Together, these updates empower teams to innovate faster, govern integrations effectively, and operate reliably across the enterprise.

What’s new?

The November 2025 release further enhances WSO2 Integrator’s AI-driven integration and GenAI application development capabilities, enabling enterprises to not only connect their systems faster, but also build more intelligent apps and autonomous agents that understand, reason, and act on business context.

Here’s what makes this release truly transformative:

  • Build GenAI-powered apps
    Create applications that don’t just integrate data, but use it intelligently. With enhanced built-in Retrieval-Augmented Generation (RAG) features, multi-modal LLM support, and more, developers can build GenAI apps quickly and reliably.
  • Intelligent agent building
    Leverage the enhanced Agent Framework to build autonomous agents that respond contextually, automate decisions, and evolve with your data.

  • True AI-assisted integration development
    The copilot is now built into every step of development, assisting with logic generation, documentation, test creation, and continuous feedback—bringing the productivity of AI directly into low-code and pro-code integration development.

  • Unified visual development experience
    From low-code/pro-code integration development in BI to real-time event streaming integration development in SI, everything happens within VS Code, creating a unified way of building integrations with WSO2 Integrator.

  • Expanded connectivity
    Out-of-the-box connectors such as connectors for IBM MQ, Solace, Apache Pulsar, Salesforce Marketing Cloud, and Intelligent DocumentProcessing, among others, enable seamless interaction between traditional enterprise systems and next-generation AI-powered systems.

  • Unified observability and governance - one control plane. Total visibility
    With the latest ICP enhancements, teams gain full visibility into BI, MI, and SI runtimes. New dashboards and runtime controls make it easier to track deployments and govern integrations across environments—all from a single interface.

  • Seamless modernization and migration - accelerate your journey from legacy to modern integration
    This release introduces built-in migration tools for MuleSoft, TIBCO, and Azure Logic Apps — allowing teams to import, translate, and modernize legacy integration projects effortlessly in WSO2 Integrator. Automatic translation of flow logic, data mappings, and connector configurations helps teams modernize without starting from scratch.

Together, these features redefine WSO2 Integrator as a platform for building intelligent, composable, AI-ready applications—not just integrations.

The following are the key features included in each component of WSO2 Integrator.

1. WSO2 Integrator: BI 1.4.0

WSO2 Integrator: BI 1.4.0 transforms integration development into an intelligent, assisted, and collaborative experience, merging visual low-code design with deep AI assistance so developers can move from concept to deployment in no time.

AI-assisted developer experience

BI 1.4.0 makes AI a native part of the developer experience, not just an add-on.

The enhanced Copilot acts as an intelligent co-developer—offering context-aware suggestions, generating documentation from integration logic, and adapting based on user feedback. Enterprise users can configure their own LLMs using the “Bring Your Own Key” feature for improved control and privacy.

The enhanced Copilot now supports feedback collection, documentation generation, automated test generation, and multi-language support, helping teams accelerate development while maintaining quality and consistency.

The 1.4.0 release introduces a refreshed workspace that enhances how teams visualize, manage, and deliver integrations:

  • Integration overview gives a complete picture of components and their interactions.
  • Enhanced data mapper supports nested arrays, unions, and optional fields.
  • Type editor auto-generates JSON or XML schemas from sample payloads. 
  • Centralized configuration management keeps credentials and endpoints consistent.
  • Try-it and visual debugger tools enable instant testing and step-through troubleshooting.

With these capabilities, developers can design and maintain integrations with greater precision, speed, and confidence—supported by an AI that truly understands their project context.

GenAI App Development and AI Agents

Beyond assistance, BI 1.4.0 empowers teams to build GenAI-powered applications and autonomous agents directly within their integrations.

  • Retrieval-Augmented Generation (RAG)
    Retrieve contextual knowledge from structured and unstructured data via built-in chunkers and loaders. BI 1.4.0 includes the following built-in chunkers:
    • Generic chunker
    • HTML chunker
    • MD chunker
    • Devant chunker
  • Agent framework enhancements
    A major upgrade that makes agents smarter and more autonomous.
    • New memory implementation for storing and recalling context between executions.
    • Trim and summarization support to keep memory concise and efficient.
    • Persistent support enables agents to maintain state across sessions.
    • MCP client support for modular, context-aware agent orchestration.
    • Agent tracing support for observability and debugging of decision paths.
  • Direct LLM API
    Embed LLM interactions directly into integration flows, now supporting structured responses and multi-modal inputs such as text, images, and documents.

These advancements enable teams to build context-aware intelligent systems—from chatbots and digital assistants to document processors and monitoring agents—natively within BI.

Expanded connectivity

  • Connector discovery for 600+ systems directly inside the IDE.
  • Simplified creation of custom connectors from any OpenAPI specification.
  • Event integrations: Native connectivity for IBM MQ and Solace, enabling real-time messaging and event-driven integration across enterprise systems.

These additions strengthen BI’s ability to connect with enterprise and cloud ecosystems effortlessly, reducing integration time and complexity.
