Description

zlib-ng is a zlib replacement with optimizations for "next generation" systems. It is a drop-in replacement (ZLIB_COMPAT mode) for the standard zlib library, providing substantial performance improvements through SIMD acceleration (SSE2/SSSE3/SSE4/AVX2/AVX512 on x86_64; NEON on aarch64) and modern deflate/inflate strategies. This package installs into an isolated directory and uses ld.so.conf.d to take precedence over the system zlib at runtime, without replacing it on disk. Existing installs of the deprecated intel-zlib and cloudflare-zlib packages are obsoleted on upgrade.

Built for AlmaLinux, Rocky Linux, Oracle Linux and RHEL.
