**OpenTSDB breaking change**
-[Issue #1438](https://github.com/grafana/grafana/issues/1438). OpenTSDB: Automatic downsample interval passed to OpenTSDB (depends on timespan and graph width)
- NOTICE, Downsampling is now enabled by default, so if you have not picked a downsample aggregator in your metric query do so or your graphs will be missleading
- This will make Grafana a lot quicker for OpenTSDB users when viewing large time spans without having to change the downsample interval manually.
