After a year of development, SUSE release of the industrial distribution SUSE Linux Enterprise 15 SP2. SUSE 15 SP2 packages are already as a base in a community supported distribution . Based SUSE Linux Enterprise also formed products such as , , SUSE Manager and SUSE Linux Enterprise High Performance Computing. Distribution can be and is free to use, but access to updates and patches is limited to a 60-day trial period. The release is available in builds for the aarch64, ppc64le, s390x, and x86_64 architectures.
:
- Instead of a unified set of installation DVDs, a minimal image for online installation and a full installation image for installation on systems without network access are offered.
- GNOME desktop updated to version (previously had GNOME 3.26). Updated many user applications and libraries, including Qt 5.12, Gstreamer 1.16.2.
- Support for PRIME technology has been backported to the X server, which on systems with two GPUs allows you to display the base session on the integrated GPU, and in some applications use a discrete graphics card.
- Support has been dropped for User Space (UMS)-only graphics drivers. Only KMS-enabled drivers are left.
- Systemd has ported support for filtering traffic in relation to services, which allows using the IPAddressAllow and IPAddressDeny options to define lists of allowed and denied IP addresses and subnets, forming a simple access control system (restrictions apply to both incoming and outgoing traffic).
- For the x86_64 and AArch64 architectures, Vagrant Boxes are provided, the minimum packages for creating compact virtual environments for libvirt and VirtualBox using the Vagrant toolkit.
- Linux kernel updated to release (previously proposed kernel 4.12). A variant of the kernel-preempt kernel with Real-Time patches for real-time systems has been provided.
- Updated PostgreSQL 12 and MariaDB 10.4 DBMS versions. Added support for Libxml++ and Maven 3.6.2 libraries. RabbitMQ Server 3.8.3 is included. Updated LLVM 9, PHP 7.4, Wireshark 3.2, Salt 3000, Xen 4.13, libvirt 6.0.x,
- AppArmor updated to release , which adds support for profile precompilation and caching for faster loading.
- Added plugins for HP (hpsa) and LSI (megaraid) hardware to libstoragemgmt.
- Network support removed from YaST
PCMCIA,
token ring,
FDDI
myrinet,
arcnet,
xp (IA64 specific) and
ESCON (specific to IBM Z). The YaST module for the NTP client has been moved to the systemd-timer setting instead of cron. Moved sysctl settings to /etc/sysctl.d/70-yast.conf. - Added "--repo" option to "zypper download" command to specify repository to download packages. The Snapper plugin for Zypper has been rewritten from Python to C.
- Implemented support for new hardware, including new Intel platforms, Fujitsu A64FX, AMD EPYC, NVIDIA Tegra X1/X2 and Raspberry Pi 4.
- For ARM64 systems with Vivante GPUs (NXP Layerscape LS1028A/LS1018A and NXP i.MX 8M SoCs), the etnaviv graphics driver has been added, and for SoCs with Mali-400e GPUs (Xilinx Zynq UltraScale), the lima driver has been added. Added mali-dp driver for Mali-DP500 screen control chips used in NXP Layerscape LS1028A/LS1018 SoC.
- The U-Boot bootloader for Raspberry Pi boards (package u-boot-rpiarm64) includes experimental support for the Btrfs file system, which allows you to access Btrfs partitions directly from the bootloader and boot the kernel from them without having to run GRUB from a FAT partition. U-Boot boot scripts have been reorganized.
- For x86_64 systems, experimental support has been added for a CPU idle handler called βhaltpollβ, which decides when the CPU can be put into deep power saving modes, the deeper the mode, the greater the savings, but also the longer it takes to exit the mode. The new handler is designed for use in virtualization systems and allows the virtual CPU (VCPU) used in the guest system to request additional time before the CPU is put into the idle state. This approach improves the performance of virtualized applications by preventing control from returning to the hypervisor.
- Added toolkit support for managing isolated containers
- XFS provides support for the reflink mechanism (previously only supported in Btrfs), which allows you to clone file metadata by creating a link to existing data without actually copying it.
- Discontinued support for squashfs 3.x partitions (kernel only supports squashfs 4.0 now).
- Added driver to enable EDAC (Error Detection and Correction) in AMD Zen 3 processors.
- Removed support for the legacy microcode load interface (/dev/cpu/microcode).
- Most packages include support for TLS 1.3.
- The BIND, nginx, and wireshark packages have been migrated to use the GeoLite2 address-to-location base and the libmaxminddb library instead of the deprecated GeoIP base, which is no longer supported.
- Provides an option to quickly migrate openSUSE server and desktop installations to the production SUSE Linux Enterprise distribution, allowing system integrators to build and test a working openSUSE-based solution first, and then switch to a commercial version with full support, SLA, certification, long-term updates, and advanced means for mass adoption. For SUSE Linux Enterprise users, the SUSE Package Hub is available to provide access to additional applications and new releases supported by the openSUSE community. It is noted that compared to the last release, the differences in the package base between SUSE and openSUSE have been reduced by 75%.
