Contents (#625)

IMPORTANT: There is 1 breaking change.

Enhancements

• Allow setting of maximum number of workers for parallel questions in Child.ask_multiple
• Pull up to 50 messages from answer subscriptions at once instead of 1
• Allow skipping of any missing message after a 10s delay in OrderedMessageHandler
• Suppress name/namespace override warning if the value is the same in the environment and service configuration file
• Speed up event validation by caching service communication JSON schema
• 💥 BREAKING CHANGE: Extract SRUID for child logs context from subscription in message handler

Fixes

• Exit early from message pulling if heartbeat check fails
• Make Manifest.update_dataset_paths method thread-safe

Refactoring

• Factor out multiple checks of package version in message handler

Testing

• Improve message handling tests by not mocking _pull_and_enqueue_available_messages method and removing MockMessagePuller

---

Upgrade instructions

💥 Extract SRUID for child logs from subscription in message handler

This removes the service_name argument from Service.wait_for_answer. If you were using this argument, simply remove it; logs from children shown in a parent will now have the full and correct SRUID automatically.
