The developers of FreeNAS have made available the 4th update to FreeNAS 11.2. **11.2-U4.1 hot-fix release is now available to address an alert services error**. This release has several security fixes and feature improvements to the UI. There is a known plugin issue where if you try to install another instance of the plugin, the dataset from the first will be attached and deleted, so be aware of that. That fix will come by FreeNAS 11.3. See the link below for the full release notes.
Users of 11.2 systems are encouraged to update to 11.2-U4 using the instructions in the Guide.
