Wed Apr 17 11:30:30 UTC 2019 - Jan Engelhardt <jengelh@inai.de>
- Update to new upstream release 1.4.0
* perf: level 1 compression speed was improved by ~6–8%
* cli: added --[no-]compress-literals flag to enable or disable
literal compression
- Reword "real-time" in description by some actual statistics,
because 603MB/s (lowest zstd level) is not "real-time" for
quite some applications.

Decompression speed is preserved and remains roughly the same at all

Zstd can also offer stronger compression ratios at the cost of At roughly the same ratio, zstd (v1.3.5) achieves ~600%% faster
