Highlights

This release includes several new features, enhancements, fixes, and maintenance/refactoring updates. Notable additions include a new Plugin API for tracing, improved support for Zephyr, and enhancements of the Docker support. Fixes address issues like path conversion on Windows and null pointer exceptions in message reporting. Maintenance efforts focus on test stabilization and dependency updates, with notable enhancements to documentation and codebase cleanliness. Additionally, enhancements and fixes are applied to the reactor-c and reactor-cpp runtime, with updates to platform APIs, memory management, and bug fixes related to tracing and enclave programs. Caution: Breaking changes are included in reactor-c's support for federated execution.
