Chapter 1. Overview

1.1. Major changes in RHEL 10.0 Beta

Key highlights for RHEL installer:

  • The newly created users will have administrative privileges by default, unless you deselect the option.
  • You can now set the required time zone by using new options instead of the time zone map.
  • The remote desktop protocol (RDP) for graphical remote access replaces VNC.

Key highlights for RHEL image builder:

  • Disk images, such as AWS or KVM, do not have a separate /boot partition.

For more information, see New features and enhancements - Installer and image creation.

Security

As a Technology Preview, system-wide cryptographic policies (crypto-policies), the OpenSSL TLS toolkit, and the OpenSSH suite now work with post-quantum (PQ) algorithms.

With the new sudo RHEL system role, you can consistently manage sudo configuration at scale across your RHEL systems.

RHEL 10 introduces Sequoia PGP tools sq and sqv that complement the existing GnuPG tools for managing OpenPGP encryption and signatures.

The OpenSSL TLS toolkit introduces creation of FIPS-compliant PKCS #12 files, the pkcs11-provider for using hardware tokens, and many additional improvements.

RHEL 10 contains the OpenSSH suite in version 9.8, which provides many fixes and improvements over OpenSSH 8.7 which was provided in RHEL 9.

The SELinux userspace release 3.7 introduces a new option for audit2allow providing CIL output mode, Wayland support for the SELinux sandbox, and other improvements.

The Keylime agent component is provided in version 0.2.5, which provides support for Initial Device Identity (IDevID) and Initial Attestation Key (IAK) for device identity and uses TLS 1.3 by default.

The security compliance offering has evolved substantially compared to RHEL 9 in both the tooling and content. You can still perform all the actions you need to bring your systems close to a compliant state although you might need to use different tools than in previous versions of RHEL.

See New features - Security for more information.

Identity Management

Key highlights for Identity Management:

  • The IdM server functions only partially or not at all. Specifically, you cannot install the ipa-server-dns package, and the embedded DNS server cannot be configured using the -setup-dns option. Until the necessary updates to bind-dyndb-ldap and other impacted components are completed, the integrated DNS feature remains unavailable.

See Known Issues - Identity Management for more information.

The web console

With the new File browser provided by the cockpit-files package, you can manage files and directories in the RHEL web console.

See New features - The web console for more information.
