Eclipse Ditto 3.8.0

Eclipse Ditto 3.8.0 focuses on the following areas:

• Diverting Ditto connection responses to other connections (e.g. to allow multi-protocol workflows)
• Dynamically re-configuring WoT validation settings without restarting Ditto
• Enforcing that WoT model based thing definitions are used and match a certain pattern when creating new things
• Support for OAuth2 "password" grant type for authenticating outbound HTTP connections
• Configure JWT claims to be added as information to command headers
• Added support for client certificate based authentication for Kafka and AMQP 1.0 connections
• Extend "Normalized" connection payload mapper to include deletion events
• Support silent token refresh in the Ditto UI when using SSO via OAuth2/OIDC
• Enhance conditional updates for merge thing commands to contain several conditions to dynamically decide which parts of a thing to update and which not

The following non-functional work is also included:

• Improving WoT based validation performance for merge commands
• Enhancing distributed tracing, e.g. with a span for the authentication step and by adding the error response for failed API requests
• Updating dependencies to their latest versions
• Providing additional configuration options to Helm values

The following notable fixes are included:

• Fixing nginx CORS configuration which caused Safari / iOS browsers to fail with CORS errors
• Fixing transitive resolving of Thing Models referenced with tm:ref
• Fixing sorting on array fields in Ditto search
• Fixing issues around "put-metadata" in combination with merge commands
• Fixing that certificate chains for client certificate based authentication in Ditto connection was not fully parsed
• Fixing deployment of Ditto on OpenShift
