After a long year of development, the folks at SUSE has announced the launch of the new version of the distribution "SUSE Linux Enterprise 15 SP2", which its packages have already been used as the basis for the community-supported openSUSE Leap 15.2 distribution.
This new version of the distribution comes with various updates, bug fixes, but above all with some pretty important changes.
SUSE Linux Enterprise 15 SP2 Key New Features
Of the main novelties that we can find in this new version are the Linux kernel version 5.3 (previously a 4.12 kernel was offered) with which a realtime Live Patching preference is provided, as well as the update of GNOME to version 3.34 (formerly GNOME 3.26) and also the updated versions of PostgreSQL 12 and MariaDB 10.4 DBMS (with support for Libxml ++ and Maven 3.6.2 libraries).
As to X server now integrates support for PRIME technology, which on dual-GPU systems allows the base session to be displayed on the integrated GPU, and in applications selected to use a discrete graphics card.
Meanwhile in Systemd has ported support for filtering traffic in relation to services, which allows the IPAddressAllow and IPAddressDeny options to be used to define the lists of allowed and denied IP addresses and subnets, forming a simple access control system.
For x86_64 and AArch64 architectures, Vagrant Boxes are provided, a minimal set of packages to build compact virtual environments for libvirt and VirtualBox using the Vagrant toolkit.
Regarding the systems x86_64, added experimental support for "haltpoll" CPU idle driver, which decides when the CPU can go into deep power saving modes, the deeper the mode, the greater the savings, but it also takes longer to get out of the mode.
AppArmor has been updated to version 2.13 and this release adds support for profile pre-compilation and caching to speed up loading.
As for what has been removed from the distribution, in this new version graphics driver support is discontinued (UMS) user space only. SOnly drivers with KMS support remain and added HP (hpsa) and LSI (megaraid) hardware plug-ins to libstoragemgmt.
While for the part of the additions, we can find the ssupport for new hardware, including new platforms from Intel, Fujitsu A64FX, AMD EPYC, NVIDIA Tegra X1 / X2, and Raspberry Pi 4.
The U-Boot bootloader for Raspberry Pi boards (package u-boot-rpiarm64) includes experimental support for the Btrfs file system, which allows you to directly access Btrfs partitions from the bootloader and boot the kernel from them without having to start GRUB from a FAT partition.
Of the other changes that stand out of this new version:
- Removed support for PCMCIA, token ring, FDDI, myrinet, arcnet, xp (IA64 specific), and ESCON (IBM Z specific) networks from YaST.
- The YaST module for the NTP client has been moved to the systemd-timer configuration instead of cron. Moved sysctl configuration to /etc/sysctl.d/70-yast.conf file.
- Removed support for squashfs 3.x partitions (the kernel now only supports squashfs 4.0).
- Added a driver to enable EDAC (Error Detection and Correction) on AMD Zen 3 processors.
- Removed support for the legacy microcode download interface (/ dev / cpu / microcode).
- Most packages include TLS 1.3 support.
- The BIND, nginx and wireshark packets have been moved to use the GeoLite2 address-to-location base and the libmaxminddb library instead of the legacy GeoIP base, which is no longer supported.
Finally to get this new version, you should know that the distribution is free to download and use, but access to updates and patches is limited to a 60-day trial period.
