Warning!
This release is not compatible with the dashboard configuration of previous releases.
You should update your configuration as follows:

Areas

• Remove the dash (-) in front of any options > areas > name property.
• Add a line above this name property with the id of the area, followed by a colon (:).
• Make sure you have correct indentation.

# From
options:
  areas:
    - name: Family Room
    ...
  ...

# To
options:
  areas:
    family_room_id:
      name: Family Room
      ...
    ...

Views

• Rename the domain from plural to singular noun (lights > light, switches > switch, etc).
• Remove the boolean value after the colon(:).
• Add properties on the lines below.

# From
options:
  views:
    lights: true
    switches: true
    ...

# To
options:
  views:
    light:
      order: 0
      title: Illimination
      ...
    switch:
      order: 1
      hidden: true
      icon: mdi:toggle-switch
      ...
    ...

Fixes

• Fix several errors in the readme.
• Fix getCountTemplate method.
  The method only counted states which aren't equal to value off.
• Fix overriding sensor card configuration.
  Having an entity_config property in the strategy options resulted in overriding each sensor card.
  Only the cards listed under this property should be overridden.
• Cut redundant variables and constants.
• Fix undefined sensorState.

New Features

• Undisclosed Area.
• Ordering of area cards.
• Sorting of entities by original_name.
• Sorting of areas by order and name.
• Sorting of domains by order and title.
• Overriding properties of views.
• Overriding properties of domains.
• Overriding properties of areas.
• Hide, views, domains, areas and entities.

Please consult the readme for how to configure the strategy.

Known Issues

• Title cards or chips won't switch entities assigned to the undisclosed area (#26).
