#### BC Breaking Changes

- Removed `showFooter` from `panel` array configuration. This can be now configured with `footer` option within the `panel`.
- Removed `layout` from `panel` array configuration. This can be now configured with `panelTemplate` at the GridView level.
- Renamed `beforeTemplate` property to `panelBeforeTemplate`.
- Renamed `afterTemplate` property to `panelAfterTemplate`.
- Renamed `beforeContent` tag used in `panelBeforeTemplate` to `before`.
- Renamed `afterContent` tag to `panelAfterTemplate` to `after`.
- EditableColumn attribute naming convention has changed. Developers do not need to use `Model::loadMultiple` method anymore and have the ability to directly use the `$model->load` method.

#### Additions
- Templates have been simplified and consolidated to the following configurable properties:
    - `panelTemplate`: Template to render the complete grid panel.
    - `panelHeadingTemplate`: Template to render the heading block part of the panel.
    - `panelBeforeTemplate`: Template to render the before block part of the panel.
    - `panelAfterTemplate`: Template to render the after block part of the panel.
    - `panelFooterTemplate`: Template to render the footer block part of the panel.
- The `heading`, `footer`, `before`, and `after` properties in the `panel` typically accepts a string to render in that particular block. All of these can be set to boolean `false` to hide them.
