n8n 2.16.0 released with Notion OAuth, durable Wait nodes
n8n's latest release adds Notion OAuth support, makes Wait nodes fully durable, enables browser automation, and expands token exchange capabilities for enterprise users.
n8n 2.16.0 is now available, bringing 24 new features, 20 bug fixes, and a performance improvement to the workflow automation platform.
The release introduces Notion OAuth support, allowing users to authenticate with Notion using the OAuth flow rather than API keys alone. The Wait node has been made fully durable, removing an in-memory execution path that could cause issues during server restarts. Browser automation capabilities have expanded with the @n8n/mcp-browser package reaching 1.0.0 status.
For enterprise deployments, the token exchange service now includes JWT issuance and a JTI store for atomic token consumption and cleanup. Community package management is now available via the Public API, enabling programmatic installation of custom nodes. Data redaction settings are now generally available after being behind a feature flag.
The expression engine received performance improvements through isolate pooling, which reuses VM contexts rather than creating new ones for each evaluation. Workflow node tracing via OpenTelemetry is now available for debugging complex execution paths.
New nodes include the Alibaba Cloud Chat Model node, while the Pipedrive node received a v2 update supporting API v2. The Chat Trigger node gains auto-highlighting of execution data for easier debugging.
