Server

Pagure Git hosting forge server

Introduced in Leap 15.1, the Pagure Git hosting forge server software has been updated for Leap 15.3. Like with Leap 15.1 and Leap 15.2, an openSUSE-flavored theme is provided as the default.

Pagure provides an easy, customizable, lightweight solution to setting up your own full-featured Git repository server. It is similar to other popular Git-based forges, allowing developers and contributors to share and collaborate on code and content. However, it also has some unique features not found in any other Git forge providing the basis for decentralized, federated software code hosting and development.

For Leap 15.3, Pagure has been updated to version 5.13.2. Some highlights of the new version:

• Per-branch write access ACL with "collaborator" role in projects
• New API endpoints for project administration
• Support for mail servers using STARTTLS has been added for sending notification emails
• Support for configuring preferred default main branch for new projects instance-wide
• Add pagination to various API endpoints
• Migrate PR flags to commit flags, the PR flags API endpoint is deprecated now
• Support for updating the target branch when editing a PR

Please read "/usr/share/doc/packages/pagure/UPGRADING.rst" for details on how to handle upgrading from 5.5 or 5.10.0 to 5.13.2.

GNU Health

GNU Health is a set of modules for the Tryton server. The GNU Health HMIS provides the following functionality:

• Hospital Management Information System (HMIS)
• Electronic Medical Record (EMR)
• Health Information System (HIS)
• Laboratory Information System (LIS)

It is prepared for COVID-19 pandemic tracking, including updated ICD-10 codes and improved laboratory functions. Take advantage of the Dentistry Package. Interface directly with Orthanc, the free PACS Server.

Desktop Environments

Xfce

Xfce 4.16 introduces new major features. There is a new visual identity in this release of Xfce. With new icons and palette, Xfce shines a little more out of the box. The Settings Manager received a visual refresh of its filter box, which can now be hidden permanently. The search capabilities of the filter box were improved by searching the descriptive 'Comments' part of each dialog's launcher (aka .desktop) file. The settings dialog of the power manager was cleaned up and shows either 'on battery' or 'plugged in' settings as opposed to both in a huge table.

With default applications, a new dialog represents a merger between the previously available 'Mime Settings' and the 'Preferred Applications' dialogs. Consolidating both in one place means users have an easier time setting default applications to handle certain file types. To better support high-density displays, which come in various sizes and densities, 4.16 adds fractional scaling based on the RandR extension of X11; the preferred mode of a display is now marked with an asterisk and aspect ratios are shown along display resolutions.

The copy and move dialogs users can now easily pause the respective file operation in Thunar. Support for queued file transfer, remembering view settings per folder and support for transparency in Gtk themes was added. The panel received quite a few noteworthy updates, an animation for autohide and intellihide, a new 'Status Tray' plugin that combines both legacy Systray item support with modern StatusNotifier item support, dark mode support, launchers showing additional actions on right-click, window buttons offering to 'Launch a new instance...' and much more.

KDE

Plasma

Plasma 5.18 LTS is the third long-term support release from the KDE Plasma team. Leap 15.3 includes this new LTS version. In Plasma 5.18 you will find neat features that make notifications clearer, settings more streamlined and the overall look more attractive. Plasma 5.18 is easier and more fun to use, while at the same time allowing you to be more productive when it is time to work.

If you are thinking of updating or migrating your school, company or organization to Plasma, this version is your best bet, as you get the most stable version of Plasma *and* all the new features too.

Plasma 5.18 is even more user-friendly as we have added more features that let you work, play and express yourself better. Take the new Emoji Selector: it is literally always just two keystrokes away. Hold down the Meta (Windows) key and press the period (.) and it will pop up. Click on the icon that best represents your feelings and you can paste the emoji into your email, social media post, text message or even your terminal.

Continuing with improvements to the overall look, Plasma 5.18 comes with better support for GTK applications using client-side decorations. These applications now show proper shadows and the resize areas for them. GTK apps now also automatically inherit Plasma's settings for fonts, icons, mouse cursors and more. Plasma now starts significantly faster and start-up scripts have been converted from bash to C++ and now run asynchronously. There is also much better support for public WiFi logins.

To help relax your eyesight, there's a new system tray widget that lets you toggle the Night Color feature. You can also configure keyboard shortcuts to turn Night Color and Do Not Disturb modes on or off.

System Settings

There are quite a few new things in Plasma 5.18's System Settings. First and foremost is the optional User Feedback settings. These are disabled by default to protect your privacy. The System Settings Virtual Desktops page has been rewritten for Wayland support and there is a new panel for managing and configuring Thunderbolt devices.

Frameworks

KDE Frameworks are over 70 addon libraries. Frameworks 5.76.0 is expected for the Gold Master. The newer KDE Frameworks had made changes to several packages including Baloo, Breeze Icons, KAuth, KActivities, KConfig, KIO, Kirigami, KWidgetsAddons, KWayland, Oxygen Icons and more.

Applications

KDE Applications were updated to version 20.04.2. The version includes improvements to the music player Elisa, search tags for the file manager Dolphin and faster editing with KDE’s advanced video-editing application Kdenlive.

GNOME

Leap 15.3 offers GNOME 3.34 (named Thessaloniki), which comes with a large number of new features, bug fixes, and better performance.

Folder Management

It is possible to create, rename, and delete folders using Drag n’ Drop actions in the application overview. This makes organizing applications much easier and keeps the application overview clutter-free. The overview visual style was refined as well, including the search entry field, the login password field, and the overview window highlight border.

Accessibility

The old accessibility mechanisms can not work on Wayland (as Wayland clients have no access to the global coordinates and cannot manipulate the pointer). 3.34 migrates Locate Pointer, Click Assist, and other features to gnome-shell/mutter, which works in X11 as well.

Applications

Improvements to core GNOME applications include new icons, sandboxed browsing in Web, gapless playback in Music, support for bidirectional text in the Terminal, more featured applications in Software, and more.

You may check out the full release notes for technical details.

General Improvements

Linux kernel

Leap 15.3 will use the 5.3.18 Linux Kernel. The kernel in Leap is the same kernel used in SUSE Linux Enterprise 15 Service Pack 3. This kernel version is maintained by SUSE. This Linux 5.3 kernel introduces support for AMD Navi GPUs, and new IPv4 addresses. RISC-V code improvements are made with this updated kernel and it's compatible with Intel Speed Select used in Intel Xeon servers.

Hardware Support

Leap 15.3 works with x86_64, aarch64, PowerPC (ppc64le) and s390x. Deployment scenarios can be run for physical, virtual, host and guest, and cloud.

systemd

Leap 15.3 includes systemd version 246.10-1.10, which includes backport fixes and updates. This System and Service Manager is a suite of basic building blocks for a Linux system that runs as PID 1 and starts the rest of the system.

systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. systemd supports SysV and LSB init scripts and works as a replacement for sysvinit.

Other parts include a logging daemon, utilities to control basic system configuration like the hostname, date, locale, maintain a list of logged-in users and running containers and virtual machines, system accounts, runtime directories and settings, and daemons to manage simple network configuration, network time synchronization, log forwarding, and name resolution.

Mesa

Mesa 20.2.4 is a bug fix release and implements the OpenGL 4.6 API, but the version reported by glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. Some drivers don’t support all the features required in OpenGL 4.6. OpenGL 4.6 is only available if requested at context creation. Compatibility contexts may report a lower version depending on each driver.

Mesa 20.2.4 implements the Vulkan 1.2 API, but the version reported by the apiVersion property of the VkPhysicalDeviceProperties struct depends on the particular driver being used.

Security, Networking and Privacy

AppArmor

The AppArmor Parser is a userlevel program that is used to load in program profiles to the AppArmor Security kernel module. AppArmor 2.13.6 is a maintenance release of the user space components of the AppArmor security project. The kernel portion of the project is maintained and pushed separately. This version of the userspace should work with all kernel versions from 2.6.15 and later.

dehydrated / letsencrypt

Dehydrated is a client for signing certificates with an ACME-server (currently only provided by Let’s Encrypt) implemented as a relatively simple bash-script.

It uses the openssl utility for everything related to actually handling keys and certificates, so you need to have that installed.

Other dependencies are: cURL, sed, grep, mktemp (all found on almost any system, cURL being the only exception)

Current features:

• Signing of a list of domains
• Signing of a CSR
• Renewal if a certificate is about to expire or SAN (subdomains) changed
• Certificate revocation

OnionShare

OnionShare lets the user share files securely and anonymously. It works by starting a web server, making it accessible as a Tor Onion Service, and generating an unguessable URL to access and download the files. It does not require setting up a separate server or using a third party file-sharing service. Files are hosted on the machine the program is run on. The receiving user just needs to open the URL in Tor Browser to download the file. Leap 15.3 has version 2.2.

Tor

Anonymizing overlay network for TCP (The onion router)

Tor is a connection-based low-latency anonymous communication system. This package provides the "tor" program, which serves as both a client and a relay node. Scripts will automatically create a "tor" user and a "tor" group, and set tor up to run as a daemon when the system is rebooted. Applications connect to the local Tor proxy using the SOCKS protocol. The tor client chooses a path through a set of relays, in which each relay knows its predecessor and successor, but no others. Traffic flowing down the circuit is unwrapped by a symmetric key at each relay, which reveals the downstream relay. Warnings: Tor does no protocol cleaning. That means there is a danger that application protocols and associated programs can be induced to reveal information about the initiator. Tor depends on Privoxy or similar protocol cleaners to solve this problem. This is alpha code, and is even more likely than released code to have anonymity-spoiling bugs. The present network is small -- this further reduces the strength of the anonymity provided. Tor is not presently suitable for high-stakes anonymity.

Package Manager

DNF package manager

DNF is a next-generation dependency resolver and high-level package management tool that traces its ancestry to two projects: YUM (Yellowdog Updater, Modified) and libsolv. DNF was forked from YUM several years ago in order to rewrite it to use libsolv and to massively restructure the codebase so that a sane API would be available for both extending DNF (via plugins and hooks) and building applications on top of it (such as graphical frontends and system lifecycle automation frameworks).

DNF provides the following over YUM: a maintained and documented Python API, enhanced problem reporting, advanced tracking of weak dependencies, support for rich dependencies, and more detailed transaction information while performing actions.

The DNF Python API is stable and supported, while the underlying libdnf and hawkey APIs (both C/C++ and Python) are unstable, and will likely change in future releases.

In addition, a lightweight C implementation of DNF called "Micro DNF" is included. It is designed to be used for doing simple package management actions when you don't need full-blown DNF and you want the tiniest useful environments possible. This is useful for the case of minimal containers and appliances.

Finally, an experimental alternative PackageKit backend to use DNF is also available.

Some highlights:

• Support for "sticky vendors" that is enabled by default. This can be disabled by setting "allow_vendor_change=True" in /etc/dnf/dnf.conf
• Experimental support for transactional updates with Micro DNF and PackageKit. This requires creating images with this functionality, which can be done with the KIWI image builder tool.
• Experimental support for offline updates and upgrades using DNF is available.
• Experimental "opensuse/leap-dnf" and "opensuse/leap-microdnf" base containers are now available.

DNF is currently not configured with openSUSE repositories for software management by default. However, the "libdnf-repo-config-zypp" package enables DNF to use the repository configuration that is used by YaST and the Zypper package manager. Alternatively, the "rpm-repos-openSUSE-Leap" package provides stable repository configuration independent of Zypper/YaST for DNF to use.

Finally, upgrading from Leap to Tumbleweed is now supported with DNF by installing "rpm-repos-openSUSE-Tumbleweed" and using "dnf --refresh offline-distrosync". If you have either "libdnf-repo-config-zypp" or "rpm-repos-openSUSE-Leap" already installed, "dnf install --allowerasing rpm-repos-openSUSE-Tumbleweed" will swap to that package for upgrading.

Currently, GCompris offers in excess of 100 activities. New activities can be added, and an activity can implement its own game scheme. This version is a rewrite of GCompris using the QtQuick technology.

SuperTuxKart

SuperTuxKart is a Free 3d kart racing game. The focus of the game is more to be fun than it is to be realistic. You can play with up to 4 friends on one PC, racing against each other or just try to beat the computer. See the great lighthouse or drive through the sand and visit the pyramids. Race underground or in space, watching the stars passing by. Have some rest under the palms on the beach (watching the other karts overtaking you :) ). But don't eat the bananas! Watch for bowling balls, plungers, bubble gum and cakes thrown by opponents. You can do a single race against other karts, compete in one of several Grand Prix, try to beat the high score in time trials on your own, play battle mode against your friends, and more!

Programing Languages

Go

The latest Go release, version 1.15, is available with openSUSE Leap 15.3. Most of the changes are in the implementation of the toolchain, runtime, and libraries. The release maintains the Go 1 promise of compatibility. The Golang team expects almost all Go programs to continue to compile and run as before.

Go 1.15 includes substantial improvements to the linker, improves allocation for small objects at high core counts, and deprecates X.509 CommonName. GOPROXY now supports skipping proxies that return errors and a new embedded tzdata package has been added.

Go 1.15 includes a new package, time/tzdata, that permits embedding the timezone database into a program. Importing this package (as import _ "time/tzdata") permits the program to find timezone information even if the timezone database is not available on the local system. You can also embed the timezone database by building with -tags timetzdata. Either approach increases the size of the program by about 800 KB.

Perl

Perl 5.26.1 continues to flourish thanks to a vibrant community of users and developers. The release has several security fixes that have been backported, and the 5.26.1 release had several bugfixes. There are several other Perl packages in Leap 15.3 to include Perl Mojolicious 8.66 and PerlMagick 7.0.7.34.

PHP 7

PHP is a popular general-purpose scripting language that is especially suited to web development. It's fast, flexible and pragmatic. PHP powers everything from blogs to the most popular websites in the world. PHP 7.4.6 significantly boosts performance and improves code readability. The most interesting features and changes are the benefit of Spread Operator in an array expression and the introduction of the shorter and clearer syntax of the arrow functions.

Python

This release of Leap 15.3 includes Python 3.6.12, just like Leap 15.2. The release is a modern interpreted, object-oriented programming language, often compared to Tcl, Perl, Scheme, or Java. You can find an overview of Python in the documentation and tutorials included in the python3-doc package. The package supplies rich command line features provided by readline, and sqlite3 support for the interpreter core, thus forming a so called "extended" runtime. Installing "python3" is sufficient for the vast majority of usecases. In addition, recommended packages provide UI toolkit support (python3-curses, python3-tk), legacy UNIX database bindings (python3-dbm), and the IDLE development environment (python3-idle).

New syntax features:

PEP 498, formatted string literals.
PEP 515, underscores in numeric literals.
PEP 526, syntax for variable annotations.
PEP 525, asynchronous generators.
PEP 530: asynchronous comprehensions.

Security improvements:

The new secrets module has been added to simplify the generation of cryptographically strong pseudo-random numbers suitable for managing secrets such as account authentication, tokens, and similar.
On Linux, os.urandom() now blocks until the system urandom entropy pool is initialized to increase the security. See the PEP 524 for the rationale.
The hashlib and ssl modules now support OpenSSL 1.1.0.
The default settings and feature set of the ssl module have been improved.
The hashlib module received support for the BLAKE2, SHA-3 and SHAKE hash algorithms and the scrypt() key derivation function.

Ruby

Ruby 2.5 has many new features and performance improvements. The notable changes are as follows:

Support branch coverage and method coverage measurement. The branch coverage indicates which branches are executed and which are not. The method coverage indicates which methods are invoked and which are not. By running a test suite with these new features, you will know which branches and methods are executed, and evaluate total coverage of the test suite more strictly.
One of our most loved libraries, pp.rb, is now automatically loaded. You no longer have to write require "pp".
Hash#slice [Feature #8499] and Hash#transform_keys [Feature #13583]
Struct.new can create classes that accept keyword arguments. [Feature #11925]
Block passing by a block parameter (e.g. def foo(&b); bar(&b); end) is about 3 times faster than Ruby 2.4 by “Lazy Proc allocation” technique. [Feature #14045]
Mutex is rewritten to be smaller and faster. [Feature #13517]

Rust

Rust is a programming language that is empowering everyone to build reliable and efficient software. The version in Leap 15.3 is Rust 1.43.1. Rust has burst onto the scene as a popular systems programming language. Rust 1.43.1 addresses two regressions introduced in the 1.43.0 stable release, and updates the OpenSSL version used by Cargo. As a systems programming language, it is focused on three goals: safety, speed, and concurrency. Rust maintains these goals without having a garbage collector, making it a useful language for a number of use cases. It improves on current languages targeting this space by having a number of compile-time safety checks that produce no runtime overhead, while eliminating all data races. Rust also aims to achieve "zero-cost abstractions", even though some of these abstractions feel like those of a high-level language. Even then, Rust still allows precise control like a low-level language would.
