v0.51.3
July 17, 2026
Reliability and isolation: external systems connected to your flows no longer receive duplicate deliveries when an internal job is retried, and data isolation between organizations is now guaranteed "by construction" at the database access layer.

Improvement
No duplicate deliveries on retries
The internal job queue guarantees no delivery is lost, but until now a crash at the wrong moment could re-fire a webhook call or an email that had already gone out. Every delivery to external systems is now recorded and a retry skips it: no double emails, no duplicate webhooks. A genuinely failed delivery is still retried as before.

Security
Stronger isolation between organizations
Every API request now operates on a database access bound to its own organization: reads are filtered automatically, an identifier belonging to another organization simply appears not to exist, and a write outside your perimeter is rejected. A structural guarantee, covered by dedicated tests, layered on top of the checks already present in individual features.
