+## 1.4.0 — 2025-12-03
 
 ### Highlights
 - **Thinking directives & state:** `/t|/think|/thinking <level>` (aliases off|minimal|low|medium|high|max/highest). Inline applies to that message; directive-only message pins the level for the session; `/think:off` clears. Resolution: inline > session override > `inbound.reply.thinkingDefault` > off. Pi/Tau get `--thinking <level>` (except off); other agents append cue words (`think` → `think hard` → `think harder` → `ultrathink`). Heartbeat probe uses `HEARTBEAT /think:high`.
-- **Group chats (web provider):** New `inbound.groupChat` config (requireMention, mentionPatterns, historyLimit). Warelay now listens to WhatsApp groups, only replies when mentioned, injects recent group history into the prompt, and keeps group sessions separate from personal chats; heartbeats are skipped for group threads.
+- **Group chats (web provider):** Warelay now fully supports WhatsApp groups: mention-gated triggers (including image-only @ mentions), recent group history injection, per-group sessions, sender attribution, and a first-turn primer with group subject/member roster; heartbeats are skipped for groups.
 - **Group session primer:** The first turn of a group session now tells the agent it is in a WhatsApp group and lists known members/subject so it can address the right speaker.
 - **Media failures are surfaced:** When a web auto-reply media fetch/send fails (e.g., HTTP 404), we now append a warning to the fallback text so you know the attachment was skipped.
 - **Verbose directives + session hints:** `/v|/verbose on|full|off` mirrors thinking: inline > session > config default. Directive-only replies with an acknowledgement; invalid levels return a hint. When enabled, tool results from JSON-emitting agents (Pi/Tau, etc.) are forwarded as metadata-only `[🛠️ <tool-name> <arg>]` messages (now streamed as they happen), and new sessions surface a `🧭 New session: <id>` hint.
