Rocky Linux 8.4 Released as CentOS Linux Replacement

Rocky Linux announced its first stable release, General Availability of Rocky Linux 8.4 (Green Obsidian), to replace CentOS Linux.

Rocky Linux is a community enterprise operating system designed to be 100% bug-for-bug compatible with Red Hat Enterprise Linux 8.4. It is led by Gregory Kurtzer, the founder of the CentOS project.

The CentOS Linux is going to be discontinued and replaced with CentOS Stream.

Previously, it was “downstream build” that receives patches and updates after the upstream vendor does. In future, it will be an “middle-stream build” between Fedora and Red Hat Enterprise Linux, to test patches and updates before inclusion in the upstream vendor.

So Rocky Linux comes to act as the “downstream build” as CentOS Linux had done previously.

What’s New in Rocky Linux 8.4:

The release includes new modules, including Python 3.9, SWIG 4.0, Subversion 1.14, Redis 6, PostgreSQL 13, MariaDB 10.5.

Compilers and development tools has been updated to GCC 10, LLVM 11.0.0, Rust 1.49.0, and Go 1.15.7.

Others include:

  • IPsec VPN provided by Libreswan now supports TCP encapsulation and security labels for IKEv2.
  • Rebase scap-security-guide to version 0.1.54, OpenSCAP to version 1.3.4 to provide substantial improvements.
  • The fapolicyd framework now provides integrity checking
  • Nmstate API to manage host network settings.
  • Introduced three new traffic control actions in iproute2.
  • Multi-protocol Label Switching (MPLS) to route traffic flow across enterprise networks.
  • Proactive compaction reduces latency for specific memory allocation requests
  • A new implementation of slab memory controller for the control groups technology
