There is no warning for this plugin in the update center that this plugin requires a newer Hudson version than at least 1.362 which we are using!

I updated the plugin from 1.14 to 1.15 version and after that our metrics job failed to finish, the graphs of the metrics job were lost, configuration page of any job in Hudson failed to load completely and it wasn't possible to trigger some jobs - so the warning about update should always be there if there is a need for it!
