Log message:
zstd: updated to 1.3.7

Zstandard v1.3.7
perf: slightly better decompression speed on clang (depending on hardware target)
fix: ratio for dictionary compression at levels 9 and 10, reported by @indygreg
build: no longer build backtrace by default in release mode; restrict further \ 
automatic mode
build: control backtrace support through build macro BACKTRACE
misc: added man pages for zstdless and zstdgrep, by @samrussell

Log message:
zstd: updated to 1.3.6

Zstandard v1.3.6 release is focused on intensive dictionary compression for \ 
database scenarios.

This is a new environment we are experimenting. The success of dictionary \ 
compression on small data, of which databases tend to store plentiful, led to \ 
increased adoption, and we now see scenarios where literally thousands of \ 
dictionaries are being used simultaneously, with permanent generation or update \ 
of new dictionaries.

Log message:
zstd: updated to 1.3.4

The v1.3.4 release of Zstandard is focused on performance, and offers nice speed \ 
boost in most scenarios.

Log message:
zstd: updated to 1.3.3

1.3.3:
perf: improved zstd_opt strategy (levels 16-19)
fix : bug 944 : multithreading with shared ditionary and large data
cli : fix : content size written in header by default
cli : fix : improved LZ4 format support
cli : new : hidden command -b -S, to benchmark multiple files and generate one \ 
result per file
api : change : when setting pledgedSrcSize, use ZSTD_CONTENTSIZE_UNKNOWN macro \ 
value to mean "unknown"
api : fix : support large skippable frames
api : fix : re-using context could result in suboptimal block size in some \ 
corner case scenarios
api : fix : streaming interface was adding a useless 3-bytes null block to small \ 
frames
build: fix : compilation under rhel6 and centos6
build: added check target
build: improved meson support

Log message:
zstd: update to 1.3.2

v1.3.2
new : long range mode, using --long command
new : ability to generate and decode magicless frames
changed : maximum nb of threads reduced to 200, to avoid address space \ 
exhaustion in 32-bits mode
fix : multi-threading compression works with custom allocators
fix : ZSTD_sizeof_CStream() was over-evaluating memory usage
fix : a rare compression bug when compression generates very large distances and \ 
bunch of other conditions (only possible at --ultra -22)
fix : 32-bits build can now decode large offsets (levels 21+)
cli : added LZ4 frame support by default
cli : improved --list output
cli : new : can split input file for dictionary training, using command -B#
cli : new : clean operation artefact on Ctrl-C interruption
cli : fix : do not change /dev/null permissions when using command -t with root \ 
access
cli : fix : write file size in header in multiple-files mode
api : added macro ZSTD_COMPRESSBOUND() for static allocation
api : experimental : new advanced decompression API
api : fix : sizeof_CCtx() used to over-estimate
build: fix : no-multithread variant compiles without pool.c dependency
build: better compatibility with reproducible builds
example : added streaming_memory_usage
license : changed /examples license to BSD + GPLv2
license : fix a few header files to reflect new license
