October 2025

10 Commits • 3 Features

Oct 1, 2025

October 2025 focused on strengthening security, improving access control, and ensuring data integrity across the n8n platform and its documentation, driving measurable business value through safer defaults and clearer guidance. In n8n, delivered: - Access Control and Role Management Improvements: explicit access control test suite, scope-based restriction of user properties, and clarified project role descriptions. - Security Exposure Controls and Integration Enhancements: configurable invite link exposure, conditional OIDC scopes for provisioning, and a corrected benchmark webhook endpoint. - Database Schema Migrations and Data Integrity: migration of insights value column to BIGINT to prevent overflow and enforcement of unique display names for roles, with services updated to gracefully handle potential unique constraint errors. In n8n-docs, documented security-related configurations, including: - Credential overwrite token usage with a practical curl example and stronger security guidance, and - N8N_INVITE_LINKS_EMAIL_ONLY to restrict invite links delivery to email-based access. Overall, the month delivered stronger security posture, improved data integrity, more reliable benchmarking, and clearer operator/developer guidance, contributing to reduced risk, improved compliance readiness, and faster onboarding for new users and contributors.

September 2025

21 Commits • 7 Features

Sep 1, 2025

September 2025 delivered substantial improvements across authentication, authorization, and reliability for nocodb/n8n-fork and n8n. Key features introduced include dynamic OIDC configuration management across multi-main deployments, enhanced OIDC authentication with configurable prompts and owner-based login controls, and licensing-driven role features with dynamic resolution. Cross-instance SAML configuration reloads were added, and credential handling was strengthened with secure export and per-project/role associations. In addition, quality and reliability improvements—improved startup error logging, translation optimizations, and more robust test coverage (including MySQL retry tests and benchmark realignment)—reduced operational risk and improved maintainability. These changes collectively deliver clearer error visibility, stronger access governance, faster rollout of identity-related changes, and measurable business value in reliability and security.
