           (ZSTD_dfast) by @cyan4973 (#1681)

         * build: CMake: support building with LZ4 @leeyoung624 (#1626)
         * build: CMake: install zstdless and zstdgrep by @leeyoung624 (#1647)
         * build: CMake: respect existing uninstall target by @j301scott (#1619)
         * build: Make: skip multithread tests when built without support by
           @michaelforney (#1620)
         * build: Make: Fix examples/ test target by @sjnam (#1603)
         * build: Meson: rename options out of deprecated namespace by @lzutao

         * build: Fix MinGW-W64 build by @myzhang1029 (#1600)
         * misc: Expand decodecorpus coverage by @ephiepark (#1664)
       - Add baselibs.conf: libarchive gained zstd support and provides
         -32bit libraries. This means, zstd also needs to provide -32bit libs.
       - Update to new upstream release 1.4.0
         * perf: level 1 compression speed was improved
         * cli: added --[no-]compress-literals flag to enable or disable literal
       - Reword "real-time" in description by some actual statistics, because
         603MB/s (lowest zstd level) is not "real-time" for quite some
       - zstd 1.3.8:
         * better decompression speed on large files (+7%) and cold dictionaries
         * slightly better compression ratio at high compression modes
         * new --rsyncable mode
         * support decompression of empty frames into NULL (used to be an error)
         * support ZSTD_CLEVEL environment variable
         * --no-progress flag, preserving final summary
         * various CLI fixes
         * fix race condition in one-pass compression functions that could allow
           out of bounds write (CVE-2019-11922, boo#1142941)
       - zstd 1.3.7:
         * fix ratio for dictionary compression at levels 9 and 10
         * add man pages for zstdless and zstdgrep
       - includes changes from zstd 1.3.6:
         * faster dictionary builder, also the new default for --train
         * previous (slower, slightly higher quality) dictionary builder to be
           selected via --train-cover
         * Faster dictionary decompression and compression under memory limits
           with many dictionaries used simultaneously
         * New command --adapt for compressed network piping of data adjusted to
           the perceived network conditions
       - update to 1.3.5:
         * much faster dictionary compression
         * small quality improvement for dictionary generation
         * slightly improved performance at high compression levels
         * automatic memory release for long duration contexts
         * fix overlapLog can be manually set
         * fix decoding invalid lz4 frames
         * fix performance degradation for dictionary compression when using
           advanced API
       - fix pzstd tests
       - enable pzstd (parallel zstd)
       - Use %license instead of %doc [boo#1082318]
       - Add disk _constraints to fix ppc64le build
       - Use FAT LTO objects in order to provide proper static library
