Branch: CURRENT, Version: 1.4.4, Package name: zstd-1.4.4, Maintainer: pkgsrc-users

Zstd, short for Zstandard, is a fast lossless compression algorithm,
targeting real-time compression scenarios at zlib-level and better
compression ratios.

Log message:
all: migrate several HOMEPAGEs to https

pkglint --only "https instead of http" -r -F

With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.

This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.

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
