July 2026 monthly summary: Focused on strengthening security and improving testing and documentation around certificate-based authentication for Microsoft OAuth2 credentials and Entra Service Principal in n8n, along with documenting the process for users. No major bugs documented in the provided scope.

June 2026 delivered security-focused authentication enhancements and cross-repo reliability improvements across nocodb/n8n-fork, n8n, and docs. Key work includes redaction policy enforcement for new workflows with end-to-end tests, flexible Microsoft OAuth2 credentials for OneDrive, Graph-based OAuth2 credentials for Excel/Outlook, certificate-based client authentication via private_key_jwt, and a PEM handling refactor to standardize encoding. These changes improve data protection compliance, simplify integration with Microsoft Graph, and strengthen security while maintaining backward compatibility.

Month: 2026-05 | Repository: n8n-io/n8n Summary: Delivered API alignment for workflow credentials. The /credentials/for-workflow endpoint now returns data shaped to match the frontend's expected type, eliminating the prior typing mismatch that caused UI friction when accessing credentials in workflows. This work, tied to issue #31253 and implemented in core via commit 1c3901576bb4b2e266ce7a21933221204f44064a, strengthens end-to-end reliability and reduces onboarding friction for automation builders.
