This release includes major improvements for Kafka protocol handling, enhanced dashboard usability, and better HTTP module features.

Kafka Protocol Improvements

• Flexible versions:
  • Fixed flexible response handling for multiple APIs (FindCoordinator, JoinGroup, SyncGroup, ListGroup, Heartbeat, CreateTopics).

• Fixed applying references with sibling attributes in JSON Schema.
• Fixed null validation errors overriding other errors for nullable types ([object, null]).
• Fixed conversion of nullable OpenAPI schemas where nullable: true without an explicit type incorrectly produced type: "null".

JavaScript HTTP Module

• Added timeout option to JavaScript HTTP requests (supports numeric or duration string, e.g. "5m").

Dashboard

• Added client IP address to HTTP request view.
• Added filtering feature to the HTTP requests list.
• Improved responsiveness and alignment in the HTTP requests table.
