FDC3 3.0.0-alpha.2 released!

[Yannick Malins]

The FDC3 Maintainers are pleased to announce the availability of FDC3 3.0.0-alpha.2.

This alpha release represents another important milestone towards FDC3 3.0, the next major evolution of the Financial Desktop Connectivity and Collaboration Consortium (FDC3) standard.

Building on the browser interoperability work introduced in the 2.2 series, FDC3 3.0 focuses on making interoperability more secure, more observable, and better suited to modern application architectures and AI-driven workflows.

What's New

FDC3 3.0 continues to evolve around four key themes:

• Security by Design – strengthening trust between applications with identity, provenance and message integrity becoming first-class concerns.
• Observability – making it easier to understand, audit and troubleshoot application interactions.
• Cross-Firm Interoperability – enabling trusted workflows across organizations and platforms.
• Modern Usage Scenarios – supporting browser-based applications, APIs, services and AI agents alongside traditional desktop applications.

While this is an alpha release intended for evaluation and early feedback, it gives implementers the opportunity to experiment with the direction of the standard before the final 3.0 release.
