The Red Hat organization has finally completed the next maintenance update for the upcoming Red Hat Enterprise Linux 8.2, whose beta version is now available for download.
As Red Hat sysadmin Christian Labisch mentioned, the capability to register your system, add RHEL subscriptions, and install from the Content Delivery Network (CDN) before package installation is “a tremendous improvement.”
You can use this release with both interactive GUI installations and automatic Kickstart installations. It arises with a host of advantages such as:
- A smaller Boot ISO image file replaces the need to download the more comprehensive Binary DVD ISO image file.
- The CDN uses the most advanced packages that appear in a fully subscribed and current system directly after installation. There is no obligation to install package updates after installation. This reduces the need to do a YUM update straight after installation to establish a registered RHEL subscription.
- Registration is done before package installation, following in a more precise and more smooth installation process.
- Integrated support for Red Hat Insights, a service that proactively detects and remediates menaces, is available.

Open Source Developer Tools
RHEL 8.2 beta rises the open-source developer tools such as GCC Toolset 9.1, Maven 3.6, Python 3.8 to its most modern versions, which are available through the concept of Application Streams that were offered by the Red Hat Team in RHEL 8 series.
The new Beta also prolongs RHEL’s monitoring and performance skills with the introduction of Performance Co-Pilot (PCP) 5.02. This now occurs with new collection agents for Microsoft SQL Server 2019 on Linux.
For programmers, 8.2 adds a tighter combination with the extended Berkeley Packet Filter (eBPF). This is an in-kernel implicit machine that provides code performance in the kernel space.
On other platforms, eBPF is previously being used for a wide variety of tasks. In RHEL 8.2, you’ll be capable of handling the following eBPF components:
- The BPF Compiler Collection (BCC) tools package is a userspace array of powerful kernel tracing services that practice the eBPF virtual machine for developing efficient kernel tracing and administration programs. BCC implements tools for I/O networking, analysis, and monitoring of Linux running systems using eBPF.
- The BCC library which encourages the development of tools related to those provided in the BCC tools package.
- The eBPF for the TC feature allows programmable package processing inside the kernel network data path.
The developing eBPF elements are prepared as a Technology Preview:
- The bpftrace tracing language
- The eXpress Data Path (XDP) trait
Red Hat has continued supported language updates ahead of RHEL releases in the before-mentioned packages as Red Hat Software Collections. In RHEL 8, Application Streams made the latest developer languages, runtimes, and different tools to RHEL. This provides your programmers access to the latest tools while maintaining the primary operating system release stability.
