBSD, and with the merge of linux/FreeBSD ZFS I am looking forward to the integration of ZSTD into ZFS so I can use that for on-the-fly Zpool compression.I can safely say that ZSTD has saved me TB of space over LZ4 & GZIP.
