The newest release: AlmaLinux 9.3 Beta – What are the updates?

The Beta of AlmaLinux 9.3 has been unveiled on October 26, 2023. It supports the following platforms:

– x86_64
– aarch64
– ppc64le
– s390x

Codename: Shamrock Pampas Cat.

Distributed kernel version: 5.14.0-362.2.1.el9_3

warning: This is a BETA release and should not be used for production installations. The provided upgrade instructions should not be used on production machines unless you don’t mind if something breaks.

AlmaLinux is an open-source, community-backed project built from the source code of Red Hat Enterprise Linux (RHEL).

It’s fully binary-compatible with RHEL and is led by the developers of CloudLinux OS. The AlmaLinux team has promised the public that the AlmaLinux operating system will remain forever free, always open source, with no restrictions, completely free of charge.

In 2020, Red Hat chose not to continue CentOS Linux as an independent distribution but rolled out the rolling update CentOS Stream, considering it as the precursor version of the enterprise-level RHEL.

Following this decision, the community swiftly launched several projects to replace CentOS, of which the two most prominent are Rocky Linux, supported by the Rocky Enterprise Software Foundation, and AlmaLinux, backed by the AlmaLinux OS Foundation.

This new version introduces advanced security features and operational status check tools for containers and virtual machines. Additionally, it offers the required flexibility, stability, and reliability for hybrid clouds.

The official announcement mentioned:

  • The goal of AlmaLinux 9.3 Beta is to enhance flexibility, reliability, and increase security in hybrid environments. This version further simplifies automation and system management.
  • The enhanced Web console makes management tasks more convenient. Moreover, users can set operational status to check the behavior of Podman containers and vsock devices in virtual machines.
  • The update of Application Streams offers developers more flexibility and customization options while ensuring stable platform operation.

No. They pull updates from the Centos stream but are matching releases with RHEL.
