+
+1. **Composer Per-Conversation Approval Modes**: [Composer](/composer) now lets you choose when each conversation pauses for approval: ask before all changes, allow creates but ask before updates, deletes, runs, or publishing, bypass approvals entirely, or set custom permissions by resource and action.
+
+2. **Eval Run History**: You can now browse your complete [Eval run history](/observability/evals-quickstart#view-run-history) with search and pagination, and share a specific run result by URL.
+
+3. **Fixes and Improvements**:
+    - **Call logs**: The logs table now shows clearer, deterministic error messages for 4xx responses instead of retrying unnecessarily, and the date picker now lets you select the full retention window.
+    - **Voice fallback**: xAI terminal voice failures raised before a call starts are now delivered, the fallback voice no longer greets out of turn, and replacing a voice no longer consumes a second fallback.

-### No deletion capability
+### Approval modes
 
-Composer **cannot delete any resources** — assistants, tools, phone numbers, squads, files, or anything else. This is a deliberate safety measure, not a limitation.
+You choose when Composer pauses for your approval, and the setting persists for that conversation:
 
-If you ask Composer to delete something, it directs you to do it yourself:
+- **Ask before every change**: Composer requests approval for all creates, updates, deletes, runs, and publishes.
+- **Ask before updates, deletes, runs, and publishing**: Composer creates new resources on its own, but asks before changing, deleting, running, or publishing anything that already exists.
+- **Bypass approvals**: Composer applies changes without pausing.
+- **Custom**: set permissions for each resource and action individually.

-Composer: "I'm not able to delete resources to prevent accidental data loss.
-You can delete it yourself from the dashboard — use the sidebar on the left,
-go to Assistants, select the one you want to remove, and delete it from there."

-<Note>
-Unlike creating or updating a resource (which can be undone or re-done), deletion is permanent. Requiring manual confirmation through the dashboard UI prevents accidental loss of important configurations.

-### Approval required for updates
+### Deletion
 
-When Composer modifies an existing resource (like updating an assistant's prompt, changing a voice setting, or editing a tool configuration), it pauses and asks for your explicit approval first.
+Composer can delete resources such as assistants, tools, phone numbers, squads, and files. Deletion follows your approval mode: unless you have selected Bypass, Composer asks for your explicit approval before it deletes anything. Because deletion is permanent, keep an approval mode on if you want a confirmation step before a resource is removed.

 **Key details about approvals:**
 
-- **Tokens expire after 10 minutes** — if you don't respond in time, Composer needs to re-propose the change
-- **Each approval is specific** — approval tokens are cryptographically bound to the exact change being made; multiple updates each require individual approval
-- **Read operations don't require approval** — Composer can freely read and list your resources without permission
-- **Creating new resources doesn't require approval** — new assistants, tools, and other resources are additive and non-destructive
