  +## [2.2.0] - 2017-11-13
  - Added a concept of edit actions, which are like fixes with caveats. These need explicit user intent to apply because they may change the code's API, or otherwise be unsafe.
  - Support warning about and automatically fixing some simple uses of some 1.0 elements to their 2.0 usage styles.
  - To add this fixable lint warning for your own elements, simply add the `old-content-selector` attribute to your new `<slot>` element. Set its value to the value that your old `<content>` element had for its `select` attribute.
