Connection Profiles UI

New GKE Deployer

Deploy OL-Hub projects directly to Google Kubernetes Engine using the new built-in GKE deployer.

🚀 Enhancements

  • Reverse API Client Configuration When configuring a Reverse API client, users can now provide either a direct URL or an environment variable. This supports flexible deployment across multiple environments (e.g., PROD, TEST), including URIMAPs for CICS and environment variables for AS/400 COBOL.

  • Kafka Module Assets can now be generated from JSON Schema, not only JSON sample messages.

  • CICS Connector Several log messages were improved for clearer diagnostics and troubleshooting.

  • Low-Code Consumer Projects Removed application.yml from low-code consumer projects. Consumers now rely primarily on Hub configuration, simplifying maintenance and preventing conflicts between YAML and Hub settings.

🐞 Bug Fixes

  • Improved handling of multi-line input fields in 3270-style screens.
  • Flow execution no longer throws unnecessary exceptions at the end of the sequence.
  • Fixed Reverse API generation issues that previously prevented some fields from being populated at runtime.
