The new version of Red Hat Enterprise Linux 8.1 has been released, know its news

Red Hat has announced the release of the new version of your Linux distribution, «Red Hat Enterprise Linux 8.1«, This being the first version prepared according to a new predictable development cycle, which implies the formation of versions every six months at a predetermined time. Accurate information on when a new version will be released allows you to synchronize development schedules for various projects, prepare in advance for a new release, and schedule the time for applying updates.

The new life cycle of RHEL products covers several levels, including Fedora as a bridgehead for the implementation of new features, CentOS Stream to access packages formed for the upcoming RHEL Intermediate Release (RHEL Rolling Release), a Minimalist Universal Base Image (UBI, Universal Base Image)) for running applications in isolated containers, and RHEL Developer Subscription for free use of RHEL on the development process.

What's new in Red Hat Enterprise Linux 8.1

With the release of this new version full support is provided for the Live-patching (kpatch) mechanism to eliminate vulnerabilities in the Linux Kernel without rebooting the system and without stopping the work. Previously, kpatch was in the category of experimental features.

Added a new SELinux type: boltd_t, which restricts boltd, a process for managing devices with a Thunderbolt 3 interface (boltd now runs in a SELinux-limited container). Added a new SELinux rule class: bpf, which controls access to the Berkeley Packet Filter (BPF) and inspects applications for eBPF.

The framework includes SELinux profiles, focused on use with isolated containers and allowing more controlled access to services that run in containers to host system resources.

To generate SELinux rules for containers, a new Udic utility, which allows, taking into account the specific characteristics of a particular container, provide access only to necessary external resources such as stores, devices, and the network. The SELinux utilities (libsepol, libselinux, libsemanage, policycoreutils, checkpolicy, mcstrans) have been updated to version 2.9 and the SETools package to version 4.2.2.

In the classic session of Gnome Classic, the virtual desktop switch is changed. The widget for switching between desktops is now on the right side of the bottom panel and is designed as a strip with desktop thumbnails (to switch to another desktop, simply click on the thumbnail that reflects its content).

As well Updated versions of OpenSSH 8.0p1, Tuned 2.12, chrony 3.5, samba 4.10.4. Modules have been added with the new branches PHP 7.3, Ruby 2.6, Node.js 12 and nginx 1.16 to the AppStream repository (update of modules with previous branches has continued). Packages added with GCC 9, LLVM 8.0.1, Rust 1.37 and Go 1.12.8 to the software collection.

The SystemTap trace toolkit has been updated to branch 4.1, and the Valgrind memory debugging toolkit has been updated to version 3.15.

The dnf-utils package has been renamed to yum-utils for compatibility (The ability to install dnf-utils is preserved, but this package will be automatically replaced by yum-utils).

The DRM subsystem (Direct Rendering Manager) and low-level graphics drivers (amdgpu, nouveau, i915, mgag200) they have been updated to the state corresponding to the Linux 5.1 kernel. Added support for the AMD Raven 2, AMD Picasso, AMD Vega, Intel Amber Lake-Y, and Intel Comet Lake-U video subsystems.

A new edition of Red Hat Enterprise Linux System Roles has been added, which provides a set of modules and roles to implement a centralized Ansible-based configuration management system and configure subsystems to use specific functions related to storage, network capabilities, time synchronization, SElinux rules, and the use of the kdump mechanism.

For example, the new storage feature allows you to perform tasks such as managing FS on disk, working with LVM groups, and logical partitions.

Installation builds are prepared for the architectures x86_64, s390x (IBM System z), ppc64le, and Aarch64, but they are available for download only to registered users of the Red Hat Customer Portal.
