# Release 5.19.1

Release 5.19.1 is a fix release on top of 5.19.0. It removes a stuck lock on knowledge base export and import in Fast Line Pro.

## Fast Line Pro

**Fixed**

- **Knowledge base export and import are no longer blocked after a finished or interrupted task.** Previously, after a platform update, a failure or a restart during a task, the next export or import could fail for up to a day as if another task were still running, although it had already finished. Now such a lock is cleared and a new export or import starts right away.
  - The "one task per user at a time" limit works as before: while the previous task is actually running, a new one cannot be started.
