Eclipse Ditto™ 2.3.0

The main improvements and additions of Ditto 2.3.0 are:

• HTTP API for “live” commands
• Smart channel strategy for live/twin read access
• Configurable allowing creation of entities (policies/things) based on namespace and authenticated subjects
• Allow using * as a placeholder for the feature id in selected fields

The following notable fixes are included:

• Fix potential concurrent modification errors when using JavaScript payload mapping and global variables
• Fix reconnect backoff for Kafka connections with authentication failures
• Fix caching of JWTs in HTTP push connections
• Fix potentially unreachable client actors in connections with clientCount > 1
• Fix search inconsistencies for very active things during shard relocation (e.g. on rolling updates)
• Fix that a Kafka connection with only targets remains “open” even if Kafka broker is not available
• Allow usage of absolute domain paths ending with a “.” as Kafka bootstrap servers
• Ensure that Ditto pub/sub state is eventually consistent with a guaranteed upper time limit

The following non-functional work is also included:

• Update of several used dependencies
