Stability plus innovation: Red Hat Enterprise Linux 8.4 is now GARed Hat Enterprise Linux (RHEL) 8.4 is generally available to customers as of May 19, 2021. Delivered as part of the predictable, six-month cadence of RHEL releases 8.4 brings important features for hybrid cloud, edge deployments and enhancements for operators, developers and organizations standardized on RHEL.
RHEL at the EdgeWith RHEL 8.3 we announced a deployment option for RHEL to help solve challenges common to edge computing environments. With 8.4, we have built on that work to improve the user experience around the edge computing capabilities in RHEL.
RHEL 8.4 simplifies updates, provides additional options for installing to disconnected systems (as many edge systems are) and adds the ability to use OSTree repositories with OCI container images. Read about the improvements in Ben Breard's post on new edge features for 8.4.
Red Hat InsightsA Red Hat Enterprise Linux subscription is so much more than the bits that make up a RHEL release. It's the ecosystem that surrounds RHEL, the services like Red Hat Insights, the extensive documentation, the certifications and much more.
We were pleased to announce in late April that we've expanded Insights to help provide a holistic view across your IT environments and into Red Hat OpenShift and Red Hat Ansible Automation Platform.
Hybrid cloud your wayOne of the things we've worked on in conjunction with the 8.4 release is simplifying our Cloud Access program, making it easier to consume content when deploying cloud-based systems and manage them using the Insights ecosystem. Read all about our improvements and new features around doing hybrid cloud your way with RHEL 8.4.
Much more in 8.4
- RHEL 8.4 comes with the Container Tools 3.0 AppStream, which contains newer versions of Podman, Buildah, Skopeo and runc.
- Podman now has support in RHEL for auto-updating container images, which allows Podman to poll to see if containers have been updated and pull new images and use systemd to restart them if there is a new image.
- This release also sees the addition of the Red Hat Universal Base Image (UBI) micro image. This is the smallest UBI offering that omits package management from the image itself, but can rely on a package manager on the underlying RHEL host to install packages.
- Naturally, we have introduced new AppStreams for our customers with 8.4, including Python 3.9, Redis 6, PostgreSQL 13, MariaDB 10.5 as well as GCC 10, LLVM 11, Rust 1.49 and Go 1.15.7.
- Intel Tiger Lake GPUs are now supported in RHEL 8.4, which includes Intel UHD graphics and Intel Xe integrated GPUs.
- RHEL 8.4 introduces two new system roles. First, a new Reliable Event Logging Protocol (RELP) system role for forwarding or receiving rsyslog log messages with RELP. We also have introduced an SSH Client system role to help configure RHEL SSH in a consistent and stable manner for SSH servers and clients.
