 ### Breaking changes
 
-The default menu placement for the `Select` component was previously set to `auto`. This meant that the drop down for the select would open downwards/upwards depending on available space. We've noticed that the `auto` doesn't always work when the drop down for `Select` is opened upwards so therefore we've changed the default to `bottom` instead.

This new graph visualization uses the new panel architecture introduced in Grafana 7.0 and integrates with field options, overrides, and transformations.
 
 The Time series beta panel implements the majority of the functionalities available in the current Graph panel. Our plan is to have close to full coverage of the features in Grafana 8.0, coming later this year.
 
 Apart from major performance improvements, the new Time series panel implements new features like line interpolation modes, support for more than two Y-axes, soft min and max axis limits, automatic points display based on data density, and gradient fill modes.
