For details on the features, see https://eclipse-score.github.io/score/main/features/baselibs/index.html

Improvements

• score/result: Added Rust FFI bindings for score::Result and associated types (score::details::expected, score::Error, score::ErrorDomain, std::string_view). Results can be transferred across FFI boundaries and converted to Rust
  std::result::Result. Includes ABI detection for runtime compatibility checking and a CXX macro for importing typedefs on the C++ side.
• score/mw/log: Added RegistryAwareRecorderFactory with a plugin architecture for backend selection. Added backend plugin registrants for file, remote DLT, and QNX slog. Added CreateRecorderFromLogMode. Introduced
  mw/log:minimal as a stub empty backend target. Refactored composite recorder to internal detail namespace.
• score/filesystem: Refactored AtomicUpdate internals. Temporary files are now cleaned up on all failure paths (destructor, Close() failure, file-stream creation failure). Added fsync on the parent directory after rename.
• score/memory/shared: Applied MeyerSingleton to initialize static singletons. Added mutex locking when opening shared memory objects. Added feature-flag visibility support.
• score/result: Switched ResultBlank from void* to void. Deprecated StringLiteral alias. Removed transitive dependency on score::cpp::optional.
• score/os: Migrated internal usage to ScopeExit utility.
• Build System / CI: Marked unneeded MODULE.bazel dependencies as dev-only. Added explicit amp_assert.h includes across filesystem, concurrency, json, libos, and platform/aas. Updated QNX build workflow to use latest
  version from cicd-workflows. Increased test timeouts for AArch64 builds.

Bug Fixes

• score/filesystem: Fixed lcov coverage exclusion markers (LCOV_EXCL_START/STOP). Fixed multiple QNX8 Coverity warnings in lib/filesystem and lib/json. Removed QNX8-specific #ifdef that was no longer needed. Reverted and
  re-applied fsync-parent-dir change to avoid a regression on non-regular files.
• score/mw/log: Fixed missing Bazel dependency. Removed redundant recorder_config.h. Tagged QNX slog backend target as manual to prevent unintended build inclusion.
• score/result: Fixed missing and incorrect copyright headers.
• score/os: Fixed mman unit tests after ES2 integration changes.
• score/memory/shared: Fixed incorrect feature-flag visibility on lib/memory/shared targets.

Compatibility

The following platforms are supported using the bazel_cpp_toolchains:

• x86_64-unknown-linux-gnu
