v0.3.0

Release Notes

v0.3.0

This release simplifies the local backend surface, hardens long-running session reliability, and aligns the entire app on the new DeepSeek model identifier and the renamed happy CLI runtime.

Highlights

• Added a processing watchdog so long-running Happy sessions cannot silently hang. Stale "processing" state is detected, surfaced as an error, and recovered automatically.
• Added a service discovery and conflict resolution module: the Electron app and CLI can now probe ports, attach to a compatible existing local service, and report richer service status.
• Added improved JS Eyes extension installation and connection guidance, including token-based pairing and compatibility notes, in both the renderer and the docs app.
• Updated the default DeepSeek model identifier to deepseek-v4-pro[1m] everywhere (renderer, docs app, blog post, user settings, model config, settings UI, setup wizard).
• Updated CLI commands (start, stop, status, open) to consume the new discovery module and produce clearer status output.

Removed

• Removed the entire legacy browser-control server module, including its Express routes, WebSocket server, auth/audit/rate-limit/database layers, browser panel, scenarios, and supporting docs and skills. The integration is now done through the JS Eyes extension.
• Removed deprecated configuration and skill files (config/config.json, config/default.js, browser-control skills under deploy/skills/..., obsolete CLAUDE.md skill guides) left over from earlier server modes.

Internal updates

• Refactored the CLI build to track the renamed happy runtime instead of happy-coder, including new ACP/persistence bundles and updated message normalizer modules in both the renderer and docs app.
• Refactored installation and dependency-checker logic so the setup wizard and settings produce consistent install/upgrade feedback against the renamed happy runtime.
• Bumped versions in package.json, packages/cli/package.json, README files, renderer, and docs app to 0.3.0.

Notes

• Existing local checkouts should run npm install (and cd packages/cli && npm install) so the renamed happy runtime, new bundled tools (ripgrep, difftastic), and updated lockfiles are picked up cleanly.
• The legacy browser-control routes and panel are gone. If you depended on them, switch to the JS Eyes extension based flow as documented in the setup wizard and READMEs.
• Run npm run check:web-sync after pulling to confirm docs/app is still in sync with the renderer sources, and npm run check:claude-detector to validate Claude Code detection on your machine.
