1. Course Overview & Purpose

The RH304 course, titled “New Features in Red Hat Enterprise Linux", is designed to help experienced Linux professionals make full use of Red Hat Enterprise Linux 10. This training covers the most impactful enhancements and variant updates introduced in RHEL 10, preparing you to adopt new capabilities efficiently.

Participants gain hands-on exposure to installation optimizations, AI-enhanced system guidance via Lightspeed, container upgrades, Flatpak integration, and immersive image-based systems. The goal: move past installation basics and mastery of advanced, enterprise-ready RHEL 10 features.

2. What Are the Target Audience & Prerequisites?

Ideal attendees are:

• System administrators
• Platform engineers
• DevOps professionals
• Linux developers

All should have working knowledge of RHEL 9 or earlier, and familiarity with tasks such as package management, system services, and basic scripting

Prerequisites include:

• RH124 and RH134 training (or equivalent hands-on RHEL 9 experience)
• Comfort with configuring storage, users, roles, containers
• Access to an RHEL 10 lab environment (virtual or physical)

These prerequisites ensure learners focus on new features rather than foundational tasks like partition setup or network configuration.

3. What Are the Core Topics & New Features?

RH304 covers five core feature sets in a structured way:

1. Installation & Kickstart Changes
2. AI‑Driven Guidance with RHEL Lightspeed
3. Flatpak Integration
4. Container Management Updates
5. Image‑Based Installations & Upgrades

These topics are essential for administrators ready to harness RHEL 10 in modern DevOps, edge and hybrid‑cloud scenarios

3.1 Installation & Kickstart Changes

RH304 teaches both interactive and scripted installs of RHEL 10. The course highlights improvements in Kickstart support, enabling administrators to build immutable, Golden‑Image prototypes. It emphasizes how Kickstart directives now control new hardware detection, AI‑ready system pre‑configuration, and secure default profiles more effectively

3.2 AI‑Driven Guidance with RHEL Lightspeed

A core highlight is RHEL Lightspeed, the operating‑system‑integrated AI assistant that helps with diagnostics, tuning, and best‑practice prompts. Instructors will demonstrate real‑time scenario guides, from optimizing memory allocation to patch advisories, all via contextual AI feedback 

3.3 Flatpak from Red Hat Ecosystem Catalog

Installation and management of desktop applications using Flatpak are covered in detail. RH304 shows how to add the Red Hat Ecosystem Catalog, install, update, and remove Flatpaks, and manage sandbox policies, all with enterprise governance in mind 

3.4 Container Management Updates (Podman)

Container tooling in RHEL 10 has matured, and RH304 delivers hands‑on exercises using Podman and Buildah. Participants build, sign, run, and manage container images, including advanced features for rootless containers, integrated security policies, and multi‑stage image builds 

3.5 Image‑Based Installation Management

Image‑based techniques let you install or upgrade RHEL 10 using pre-built OS images. RH304 covers custom image construction for cloud, container, edge deployments, and live upgrades. Students learn how to script deployable artifacts with system roles and manage version rollbacks 

4. What Are the Course Outcomes & Benefits?

By completion, students will:

• Understand significant differences between RHEL 9 and 10
• Master AI assistant-driven recommendations
• Install/manage desktop software with Flatpak securely
• Build lightweight containers with modern OCI tools
• Deploy using immutable or Gold‑Image methods

These outcomes enable real-world productivity gains, faster troubleshooting, standardization, and adoption of new features, useful for teams running cloud services, automation, or edge fleets

5. Training Formats & Delivery

RH304 is offered in:

• Instructor-led classroom sessions
• Virtual training via streaming platforms
• On‑site corporate delivery for teams

Hands‑on labs reinforce learning, and Red Hat Learning Subscription owners can take lab modules at their own pace

6. Recommended Next Courses & Certification

After RH304, students are advised to proceed to RH294, Red Hat Enterprise Linux Automation with Ansible to build on their new platform skills 

8. Conclusion

RH304: New Features in Red Hat Enterprise Linux is an advancement course for professionals ready to transition to RHEL 10. It prepares you to use:

• Installation enhancements
