### Version 2.1.4 2024-09-03
{% file src="" %}
{% hint style="warning" %}
Starting with version 2.1.4, the addinStop() method must be implemented to ensure proper termination of the add-in. During shutdown—either triggered by the server or manually—the main JAddin thread invokes addinStop() and, if necessary, issues a Thread.interrupt() to stop running threads. Note that the Domino server may not shut down cleanly if background threads remain active.
