There is new a module containing Persistent Memory Development Kit (PMDK):

  • IPsec VPN provided by Libreswan now supports TCP encapsulation and security labels for IKEv2.
  • The OpenSCAP packages have been rebased to version 1.3.4, scap-security-guide has been rebased to version 0.1.54.
  • The fapolicyd framework now provides integrity checking, and the RPM plugin now registers any system update handled by either the YUM package manager or the RPM Package Manager.

General updates and improvements

  • EuroLinux 8.4 offers now Subversion 1.14. It's packed as the module subversion with stream 1.14. The 1.10 stream remain the default module that contains this package.
  • New module eclipse. This module has Eclipse IDE but is commonly used to build Java related packages.
  • The nmstate packages provide a library and the nmstatectl command-line utility to manage host network settings declaratively. Nmstate is a network API for hosts and is fully supported in EuroLinux 8.4. The Multi-protocol Label Switching (MPLS) is an in-kernel data-forwarding mechanism to route traffic flow across enterprise networks.
  • The iproute2 utility introduces three new traffic control actions.
  • EuroLinux 8 kernel now uses proactive compaction that regularly initiates memory compaction work before a request for an allocation is made. Therefore, latency for specific memory allocation requests is lowered.
  • EuroLinux 8 kernel has now a new implementation of a slab memory controller for control groups.
  • EuroLinux kernel now supports the time namespace feature. It allows changing date and time inside the Linux containers.
  • EuroLinux 8 kernel now supports the Error Detection and Correction (EDAC) in 8th and 9th generation Intel Core Processors.
  • There are changes in the pacemaker resource agent - it now can detect failures asynchronously and inject a failure into Pacemaker immediately without waiting for the following monitor interval.

How to update from beta

The beta repository has an updated package el-release, that contains production repositories. Upgrading from EuroLinux 8.4 beta to 8.4 is as simple as running:

sudo yum update -y el-release
sudo yum update -y
