b83d1e7714 removed some static const variables 
and replaced by traditional macro constants.

Unfortunately, C doesn't consider `static const` to mean "constant"

a54c86cfc6 defined a minimum negative level 
which can be probed using new function ZSTD_minCLevel().

Also : redefined ZSTD_TARGETLENGTH_MIN/MAX for consistency

used the opportunity to bump version number to v1.3.6

105677c6db created ZSTDMT_toFlushNow() 
tells in a non-blocking way if there is something ready to flush right now.
only works with multi-threading for the time being.

Useful to know if flush speed will be limited by lack of production.

c2c47e24e0 support targetlen==0 with strategy==ZSTD_fast 
to mean "normal compression",
targetlen >= 1 now means "disable huffman compression of literals"
 2018-06-07 15:49:01 -07:00

a57b4df85f removed literalCompression directive 
in this version, literal compression is always disabled for ZSTD_fast strategy.

Performance parity between ZSTD_compress_advanced() and ZSTD_compress_generic()

153bc1c004 removed limit ZSTD_TARGETLENGTH_MAX 
this makes it possible to specify extremely large negative compression levels,
achieving the side effect as "no compression".

It will also be possible to define larger targetlength for ultra compression mode.

There is no adverse side effect due to removing this limit.
