Version 1.18.2.12

Release Date: September 21, 2026 Release Type: Stable Previously published as: 1.18.28 (image tag staging-1.18.28)

Fixes JDBC and MongoDB connector steps reporting "Queue full" errors after the first 1000 messages.

JDBC and MongoDB connector steps no longer report "Queue full" after 1000 messages: JDBC and MongoDB connector steps that produce CSV, JSON or XML output kept an internal copy of every message that was never released. After 1000 messages per backend instance, every further message through such a step was marked as ERROR with the message "Queue full" until the instance was restarted. The database operations themselves completed and the logs stayed complete; only the reported flow status was wrong. These steps now run without this limit.

1.18.2.12 is a stable release. Previous: 1.18.2.11
