Release 5.2.0

Highlights

Runtime 5.2 is a major release focused on multi-provider AI agent support, AI agent infrastructure overhaul, and a broad sweep of internal quality improvements across the data layer, observability stack, and Kubernetes/Helm configuration.

New AI features & enhancements

• The AI Agent Hub now supports multiple LLM providers beyond OpenAI: Anthropic, Google (including VertexAI authentication), Azure OpenAI (including ClientSecret authentication), and Cerebras are now also supported.

• AI agent conversations and messages are no longer stored in the central runtime database but in each application's own database, making sure they are always backed-up and migrated together with the application data.

• A new AI agent conversation field type has been added, with expression support and new functions: DateCreated(), DateModified(), GetAgent(), and HasContent().

• Reasoning and thinking mode can now be enabled for AI agents.

• Improved model controls: max output tokens, reasoning effort, temperature, topP, verbosity, etc.

• AI agents can now receive image and file attachments. Supported file types are defined per model via SupportedFileTypes in the model specification.

• Support for native hosted tools of the LLM provider (file search, web search, code interpreter).

• Structured input and output messages with the "Invoke AI agent" flowchart node.

• AI agent chatbox improvements:

  • Read-only mode

  • Better loading indicator

  • Option to view internal information such as initial instructions, reasoning and function calling

Other improvements

• ToConcept(localName, rootConcept) overload: A new overload of the ToConcept() function has been added, accepting both a local name and a root concept.

• GKE support: Kubernetes service account annotations and deployment labels for GKE have been added.

• Request timeout: Application.RequestTimeout is now used when creating the nginx configuration files.

• Application activity log metrics are now emitted.

• The public __wem/checks/operational endpoint now returns only a status string.
