 |   2.18  | Bug fix for reporting activity metrics that might be `null` sometimes. This is unsimulatable situation, so this version is a change based on an informed guess. |
 |   2.19  | A template to evaluate is now optionally allowed on both `group` and `toggle` menu items. The template to evaluate is non-optional on a `template` menu item. All updates are performed in a single HTTP GET request for efficiency. Bug fix for negative heading values. Vibration now (optionally) confirms toggle menu items being tapped. |
 |   2.20  | Simplified the code base now that templates have been requested in all menu items. This means the `template` menu item became a superset of `tap`. Therefore the `tap` code has been has been upgraded to include `template` and the latter deprecated. JSON menu definitions continue to support `template` items by instantiating a `tap` menu item, but the schema marks them as deprecated and users should migrate their menu definitions now.
