🚀 Developer Experience — Faster, Smarter, Guided

Conversational Multi-Turn Integration Development

This release adds multi-turn conversational integration development with AI.

Supported workflow:

1. Provide requirements in natural language
2. Receive an AI-generated integration plan
3. Refine integration through multi-turn conversations
4. Generate full end-to-end integration artifacts
5. Continue refining within the visual design environment

Scope of assistance includes planning, configuration, validation, and refinement.

🤖 GenAI App Development — With Production-Grade Controls

LLM Evaluation Framework

This release introduces an evaluation framework for validating GenAI behavior before production rollout.

Capabilities include:

• Trace-Based Evaluation – Use real execution traces as evaluation inputs
• Custom Evaluation Rules – Define assertions and behavioral tests
• LLM-as-a-Judge Support – Evaluate output quality and reasoning correctness
• Reusable Dataset Creation – Build datasets from collected traces

Agent Execution Visualizer (Development-Time Transparency)

The Agent Execution Visualizer provides development-time visibility into:

• Reasoning steps
• Tool invocation sequences
• Decision loops
• Intermediate outputs

This helps with debugging agent behavior and validating tool-use flows.

Observability for GenAI Applications

WSO2 Integrator now provides two layers of visibility:

Operational Observability

• Latency monitoring
• Token usage tracking
• Model call metrics
• Failures and retry insights
• Cost-awareness signals

AI Execution Insights

• Prompt tracing
• Response inspection
• Tool interaction tracking
• Reasoning flow visibility

🔗 Connectivity for Modern Architectures

Native Solace Support

WSO2 Integrator now includes first-class support for Solace PubSub+ via a dedicated connector.

Capabilities include:

• Connect to Solace Topics and Queues: Seamlessly publish and subscribe to events across the Solace Event Mesh.
• Leverage Advanced Messaging Patterns: Utilize features such as guaranteed messaging, message persistence, and fine-grained access control.

---

📁 File Integration Built for Distributed Scaling

Conflict-Free Multi-Node File Processing

A new coordination model ensures that only one processing node handles a file at any given time in clustered deployments.

Benefits include:

• Elimination of duplicate reads
• Prevention of race conditions
• Automatic failover and seamless handoff
• Exactly-once processing guarantees

This improves correctness for distributed file-based integration flows.

---

File Handling Stability & Usability Improvements

• Enhanced fault tolerance for batch processing
• Sophisticated retry mechanisms
• Configurable backoff strategies (including exponential backoff)
• Improved distinction between transient and fatal errors

---

Looking Ahead

Future updates will continue to build on these areas with additional integration tooling, AI capabilities, and operational improvements.
