Zstandard v1.4.2

Legacy Decompression Fix

This release is a small one, that corrects an issue discovered in the previous \ 
release. Zstandard v1.4.1 included a bug in decompressing v0.5 legacy frames, \ 
which is fixed in v1.4.2.

Detailed Changes

bug: Fix bug in zstd-0.5 decoder
bug: Fix seekable decompression in-memory API
bug: Close minor memory leak in CLI
misc: Validate blocks are smaller than size limit
misc: Restructure source files

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 1.3.5

Zstandard v1.3.5 is a maintenance release focused on dictionary compression \ 
performance.

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.
