This is just a small bug fix release of the plugin. It was actually quietly released for a while now of if you have downloaded the plugin recently, you have the latest version. To be sure — check the version in the Console or you will see it in the file name.
There are two bugs fixed:
1. Deployment on an OMS hosted on Solaris didn’t work (and suspect could be the same for Agents on Solaris).
2. Changing thresholds on the metrics caused an error “Modification of Target Monitoring Settings has Failed”. Also applying monitoring template was failing for the same reason.
If you did’t know that you can setup threshold and customized the thresholds that are set out of the box with the plugin then you are not using full capabilities of the Enterprise Manager. You can do that in the MySQL target menu — Monitoring -> Metric
