This update for zstd to version 1.4.2 fixes the following issues :
Security issues fixed :

Non-security issues fixed :
- Added --[no-]compress-literals CLI flag to enable or disable literal compression.
Added new --rsyncable mode.
Added handling of -f flag to zstdgrep.
Added CPU load indicator for each file on -vv mode.
Changed --no-progress flag to preserve the final summary.
Added new command --adapt for compressed network piping of data adjusted to the perceived network conditions.
