v1.7.0

Visual Verification (Screenshot Tool)

• New screenshot_url MCP tool — takes screenshots of any Home Assistant frontend page using headless Chromium, enabling AI models with vision capabilities to visually verify dashboard changes, card layouts, and UI modifications
• Three-layer authentication — uses localStorage token injection, WebSocket auth interception, and HTTP request header injection to reliably authenticate with the HA frontend regardless of version
• Opt-in via configuration — disabled by default to keep resource usage minimal. Enable via the screenshot_enabled option in the add-on Configuration tab
• Requires Long-Lived Access Token — uses the same access_token option already available for ESPHome tools to authenticate with the HA frontend
• Configurable viewport — supports custom width, height, render wait time, and full-page capture
• HA Core URL auto-discovery — extracted into a reusable discoverHACoreUrl() function shared with the ESPHome ingress discovery logic
• Chromium and puppeteer-core added to the container image

MCP Server

• 34 tools (was 33) — screenshot_url added to the tool set
• MCP server version bumped to v2.7.0
• New createImageContent helper in lib/helpers.js for building MCP image content objects

CI/CD

• New dev branch for beta development — beta releases are now tagged and built from dev, stable releases from main
• Beta release workflow now syncs the entire ha_opencode_beta/ directory (config, translations, changelog, docs) from dev to main automatically
