v0.2.14

Module Name: baselibs
Release Tag: v0.2.14
Origin Release Tag: v0.2.13
Release Commit Hash: 09be72c
Release Date: 2026-09-29

Overview

The baselibs module provides a selection of basic C++ utility libraries for common use in the S-CORE project.

Disclaimer

This release is not intended for production use, as it does not include a safety argumentation or a completed safety assessment.
The work products compiled in the safety package are created with care according to the S-CORE process (https://eclipse-score.github.io/process_description/main/index.html). However, as a non-profit, open-source organization, the project cannot assume any liability for its content.

Notable Changes

Breaking changes & deprecations

• Deprecated //src Bazel aliases and the string and atomic shims in //score/memory have been removed. Consumers must use the replacement targets. #598
• The score::flatbuffers::LoadBuffer overload that accepted std::pmr::vector<uint8_t> now accepts score::cpp::pmr::vector<uint8_t> instead. Callers using the former type must update their containers. #603
• The v0.2.13 change to score::os::StatBuffer user and group IDs has been reverted because it caused other issues: st_uid and st_gid are again signed std::int64_t. The unsigned-ID fix described in the previous release notes is not present in this release. #630

New features

• NonRelocatableVector now provides pop_back(), clear(), and empty(). clear() destroys the elements without changing capacity. #599
• Linux applications can use the new, mockable score::os::Syslog wrapper for openlog, syslog, and closelog. #502
• score/json offers vaJson as an alternative serialization backend, selected with --//score/json:writer_library=vajson. The existing backend remains the default; vaJson emits compact JSON rather than the default backend's indented output. #520
• FutureCPP's score::cpp::inplace_vector range constructor now supports single-pass input iterators, and score::cpp::optional<T> can be constructed from std::optional<T>. #613

Compatibility

The following platforms are supported using the bazel_cpp_toolchains (https://github.com/eclipse-score/bazel_cpp_toolchains):

• x86_64-unknown-linux-gnu
• aarch64-unknown-linux-gnu
• x86_64-unknown-nto-qnx800
• aarch64-unknown-nto-qnx800

Performed Verification

• Build on all supported platforms
• Unit test execution on all supported platforms (some test failures are expected on AArch64 and QNX targets).
• Address and undefined behavior sanitized unit test execution
• Leak sanitized unit test execution

Upgrade Instructions

Backward compatibility with the previous release is not guaranteed.
