1 About the release notes

These Release Notes are identical across all architectures, and the most recent version is always available online at https://www.suse.com/releasenotes.

Entries are only listed once but they can be referenced in several places if they are important and belong to more than one section.

Release notes usually only list changes that happened between two subsequent releases. Certain important entries from the release notes of previous product versions are repeated. To make these entries easier to identify, they contain a note to that effect.

However, repeated entries are provided as a courtesy only. Therefore, if you are skipping one or more service packs, check the release notes of the skipped service packs as well. If you are only reading the release notes of the current release, you could miss important changes.

2.2 What Is New?

2.2.1 General Changes in SLE 15

SUSE Linux Enterprise Desktop/SUSE Linux Enterprise Workstation Extension 15 introduces many innovative changes compared to SUSE Linux Enterprise Desktop/SUSE Linux Enterprise Workstation Extension 12. The most important changes are listed below.

Migration from openSUSE Leap to SUSE Linux Enterprise Desktop/SUSE Linux Enterprise Workstation Extension

Starting with SLE 15, we support migrating from openSUSE Leap 15 to SUSE Linux Enterprise Desktop/SUSE Linux Enterprise Workstation Extension 15. Even if you decide to start out with the free community distribution you can later easily upgrade to a distribution with enterprise-class support.

Extended Package Search

Use the new Zypper command zypper search-packages to search across all SUSE repositories available for your product even if they are not yet enabled. This functionality makes it easier for administrators and system architects to find the software packages needed. To do so, it leverages the SUSE Customer Center.

Software Development Kit

With SLE 15, the Software Development Kit is now integrated into the products. Development packages are packaged alongside regular packages. In addition, the Development Tools module contains tools for development.

RMT Replaces SMT

SMT (Subscription Management Tool) has been removed. Instead, RMT (Repository Mirroring Tool) now allows mirroring SUSE repositories and custom repositories. You can then register systems directly with RMT. In environments with tightened security, RMT can also proxy other RMT servers.

2.2.2 Changes in 15 SP3

SUSE Linux Enterprise Desktop/SUSE Linux Enterprise Workstation Extension 15 SP3 introduces changes compared to SUSE Linux Enterprise Desktop/SUSE Linux Enterprise Workstation Extension SP2. The most important changes are listed below.

Media Changes

The Unified Installer and Packages DVDs known from SUSE Linux Enterprise Desktop/SUSE Linux Enterprise Workstation Extension 15 SP1 are deprecated and have been replaced by the following media:

  • Online Installation Media: All SUSE Linux Enterprise 15 products can be installed with this stand alone media, after entering a registration key. The necessary packages are fetched from online repositories only. For information about available modules, see Section 3.1, “Modules in the SLE 15 SP3 Product Line”.

  • Full Installation Media: All SUSE Linux Enterprise Desktop/SUSE Linux Enterprise Workstation Extension 15 products can be installed without network connection with this media, for offline installation scenarios. The media contains all necessary packages. It consists of directories with module repositories which need to be added manually as needed. RMT (Repository Mirroring Tool) and SUSE Manager provide additional options for disconnected or managed installation.

Kernel

SLE 15 SP3 includes the Linux 5.3 kernel. This new kernel release includes upstream features such as 16 million additionally usable IPv4 addresses, utilization clamping support in the task scheduler, power-efficient userspace waiting with the umwait x86 instructions and many more.

If you test a technology preview, contact your SUSE representative and let them know about your experience and use cases. Your input is helpful for future development.

Technology previews come with the following limitations:

  • Technology previews are still in development. Therefore, they may be functionally incomplete, unstable, or in other ways not suitable for production use.

  • Technology previews are not supported.

  • Technology previews may only be available for specific hardware architectures. Details and functionality of technology previews are subject to change. As a result, upgrading to subsequent releases of a technology preview may be impossible and require a fresh installation.

  • Technology previews can be removed from a product at any time. This may be the case, for example, if SUSE discovers that a preview does not meet the customer or market needs, or does not comply with enterprise standards.

6 General Features & Fixes

6.1 Desktop

6.1.1 The laptop RPM pattern has been renamed to mobile

The RPM pattern laptop which was used to install laptop-relevant packages has been renamed to mobile.

If you are using an AutoYaST profile, it may have to be updated after this change. The mobile pattern has also been cleaned up to remove duplicated and obsolete requirements.

6.1.2 Flatpak has been updated to version 1.10

Flatpak has been updated to version 1.10.1. This update allows installing Chromium-based web browsers and adds support for new repository format, that enables faster updates and downloads less data.

6.1.3 Support for StrongSwan in NetworkManager has been added

Support for StrongSwan (IPSec VPN) is now available when using NetworkManager. You need to install the NetworkManager-strongswan package, and NetworkManager-strongswan-gnome if using the GNOME desktop. Then to set up the VPN, use the NetworManager configuration tool.

6.1.4 Remmina has been updated to version 1.4.8

The Remmina remote desktop client has been updated to version 1.4.8. This version provides UDP RDP support, among many new features and bug fixes. Freerdp was updated to version 2.1.2.

6.2 Base System

6.3 Virtualization

7 Known Issues & Workarounds

This is a list of known issues for this release.

7.1 Enabling GNOME Session Restore Does Not Work

You can have GNOME restore your previous desktop session when logging in. In the past, this could be achieved by enabling the dconf entry /org/gnome/gnome-session/auto-save-session. In GNOME 3.34, the upstream GNOME project disabled this functionality because it caused issues under newer versions of systemd. As SUSE Linux Enterprise Desktop/SUSE Linux Enterprise Workstation Extension uses GNOME 3.34, the functionality cannot be used in SUSE Linux Enterprise Desktop/SUSE Linux Enterprise Workstation Extension 15 SP3 anymore.
