🥇Red Hat Enterprise Linux 8

At Red Hat Summit 2019, a new version of the RHEL distribution based on Fedora 28 was introduced. This release is the last in the series created without the direct involvement of Red Hat's owner — IBM.

Notable new features include:

Wayland is now the default protocol for the GNOME desktop environment.
Application Streams — a system for delivering different versions of software (in the form of modules and rpm packages).
YUMv4 — the new version of the package manager is now based on DNF technology and supports working with modular software.
Support for LUKS2 encryption is enabled by default in the Anaconda installer.
Cryptographic rules are applied by default. Support for TLS 1.2 and 1.3, IKEv2, and SSH2 protocols is available.
nftables is now included by default instead of iptables.
A firewall configuration page has been added to Cockpit (a web interface for server management).
