CentOS Linux 8.1 (1911) is here almost four months after the introduction of the CentOS Linux 8 operating system series, which is based on Red Hat’s Red Hat Enterprise Linux 8 operating system series, to add all the new features and improvements implemented upstream in the latest Red Hat Enterprise Linux 8.1 release. Highlights include kernel live patching, a new routing protocol stack called FRR which supports multiple IPv4 and IPv6 routing protocols, an extended version of the Berkeley Packet Filter (eBPF) to help sysadmins troubleshoot complex network issues, support for re-encrypting block devices in LUKS2 while the devices are in use, as well as a new tool for generating SELinux policies for containers called udica.
