v3.0.0

3.0.0 — 2026-05-12

Breaking Changes

Upgrading from v1.x or v2.x requires the following changes:

• Card type renamed: Change type: custom:nws-alerts-card → type: custom:weather-alerts-card in your dashboard YAML (v1.x users only — already done if you migrated to v2).
• headline key removed: Rename headline: → deduplicateHeadlines: in any card configs that still use the old key (v1.x users only).
• Manual install resource renamed: Update your HA resource path from /local/nws-alerts-card.js to /local/weather-alerts-card.js. HACS users: no action needed.

See the README migration guide for full details.
