AI Configuration panel — new section in agent settings. Toggle between System Proxy and Own Key in one click. Provider list comes from backend (not hardcoded). API key stored securely with change flow. Changes apply to running agents immediately.
Unified agent card — was rendering differently on workspace page, agent list, and agent detail. Now it's one component everywhere. Start/Stop/Restart/Chat/Delete buttons always visible. Inline name and description editing.
Webchat wake — if you message a sleeping agent via web chat, you now see a friendly notification instead of silence. Auto-retries every 30s for up to 2 minutes.
Discord & Slack wake — wake notifications were Telegram-only. Now work on Discord and Slack too. Localized (EN, RU, ES).
Fixes: channel added to running agent stayed Pending forever; config changes on stopped agents lost on start; API key not sent on first own_key setup.
