- Agent avatars: first-letter + deterministic color avatar in all views
- Agent management: edit (name/description) and delete with confirmation
- Execution API: validates agent existence, returns 410 if deleted
- Task tags: JSON array field, editable with tag pills UI
- Task search: by name (?q=) and by tags (?tags=) and by status
- Task edit: simplified to name/tags/description only (not agent params)
- Cron display: human-readable Chinese (e.g. '每5分钟', '每天 09:00')
- Timezone fix: UTC→local via dayjs.utc().local() across all pages
- Content area: full width (removed max-width:1200px constraints)
- Login page: standalone layout without sidebar
- fix(api): heartbeat endpoint no longer requires request body, fix spa_fallback
404 handler causing 500 on API routes, add db.refresh() in agent update/heartbeat
- feat(time): unify all frontend time display to Beijing time (Asia/Shanghai)
via new beijing() utility; backend alert messages also use BJT
- feat(ui): collapse AI agent instruction panel on Tasks page by default
