Red Hat Enterprise Linux (RHEL) 8.1 released

On November 6th, 2019 Red Hat announced RHEL 8.1 the first service pack for their new enterprise version. 

The kernel level for 8.1 is kernel-4.18.0-147.el8. This is a bug fix and feature release. On System Z RHEL 8.1 is better consumable and quite a few new features have been added. One of the most prominent ones is the extension of the so called “Application Streams” and modules. In one module you can have different streams (those are really versions) of the same package. Red Hat has created separate documentation for using the Application Streams. 
On top there are also  System Z specific features:

  • In place upgrade from RHEL 7.x to RHEL 8.1 for System Z (update to RHEL 8 is not supported)
  • The upcoming secure boot feature of z15 is supported
  • New tool zcyptstats to monitor usage of the cryptographic cards
