Breaking changes
Style breaking changes
The card style is now aligned with the Tile card.
- Mushroom theme variables and colors are no longer applied, since the card now uses the same components and styles as the Tile card.
- Icons will only display a background when an action is assigned to them, making it clearer when they are interactive (2025.3: View those headers! - Home Assistant).
Breaking Changes for Card Mod Users
Due to the Template Card redesign, its internal structure has changed. This will break existing Card Mod customizations.
Backward compatibility
A Legacy Template Card is available to preserve the old behavior and style :
- the UI editor will allow you to revert to legacy card in one click
- in
yaml, you only have to replacecustom:mushroom-template-cardbycustom:mushroom-legacy-template-card
