What's New
v1.13.0 is a major platform release adding integrations/connections, triggers, enterprise admin, and migration tooling.
Breaking Changes
- New database entities and migration tooling (preflight, write pause, child-process migration runs) imply schema changes that must be applied before serving traffic.
- Connection resolution now happens per execution principal through the new lfx contract, which can change which credentials existing flows use.
- Trigger execution depends on a dedicated listeners process, so existing deployment topologies need updating to run it.
New Features
- Integrations and connections layer with a persistent connection API, delegated OAuth brokering, capability manifests, and policy-governed providers and actions.
- Triggers subsystem with an event ledger, leased dispatcher with retries and dead-lettering, schedule and inbound webhook triggers, and Slack/Microsoft/Google event sources.
- Enterprise administration covering team/user APIs and CLI, directory provenance, pre-creation hooks, per-resource access exceptions, audit logging, and GDPR erase/request handling.
- Operational migration tooling: SQLite-to-Postgres conversion, file and knowledge-base relocation, integrity checks, preflight validation, and a guided Migration settings page.
- New bundles and components including FunASR, Plivo, Serply, Serping, Figranium, and Google Workspace/Microsoft/Slack connection-backed bundles.
Improvements
- Korean localization added to the UI.
- Multi-user editing safety improvements for concurrent flow editing.
- Background job metrics exposed for operational monitoring.
- Dedicated listeners process separates trigger event handling from the main app.
- GA validation added for dedicated integrations under policy-bundle governance.
Upgrade Notes
Back up the database, then run migration-preflight and check-integrity before applying the schema changes, using write pause and child-process migration runs to avoid partial writes. Review connection and credential resolution behavior for existing flows, since resolution is now per execution principal and governed by policy bundles. Deploy the dedicated listeners process if you intend to use triggers, and verify OAuth broker configuration for connection-backed bundles.

Oct 22, 2026· 5 days ago
Langflow 1.13.0 is a large platform release that introduces a full integrations and connections layer (persistent connections, delegated OAuth brokering, per-principal resolution, and policy governance), a new triggers subsystem with a leased dispatcher, webhook ingress, and Slack/Microsoft/Google event sources, plus enterprise administration, audit logging, and GDPR tooling. It also adds substantial operational capabilities for self-hosted deployments, including SQLite-to-Postgres conversion, knowledge base and file relocation, migration preflight/integrity checks, and a guided migration UI. Alongside this, the release ships new bundles and components (FunASR, Plivo, Serply, Serping, Figranium), Korean localization, multi-user editing safety, and background job metrics.
