\fBzstd\fR offers \fIdictionary\fR compression, which greatly improves efficiency on small files and messages\. It\'s possible to train \fBzstd\fR with a set of samples, the result of which is saved into a file called a \fBdictionary\fR\. Then during compression and decompression, reference the same dictionary, using command \fB\-D dictionaryFileName\fR\. Compression of small files similar to the sample set will be greatly improved\.

.SS "Restricted usage of Environment Variables"

Using environment variables to set parameters has security implications\. Therefore, this avenue is intentionally restricted\. Only \fBZSTD_CLEVEL\fR and \fBZSTD_NBTHREADS\fR are currently supported\. They set the compression level and number of threads to use during compression, respectively\.

- update to 1.5.1:
|
||||
* perf: rebalanced compression levels, to better match the intended speed/level curve
|
||||
* perf: faster huffman decoder, using x64 assembly
|
||||
* perf: slightly faster high speed modes (strategies fast & dfast)
|
||||
* perf: improved binary size and faster compilation times
|
||||
* perf: new row64 mode, used notably in level 12
|
||||
* perf: faster mid-level compression speed in presence of highly repetitive patterns
|
||||
* perf: minor compression ratio improvements for small data at high levels
|
||||
* perf: reduced stack usage (mostly useful for Linux Kernel)
|
||||
* perf: faster compression speed on incompressible data
|
||||
* perf: on-demand reduced ZSTD_DCtx state size, using build macro ZSTD_DECODER_INTERNAL_BUFFER, at a small cost of performance
|
||||
* build: allows hiding static symbols in the dynamic library, using build macro
|
||||
* build: support for m68k (Motorola 68000's)
|
||||
* build: improved AIX support
|
||||
* build: improved meson unofficial build
|
||||
* cli : custom memory limit when training dictionary (#2925)
|
||||
* cli : report advanced parameters information when compressing in very verbose mode (``-vv`)
