OpenSUSE Leap version 15.2 has been released. Leap 15 is based on SUSE Linux Enterprise, so it should combine the stability of an enterprise edition with the versatility of a community-driven operating system. In openSUSE Leap 15 we find, among other things, a new partitioner, Firewalld is used for the firewall, there is a new appearance, support for NextCloud and support for atomic updates via Kubic. The release notes for this release can be found below.
Several exciting Artificial Intelligence (AI) and Machine Learning packages have been added in Leap 15.2.
tensor flow: A framework for deep learning that can be used by data scientists, provide numerical computations and data-flow graphs. Its flexible architecture enables users to deploy computations to one or more CPUs in a desktop, server, or mobile device without rewriting code.
PyTorch: Made for both server and compute resources, this machine learning library accelerates power users’ ability to prototype a project and move it to a production deployment.
ONNX: An open format built to represent machine learning models, provides interoperability in the AI tool space. It enables AI developers to use models with a variety of frameworks, tools, runtimes, and compilers.
Grafana and Prometheus are two new maintained packages that open up new possibilities for analytical experts. Grafana provides end users the ability to create interactive visual analytics. Feature-rich data-modeling packages: Graphite, Elastic and Prometheus give openSUSE users greater latitude to construct, compute and decipher data more intelligently.
In general, software packages in the distribution grew by the hundreds. Data fusion, Machine Learning and AI aren’t all that is new in openSUSE Leap 15.2; a Real-Time Kernel for managing the timing of microprocessors to ensure time-critical events are processed as efficiently as possible is available in this release.
“The addition of a real time kernel to openSUSE Leap unlocks new possibilities,” said Gerald Pfeifer, chair of the project’s board. “Think edge computing, embedded devices, data capturing, all of which are seeing immense growth. Historically many of these have been the domain of proprietary approaches; openSUSE now opens the floodgates for developers, researchers and companies that are interested in testing real time capabilities or maybe even in contributing. Another domain open source helps open up!”
openSUSE users will have more power to develop, ship and deploy containerized applications using the newer container technologies that are being maintained in the distribution.
for the first time, Kubernetes is an official package in the release. This gives a huge boost to container orchestration capabilities, allowing users to automate deployments, scale, and manage containerized applications.
Helmet, the package manager for Kubernetes, is also added. Helm helps developers and system administrators manage complexity by defining, installing, and upgrading the most complex of Kubernetes applications.
Container Runtime Interface (CRI) using Open Container Initiative (OCI) conformant runtimes (CRI-O) is also new to this release. CRI-O is a lightweight alternative to using Docker as the runtime, which allows Kubernetes to use any OCI-compliant runtime as the container runtime for running pods or processes running on a cluster.
Even with Docker, the use of microservices will be secure thanks to more container packages arriving in this release.
Cilium helps in transparently securing network connectivity and load-balancing between application containers and services deployed using Linux container frameworks like Docker and Kubernetes. Cilium provides an efficient way to define and enforce both the network-layer and the application-layer security policies, which are based on a container/pod identity.
Leap 15.2 offers both Server and Transactional Server system roles. The Server system role uses a small set of packages that are suitable for servers with a text mode interface while the Transactional Server system role is similar to the Server role, but uses a read-only root filesystem to provide atomic, automatic updates of the system without interfering with the running system.
The openSUSE installer remains as powerful and as versatile as ever, allowing to easily tweak every single aspect of the system including the mitigation for CPU based attacks like Specter or Meltdown. The installation process presents several improvements like a more user-friendly dialog for selecting the system role, improved information about the installation progress, better compatibility with right-to-left languages like Arabic and many other small enhancements.
In Leap 15.2, it offers a more accurate detection of MS Windows partitions encrypted with BitLocker and a better management of storage devices for Raspberry Pi.The installer also makes it easy to tweak the mitigation for CPU based attacks like Specter or Meltdown.
Unattended installations with AutoYaST is greatly improved. Many aspects are polished at all levels. More configuration options are added and the possible errors in the user’s profile and the installation process are now handled and reported in a more sensible and informative way.
Improvements to YaST – The most complete configuration tool for Linux
The YaST Partitioner remains the most powerful tool to configure all kinds of storage technologies in Linux, both during installation of the system or at any later point. This release incorporates the possibility of creating and managing a Btrfs file-system that expands over several devices, and the release allows for the use of more advanced encryption technologies.
Leap 15.2 is the first openSUSE release to introduce a gradual change that splits system’s configuration between /usr/etc and /etc directories. YaST supports this new structure in all the affected modules, offering to system administrators a central point to inspect the configuration that will help them during the transition and beyond.
Leap can be executed on top of the Windows Subsystem for Linux (WSL), delivering the power of openSUSE to the Windows world. The YaST version in Leap 15.2 improves the compatibility with that platform, specially when executing YaST Firstboot in order to perform all the needed initial adjustments.
While the desktop environments in this release will be new, the focus remains on more conservative fixed release. The Long-Term-Support version of KDEs Plasma 5.18 is available in Leap 15.2. The newer LTS has a significant amount of polish and new features. Notifications are clearer, settings are streamlined and the overall look is more attractive. GNOME 3.34 updates from the previous 3.26 version that was available in Leap 15.1. The new GNOME provides a considerable amount of visual refreshes for a number of applications. More data sources in Sysprof makes performance profiling of an application even easier and there are multiple improvements to Builder including an integrated D-Bus inspector. Xfce has a minor update to version 4.14 after four plus years of development; the new version produced a slew of updates and features, including enhancements for the window manager, file manager, application finder and power management.
Cloud Images, Hardware and Architectures
linode cloud images of Leap are available today and ready for all infrastructure needs. Cloud hosting services will offer images of Leap 15.2 in the coming weeks like Amazon Web Services, Azure, Google Compute Engine and OpenStack. Leap 15 is continually optimized for cloud usage scenarios as a host and virtualization guest.
Leap deployment scenarios include physical, virtual, host and guest, and cloud. Ports to other architectures like ARM64 and POWER are expected in the coming weeks.
Compilers, scripting languages, system configuration tools and graphical user interfaces have all been improved.
GNU Compiler Collection 7 through 9 are available in this newer Leap minor version along with an updated version of the 3D Graphics package Mesa to support the use of the professional grade operating system. Leap 15.2 has the same 234 version of systemd used in Leap 15.0 and 15.1.
New graphics hardware support has been backported for the release of Leap 15.2 and Linux Kernel 5.3 will be used for the release. Kernel features automatically become available in Leap since the distribution shares the same kernel as SUSE Linux Enterprise (SLE).
openSUSE Leap 15.2 is a distribution with community packages built on top of core sources of SLE 15 Service Package 2. The shared common core and alignment with SLE makes migrations to SUSE’s enterprise product easy for professional who want to extend the life cycle of their maintenance and security past the life cycle of Leap. Migrating from the community version of Leap to SUSE Linux Enterprise is an available option for those who desire to migrate. The migration from openSUSE Leap server installations to SUSE Linux Enterprise is easy for system integrators developing on Leap code who may decide to move to an enterprise version for SLAs, certification, mass deployment, or extended Long Term Support.
This Leap release increases the capabilities of health services. The award-winning health and hospital management system GNU Health comes in version 3.6.4. It has an updated GUI and is prepared for COVID-19 pandemic tracking, including updated ICD-10 codes and improved laboratory functions. GNU Health can directly interface with Orthanc, the free PACS Server, which is newly shipped in this release. Developers of the health and medical fields have several open-source tools with openSUSE Leap that can be used for creating powerful User Interfaces (UI) and User Experiences (UX) for medical devices. Healthcare device developers can be confident in the use and performance of Leap and rely on the system supporting newer and older hardware.
System administrators will have the most up-to-date tools for configuration management. Salt 3000 has arrived in Leap; the new Salt version removes the date versioning and provides new functions to chroot: apply, sls, and highstate. It also updates slot syntax to support parsing dictionary responses and to append text. Ansible is also available for sysadmins. Ansible works over SSH and does not require any software or daemons to be installed on remote nodes.
Groupware and File Hosting
File sharing and cloud services include software such as NextCloud and even the groupware application suite Kopano (formerly known as Zarafa) is part of the official Leap 15.2 repositories.
Like prior versions, System Administrators and small businesses can use Leap for hosting web and mail servers or for network management with DHCP, DNS, NTP, Samba, NFS, LDAP, and hundreds of other services.
Life Cycle of Leap
Minor versions of the Leap 15 series have about an 18-month life cycle; minor releases come roughly once a year. Users of openSUSE Leap 15.1, which was released in May of 2019, should upgrade to Leap 15.2 within the next 6 months. The first release of Leap 15 was released two years ago. Download Leap 15.2
