On May 16, 2023, Red Hat, acquired by IBM, announced the availability of Red Hat Enterprise Linux 8.8 (RHEL), a new version of the world's leading enterprise Linux platform -- a foundation on which organizations can extend existing applications and run them on bare metal. , virtual, containers and all types of cloud environments.
Red Hat Enterprise Linux 8.8 Now Available
Release date: May 16, 2023
The latest version of Red Hat Enterprise Linux 8
Organizations around the world rely on Red Hat Enterprise Linux (RHEL) as the core of their enterprise IT infrastructure. In a rapidly changing IT environment, they need a flexible, stable foundation to support hybrid cloud innovation, manage applications, and efficiently deploy workloads (sysins) across various environments. RHEL is that foundation, helping organizations operate with confidence and drive innovation.
The latest update for RHEL 8 is now available. With the full official release of RHEL 8, customers can more effectively automate manual tasks, standardize deployments at scale, and simplify day-to-day management of systems.
Red Hat is pleased to announce the availability of Red Hat Enterprise Linux (RHEL) 8.8 and 9.2 . RHEL provides a more flexible and stable foundation to support hybrid cloud innovation, and provides a faster and more consistent experience for deploying applications and critical workloads across physical, virtual, private and public clouds, and edge deployments.
What's new?
RHEL 8.8 and 9.2 bring new features and enhancements to deliver greater consistency and a stronger security posture for the foundation of the open hybrid cloud, delivering faster with less effort across environments Workloads, applications and services.
Key Features and Benefits
Here are some highlights of what's included in RHEL 8.8 and 9.2.
Provides a built-in security layer
Enhancements added in RHEL 8.8 and 9.2 help simplify the way organizations manage security and compliance when deploying new systems or managing existing infrastructure. New features include:
- An available realm RHEL system role (sysin) that allows customers to automate the process of directly integrating RHEL systems with Microsoft Active Directory.
- SCAP configuration files and Ansible content for enhanced system inspection and hardening, compliant with Center for Internet Security (CIS) benchmarks for RHEL 9 (RHEL 9.2 only
Optimize existing edge investments
RHEL makes it easier to deploy workloads to distributed computing systems at the edge, helping compute closer to users and data sources. The platform supports the remote management and monitoring required to deploy hundreds or thousands of edge nodes, and the latest release brings new features, including simplified ignition support in the installer and an additional zero-touch provisioning method for edge systems as FIDO device boards Alternative to Onload (FDO) (RHEL 9.2 only).
Accelerate application development
RHEL 8.8 and 9.2 provide developers with enhancements to the application flow (sysin) through new compilers, runtime languages, databases, and web servers. Improvements in this release include:
- Python 3.11 adds several new features and significantly faster performance.
- A new version of Performance Collaborative Driving (PCP), featuring new analytics tools and the Grafana data visualization platform.
- Nginx 1.22 - the high-performance, lightweight web server, reverse proxy, and load balancer - now includes OpenSSL 3.0 compatibility, hardening against request smuggling and cross-protocol attacks, and Application Layer Protocol Negotiation (ALPN).
- PostgreSQL 15 is a popular open source database with new security features and significant performance improvements.
- Updates were made to the Rust v1.66, Go v1.19, and LLVM v15 toolsets.
Make it easier to automate and standardize systems
Automation and management features in RHEL 8.8 and 9.2 continue to help reduce the complexity of automating manual tasks, standardizing deployments, and simplifying day-to-day management of systems. New features include:
web console
- By default, root account logins are disabled on new RHEL 9.2+ installations. This can be configured via the /etc/cockpit/disallow-users file (RHEL 9.2 only).
- The overall configuration (sysin) is provided with Network Bound Disk Encryption (NBDE) on the root file system using the web console.
- Add a virtual monitor device to a virtual machine (VM), and eject and insert ISO images into a virtual CD-ROM device running on the VM. Additionally, the web console now sets the discard property of newly created VM virtual disks to "unmap", allowing discard requests to be passed to the file system.
- Select common combinations of policies and sub-policies for system-wide encryption policies. System-wide encryption policies ensure that encryption configurations on all supported services configured for a host are sound and follow industry- and site-specific security policies.
- Add or remove groups from a user account. Account pages now offer a new list view that includes groups as well as search and sort functionality.
- Detects and uses the system's dark mode setting, which can be overridden by the user if desired.
RHEL system roles
- The new Podman RHEL system role allows customers to automate the deployment of containers in their environment to save time and improve consistency.
- The new logging RHEL system role allows customers to automatically configure systemd logging (sysin) on RHEL, including the ability to configure persistent systemd logging.
- The new ad_integration RHEL system role helps users automate the process of directly integrating RHEL systems with Microsoft Active Directory.
- Several RHEL system roles (including metrics , nbde_server , vpn , microsoft.sql.server , ha_cluster , logging , postfix , and cockpit ) can now optionally invoke firewall and/or Security-Enhanced Linux (SELinux) system roles to open ports And automatically configure the port label.
- The ha_cluster , logging , microsoft.sql.server , and cockpit RHEL system roles can now call the certificate system role to create the corresponding certificates.
- The microsoft.sql.server RHEL system role now provides operational efficiency, disaster recovery hardening, and support for the latest Microsoft SQL Server releases.
Build system images in a more consistent way
The local version of RHEL Image Builder includes many new security and system configuration options for creating highly customized images, such as:
security configuration
- Apply the OpenSCAP security policy configuration file
- Onboard FIDO device for secure provisioning of edge devices
System Configuration
- Import and export blueprint files
- Append kernel boot parameters
- Enable or disable a service
- Enable or disable firewall rules for ports and services
- Define users and groups
- Define an SSH public key for remote access
- Define time zones and time servers
- Define language and locale
- Define installation device
- Defines URLs to ignite files to provide an additional zero-touch provisioning method for edge systems
Build and design containerized deployments more easily
Podman provides an open source tool for developing, managing, and running containers on Linux systems. New features include:
- Container creation auditing . This provides Podman event tracking, allowing container creation events to be audited. Container creation auditing is suitable for environments with system activity auditing requirements.
- Customize health check actions through Podman . This provides organizations with the option to automate when containers become unhealthy, which is critical for services in remote locations or critical systems.
