✨ New Features & 🐛 Bug Fixes

✨ What's New

📅 Date Picker — rolling "Last N" ranges

Pick a rolling window that always ends at now: Last 24H, 3D, 7D, 15D, 30D, 90D, 180D, 12M. Set one as the view the card opens on, or add them as buttons next to D / W / M / Y. The ◀ ▶ arrows jump a whole period at a time. The classic Day / Week / Month / Year buttons are unchanged.

📡 Attribute history in State Timeline (#219)

A State Timeline row can now show the history of an attribute instead of the entity's state — perfect for things Home Assistant already records, like a TV's current app, a Wi-Fi band, or a thermostat's heating/idle action. Just choose the attribute and list its values in the State Map. No template sensor needed.

🎨 Per-state colours in the editor

The State Map field now accepts value, label, color, so you can give each state its own colour right in the visual editor — no YAML required. Ideal for making every State Timeline segment a different colour.

↕️ Tooltip order & a unit on the Total (#221)

A new Tooltip Order option (Overlay → Tooltip) lets you list tooltip rows as Default, Reverse (matches a stacked chart top-to-bottom), or Alphabetic. The Total row now also shows the unit (e.g. 6.20 kWh) when every entity shares one.

🕓 Tooltip date can match the axis (#215)

Switch on Tooltip Date = Axis (Overlay → Tooltip) to make the tooltip's date read just like the X-axis — e.g. May 26 on long-range views instead of a full timestamp.

🔤 More date formats

New ready-made formats, including month names that follow your dashboard's language (MMM YY → May 26 in English, Mai 26 in German) and ISO styles like YYYY-MM-DD.

🪜 State Timeline X-axis labels (#218)

State Timeline now has the same X-axis label controls as Timeline — size, opacity, colour, and a separate colour for date labels — under the X Axis tab.

〽️ Labels on moving-average lines

Each moving average can show a small MA7 / MA26 label at the end of its line. Turn it on per line, next to the colour picker.

🐛 Fixes

• State Timeline now matches HA's History (#208) — states are drawn as real segments at their actual change times instead of being merged or dropped, and it stays accurate at any Points/Hour.
• Colour variables in Pie & more (#217) — color: var(--my-colour) now works in Pie, Radial Bar, Polar Area, Radar and Ranking, not just Timeline.
• Clean 12 months in Year view (#216) — a year grouped by month no longer shows an extra empty column for next January.

Updating: Home Assistant caches the card aggressively — after updating, hard-refresh your browser ctrl+shift+R, or clear cache via menu
