SUSE Linux Enterprise 15 SP4
SUSE has announced the release of SUSE Linux Enterprise (SLE) 15 SP4, the fourth service
pack of the company's enterprise-class Linux distribution
designed mainly for developers and administrators to deploy business-critical workloads.
The new service package includes extended search for packages across repositories (even
those not enabled) and 389 Directory Server replaces OpenLDAP.
"The OpenLDAP server (package openldap2, part of the Legacy SLE module) has been removed
from SUSE Linux Enterprise Server 15 SP4.
The OpenLDAP client libraries are widely used for LDAP integrations and are compatible with
389 Directory Server.
Hence, the OpenLDAP client libraries and command-line tools will continue to be supported on SLES
15 to provide an easier transition for customers that currently use the OpenLDAP Server.
To replace OpenLDAP server, SLES includes 389 Directory Server. 389 Directory Server
(package 389-ds) is a fully-featured LDAPv3-compliant server suited for modern environments and
for very large LDAP deployments. 389 Directory Server also comes with command-line tools
of its own.

What's New in SUSE Linux Enterprise 15 SP4
The new service pack includes extended search for packages in repositories (even those not
enabled) and 389 Directory Server replaces OpenLDAP.
The OpenLDAP server (openldap2 package, part of the Legacy SLE module) has been removed
from SUSE Linux Enterprise Server 15 SP4.
OpenLDAP client libraries are widely used for LDAP integrations and are supported by
389 Directory Server.
Therefore, OpenLDAP client libraries and command line tools will continue to be supported in
SLES 15 to provide an easier transition for clients currently using OpenLDAP Server.
To replace the OpenLDAP server, SLES includes the 389 Directory Server. 389 Directory Server
(389-ds package) is a complete LDAPv3 compliant server suitable for modern environments and

notable changes Generally
GNOME 41.x Our default desktop environment has been updated to the latest stable upstream
version available.
Note that to make this possible, we sync many packages (like GTK 4.0) with openSUSE Factory
. Linux Kernel 5.14 : SLE 15 SP4 includes the
Linux kernel 5.14.
Also, as usual, we are backporting a large number of patches to our 5.14 kernel, which
makes our kernel different from the upstream 5.14 version.
SLES base container images ( SLE BCI ) More images will be available at registry.suse.com
Our just enough OS (JeOS) virtual machine images have been renamed to Minimal-VM
Removed and deprecated features Python 2, pam/nss ldap, openldap2-server was removed
from SLE 15 SP4.
And we would like to emphasize that we have some deprecated features in SLE 15 SP4.
They will be removed with the next Service Pack.
With NVIDIA's recent release of its open source GPU kernel-mode driver , SLE 15 SP4 is the
first major Linux distribution to provide it, simplifying
Migration from SLE 11 to SLE 15 SP4 is not supported
Safety Adding SLSA 4 compliance to existing security
certifications: SLE 15 SP4 is the first Linux distribution to deliver packages under Google's
demanding SLSA standard differently, adding an SLSA Level 4 compliant supply chain.
This helps protect against the growing software and supply chain security threats that customers
face today.
AMD SEV-ES (Secure Encrypted Virtualization-Encrypted State) host and guest modes , SLE 15 SP4 is
the first Linux distribution to support AMD SEV-ES, allowing customers to select additional
VM isolation to strengthen security.
Userland Live Patching , our SLE Live Patching product now includes userspace patching capability.
Adding openSSL 3.0.1 Update to systemd v249 and added LUKS2 support
in yast2 to support unlocking LUKS2 partitions with TPM2 and FIDO2.
Languages ​​and Databases Adding PHP 8 and OpenJDK 17
Python: New Python 3 module, including Python 3.10
. This new module will require special handling in case of migration from SLE 15 SP3.
See the entry in the Release Notes.
Removal of Python 2 Module (hence all Python 2 packages) for SLE 15SP4.
See the entry in the Release Notes.
MariaDB 10.6 , which is the current stable version of MariaDN with long-term support.
PostgreSQL 14 is now the default version of PostgreSQL in SLE 15 SP4.
PostgreSQL 13 moved to Legacy Module for migration purposes
and more Adding 64K page size support in addition to
4K page size in KVM for ARM . Adding support for Nvidia Virtual GPU 12.x
and 13.x

SUSE Linux Enterprise 15 SP4 available
SUSE Linux Enterprise 15 SP4 is already among us to continue the evolution of one of the
great distributions oriented to the corporate sector.
In this case we find a system that is synchronized with openSUSE Leap 15.4 , so both share, broadly
speaking, the same technological base.
SUSE Linux Enterprise 15 SP4, from now on SLE 15 SP4, takes care of updating the software
stack.
During its development, 23% of all source code has been updated and has been synchronized
with packages taken from openSUSE Factory.
All of this is in addition to the work of both SUSE's own staff as well as public beta
testers and partners.
The first thing that stands out in SLE 15 SP4 is the inclusion of GNOME 41 as the default
desktop environment for the latest stable release of SUSE Linux Enterprise Desktop (SLED).
The maintainers have synchronized with many openSUSE Factory packages to allow, for example,
the arrival of GTK 4, a toolkit that tries to offer some visual standardization with
libadwaita.
The default kernel is Linux 5.14 , to which SUSE has ported “a large number of patches”
back , so we find ourselves with an implementation that is apparently very far from the official
upstream version.
You know, free software stuff, which allows anyone to modify and redistribute it, and
in the case of Linux, such source code redistribution is mandatory.
Another feature of SLE 15 SP4 is the inclusion of the official NVIDIA open source driver
, making this the first major distribution to supply it through its official channels.
At the time, we already learned that the current state of the driver was of little use in a
desktop context, but possibly the situation is different on servers.
As for containers and virtualization, more SLES Base Containers Images (SLE BCI) images
are available via registry.suse.com and images for Just enough Operating System (JeOS) virtual
machines have been renamed to Minimal-VM.
Some features like Python 2, pam/nss ldap, and openldap2-server have been removed from
SLE 15 SP4.
The case of Python 2 is because this version of the interpreted language has been discontinued
for a long time, while OpenLDAP has been replaced by 389 Directory Server.
At the level of programming languages, as in Leap 15.4, we find PHP 8 and OpenJDK 17
(JDK or Java 17) , while the new Python 3 modules include version 3.10 of the language.
The main open source database management systems present are MariaDB 10.6 , fork of MySQL,
and PostgreSQL 14 , more oriented to compete with corporate solutions on the market.
For security, the novelties are the addition of SLSA 4 compliance to existing security
certifications, being SLE 15 SP4 "the first Linux distribution that delivers packages
under the demanding Google SLSA standard in a clear way "; AMD SEV-ES to enforce virtual
machine isolation; a hot patching infrastructure for applications located in user space; LUKS2
support in YaST 2 ; in addition to OpenSSL 3.0.1.
As system framework is systemd 249.
And so far the most important of SUSE Linux Enterprise 15 SP4.
Those who want to know all the details have available the release notes of the Server
and Desktop editions , which are the most prominent, along with the official press release
and the official announcement .
