v1.0.0

First release as Heatmap Card Continued.

Thanks to @kandsten for the original card and for graciously allowing this continuation.

Added

• Custom threshold editor in the visual editor - build color scales without editing YAML
• Configurable legend decimal places via display.decimals config option
• Fahrenheit temperature color scales for all four built-in temperature scales

Changed

• Removed esbuild build system; all source modules merged into a single deployable heatmap-card.js with no build step required
• Replaced broken mwc-tab-bar scale picker UI with a flat ha-select dropdown showing all built-in scales with gradient previews
• Replaced ha-combo-box elements with ha-select throughout the editor for reliable rendering in current HA versions
• Inlined chroma.js, scale data, and device class mappings directly into the card file

Fixed

• Null values in min_from/max_from were coercing to 0 in Math.min/Math.max, skewing auto-scaled range for sensors with data gaps
