Branch: CURRENT, Version: 1.4.5, Package name: zstd-1.4.5, 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.

Zstd v1.4.5 Release Notes

This is a fairly important release which includes performance improvements and \ 
new major CLI features. It also fixes a few corner cases, making it a \ 
recommended upgrade.

perf: Automatically downsizes ZSTD_DCtx when too large for too long
perf: Improved fast compression speed on aarch64
perf: Small level 1 compression speed gains (depending on compiler)
fix: Compression ratio regression on huge files (> 3 GB) using high levels \ 
(--ultra) and multithreading, by @terrelln
api: ZDICT_finalizeDictionary() is promoted to stable
api: new experimental parameter ZSTD_d_stableOutBuffer
build: Generate a single-file libzstd library

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 v1.4.3

Dictionary Compression Regression
We discovered an issue in the v1.4.2 release, which can degrade the \ 
effectiveness of dictionary compression. This release fixes that issue.

Detailed Changes
* bug: Fix Dictionary Compression Ratio Regression
* bug: Fix Buffer Overflow in v0.3 Decompression
* build: Add support for IAR C/C++ Compiler for Arm

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
