Migration Guides: Humble to Jazzy

This list summarizes important changes between Humble (previous) and Jazzy (current) releases, where changes to user code might be necessary.

Note

This list was created in June 2025 (tag 3.6.0), earlier changes may not be included.

RealtimeBox

• RealtimeBox is deprecated. Update your code to use realtime_thread_safe_box.hpp header, and class name RealtimeThreadSafeBox instead. (#318, #342).

• RealtimePublisher is updated with a new try_publish API. Update your code with a local message variable and call try_publish with that variable. The old API is deprecated and will be removed in a future release. (#323).
