Generic Document
Platform Name: S-CORE
Release Tag: v0.6.0
Origin Release Tag: v0.5.0-beta
Release Date: 2026-02-23

Overview#

This is the third milestone build of the Eclipse S-CORE platform (v0.6.0). It brings together the initial set of core modules, reference integrations, and supporting infrastructure needed to build and run example applications such as the scrample demo on multiple target images. The software architecture and implemented modules are illustrated in the diagram below.

This release of Eclipse S-CORE is an early beta version intended solely for experimentation, test driving project processes, gaining experience in release creation and soliciting feedback. Please be aware, that features may be incomplete, the software may exhibit instability or unexpected behavior, and breaking changes and alterations in scope are likely as development progresses.

Architecture overview

Highlights#

Eclipse S-CORE book#

The Eclipse S-CORE book is a “how-to” guide for users getting started with the project or who want to contribute new modules.

Improvements#

S-CORE Platform#

Integrated Software Modules#

Baselibs#

Selection of basic C++ utility libraries for common use in the S-CORE project

Baselibs Rust#

Selection of basic Rust utility libraries for common use in the S-CORE project

Improvements

  • score_log - logging frontend for S-CORE

  • containers- common containers with different allocation and layout techniques including ABI compatible versions for inter-process communication

  • sync - std::sync extensions utilities

Communication#

Zero-copy, shared-memory based inter-process communication for minimal-latency intra-ECU messaging.

Improvements

  • Enabled various code quality tools

  • Extension of the Rust API (expect further extensive work on this API)

  • Support explicit setting of application id in configuration (with fallback to PID)

Persistency#

Ensures long-term storage and retrieval of data and provides a reliable mechanism for preserving application state and data integrity over time.

Improvements

  • New backend API for Rust

  • Testing improvements, including: - Additional C++ CIT tests, code quality improvements, tests logging.

  • Tooling improvements, including: - Improved formatting, Rust linting.

  • Aligned snapshot count behavior between C++ and Rust implementations.

  • Adapted Ferrocene toolchain for Rust.

  • Updated utilized toolchains, updated S-CORE dependencies.

Logging#

Improvements

The Eclipse S-CORE Logging module provides a logging framework for automotive embedded systems, featuring remote DLT (Diagnostic Log and Trace) capabilities with lock-free communication between applications and the datarouter daemon.

Orchestrator#

Orchestrator module provides a framework for defining and executing complex workflows and task sequences in a coordinated manner.

Improvements

  • Adapted toolchain to ferrocene for Rust

  • Support qnx-x86_64

  • Examples now run in reference integration repository images

Kyron#

Kyron is a customizable, high-performance async/await runtime designed for advanced concurrent programming with focus on functional safety. It allows fine-grained control over scheduling, thread management, and workload isolation through configurable execution engines.

Improvements

  • Adapted toolchain to ferrocene for Rust

  • Support qnx-x86_64

  • Integrated rust coverage reporting

  • Improved up to 8% runtime time with task scheduler fixes

  • Examples now run in reference integration repository images

Bugfix

  • Minor bugfixes listed in github

Known issues

  • Ongoing fixing of safety wakes here

Lifecycle & Health Management#

Lifecycle module provides a Launch Manager for process lifecycle management as well as a Health Monitoring library to support supervision of process behavior.

Improvements

  • Health Monitoring library for applications with Rust and C++ API - Deadline Monitoring support

  • Initial version of Launch Manager with mw::lifecycle API - The previously separate daemon processes launch_manager and health_monitor are now merged into a single launch_manager daemon process

  • Working integration of Launch Manager and Health Monitoring library

Reference integration#

Central integration of Eclipse S-CORE modules

Improvements - Unify handling of images in repository - Execute all images build and tests in CI - Execute UT, Coverage in CI and produce documentation with results - Provide ./score_starter helper program to allow easily run given image without hassle - Provide interactive example selection menu on target image so user can choose examples to run and see the results - Remove separate bazel modules and use single bazel module with always aligned dependencies

Reference QNX image#

  • No changes compared to the previous software version.

Reference Red Hat AutoSD Linux image (Experimental)#

Improvements

  • Remove unused packages to reduce image size

  • Move AutoSD images to use Bootc (image mode)

  • Integrate AutoSD’s Bazel toolchain to build reference integration showcases

Reference Elektrobit corbos Linux for Safety Applications Linux image (Experimental)#

  • Updates to follow the latest integration structure and dependencies.

  • No functional changes compared to the previous software version.

Associated Infrastructure Modules#

process_description#

Provides a process model establishing organizational rules for developing open source software in the automotive domain, suitable for safety and security contexts.
