WSO2 Integration Platform H1 2026 Release: What's New in WSO2 Integrator 5.0.0

WSO2 Integrator 5.0.0 is a milestone release for the WSO2 Integration Platform. It consolidates the BI, MI, and SI profiles into a single unified offering: WSO2 Integrator. The new release also introduces a set of headline improvements that meaningfully change how teams build, manage, and operate integrations.

Rather than walk through every change in this release, we want to focus on the five improvements that matter most, and explain why we made them.

1. A truly conversational way to build integrations

Integration development has always been iterative, but tooling rarely reflected that. Developers would write a requirement, generate some code, hit a wall, and start over. With WSO2 Integrator 5.0.0, that cycle changes fundamentally.

The WSO2 Integrator Copilot now supports multi-turn, conversational development. A developer describes a business requirement in natural language. The Copilot proposes an integration plan. The developer refines it (adding rules, OpenAPI specs, or constraints) across multiple exchanges. Once the plan is ready, the Copilot generates the full end-to-end integration, opens the visual diagram, and stays in the conversation to help with configuration, testing, and validation.

This isn’t prompt-and-hope. It’s a genuine back-and-forth where the developer stays in control and the AI handles the heavy lifting. The result is faster development cycles and integrations that more accurately reflect the original requirement.

2. Built-in governance for AI-driven integrations

As enterprises begin embedding GenAI into mission-critical workflows, a new problem emerges: how do you know your AI is behaving correctly? Unlike traditional integrations, AI-driven flows are non-deterministic. They can drift. They can be subtly wrong in ways that are difficult to catch without the right tooling.

WSO2 Integrator 5.0.0 addresses this with a built-in LLM evaluation framework. Teams can collect execution traces, build reusable datasets from real-world runs, and write evaluation rules (from simple assertions to LLM-as-a-judge assessments) that validate AI behavior before it reaches production.

Alongside this, the new Agent Execution Visualizer gives developers real-time visibility into what an AI agent is actually doing: which tools it’s calling, in what sequence, and how intermediate results shape the next decision. This makes debugging agents practical rather than guesswork.

Taken together, these capabilities reflect a straightforward conviction: you shouldn’t deploy AI into production without the ability to evaluate and observe it. WSO2 Integrator 5.0.0 makes that possible without leaving the platform.

3. Centralized control with the integration control plane

Managing distributed integration deployments has historically meant stitching together multiple dashboards, log sources, and access controls. The integration control plane (ICP) in WSO2 Integrator 5.0.0 changes that.

ICP provides a unified runtime dashboard with real-time health, connectivity, and metadata visibility across all environments. Operators can start and stop integrations centrally, access consolidated logs and metrics, and manage access through project- and environment-scoped RBAC with Admin and Developer roles. Authentication is handled through built-in login, OIDC-based SSO, and external user store support.

The goal is simple: one place to govern everything. Whether you’re running integrations across cloud, on-premises, or hybrid environments, ICP gives you the visibility and control to operate confidently at scale.

4. Reliable file processing at scale

File-based integration sounds simple until you try to run it reliably in a distributed environment. Race conditions, duplicate reads, and failed recoveries are common problems that teams work around rather than solve. WSO2 Integrator 5.0.0 addresses these directly.

A new coordination model ensures that only a single processing node handles any given file at a time, preventing duplicate reads and race conditions in clustered deployments. Automatic failover means that if a node goes down mid-processing, another node picks up seamlessly without compromising data integrity.

CSV processing has also been overhauled. Where the previous approach would reject an entire file on a single malformed row, the new fail-safe model continues processing valid records, isolates the problematic ones, and surfaces diagnostics to reduce manual investigation. Streaming support means large files are processed row by row without loading everything into memory.

These improvements make WSO2 Integrator a more dependable foundation for mission-critical batch processing and data pipelines.

5. Expanded connectivity: Solace, CDC, and beyond

Modern integration strategies depend on connecting the technologies enterprises already rely on, across APIs, events, and data systems. That’s why this release expands WSO2 Integrator’s connectivity for modern event-driven and real-time architectures.

A major addition is native support for Solace PubSub+, enabling organizations to connect WSO2 Integrator directly into their event mesh environments. With support for guaranteed messaging, message persistence, and fine-grained access control, teams can build and manage real-time event flows without custom workarounds or added complexity.

This release also extends Change Data Capture (CDC) support to Microsoft SQL Server and PostgreSQL, broadening the range of enterprise systems that can participate in event-driven architectures. To improve operational reliability, liveness and readiness checks for CDC listeners have also been introduced, helping ensure stable deployments in Kubernetes and other orchestrated environments.

Together, these enhancements reinforce a core principle behind WSO2 Integrator 5.0.0: integration platforms should adapt to existing enterprise ecosystems, making it easier to connect applications, events, and data wherever they already live.

First, native Solace PubSub+ support. Organizations running Solace as their central event mesh can now connect WSO2 Integrator directly, with support for guaranteed messaging, message persistence, and fine-grained access control. This makes WSO2 Integrator the integration layer for real-time event flows without workarounds.

Second, Change Data Capture (CDC) now supports Microsoft SQL Server and PostgreSQL, two of the most widely used enterprise databases. This broadens the range of systems teams can integrate with in event-driven architectures. Liveness and readiness checks for CDC listeners have also been added, ensuring stable operation in Kubernetes and other orchestrated environments.

Together, these connectivity improvements reflect a consistent priority: meet teams where their systems are, not where we’d prefer them to be.

Additional improvements

Beyond the five headline areas above, WSO2 Integrator 5.0.0 includes a range of further enhancements across the platform.

• JDK 25 compatibility, enabling the platform to leverage the latest Java performance and security improvements.
• Agent Framework upgrades with MCP support, persistent memory, and summarization, enabling context-aware autonomous agents within integration flows.
• Built-in Agent ID integration for identity and access management of AI agents, with runtime security validation enforced automatically during tool execution.
• WSO2 Integrator 5.0.0 also brings enhancements to the MI profile with the release of WSO2 Integrator: MI 4.6.0. which introduces:
  • Enhanced RAG capabilities, with support for vector databases (Weaviate, Milvus) and Azure OpenAI embedding models, plus a new WSO2 model provider available at no additional cost.
  • Full OpenTelemetry support (metrics, traces, and logs), with Prometheus 3.5.0 compatibility and Moesif integration.
  • Remote debugging via the VS Code extension, Synapse unit test coverage reporting, and workspace-level build and run with multi-module project support.
  • With the new Agent mode, the platform can autonomously design integrations, deploy artifacts, test flows, and generate test cases, helping developers move faster with less manual effort. Amazon Bedrock login support also simplifies access to external foundation models and enterprise AI capabilities.
  • AMQP 1.0 protocol support, a gRPC connector with import support, nested and reusable queries in Data Services, and optimized Ballerina-to-MI connector conversion.
  • Enterprise-grade security improvements including FIPS-certified cryptography (Bouncy Castle FIPS provider), built-in OAuth 2.0 and JWT validation handlers, and post-quantum cryptography capabilities.
