- Telegram/Codex: keep message-tool-only progress drafts visible and render native Codex tool progress once per tool instead of duplicating item/tool draft lines. Fixes #75641. (#77949) Thanks @keshavbotagent.

- Telegram: keep duplicate message-tool-only Codex turns from posting generic silent-reply fallback text, so private finals stay private after inbound dedupe. Thanks @rubencu.

- Telegram/sessions: gap-fill delivered embedded final replies into the session JSONL even when the runner trace is missing, so Telegram answers after tool calls do not vanish from the durable transcript. Fixes #77814. (#78426) Thanks @obviyus, @ChushulSuri, and @DougButdorf.

- Providers/xAI: stop sending OpenAI-style reasoning effort controls to native Grok Responses models, so `xai/grok-4.3` no longer fails live Docker/Gateway runs with `Invalid reasoning effort`.

- Providers/xAI: clamp the bundled xAI thinking profile to `off` so live Gateway runs cannot send unsupported reasoning levels to native Grok Responses models.

- Matrix/approvals: retry approval delivery up to 3 times with a short backoff so transient Matrix send failures do not strand pending approval prompts. (#78179) Thanks @Patrick-Erichsen.

- Agents/reasoning: keep embedded reasoning deltas raw for correct same-line streaming while preserving formatted Telegram, Feishu, Discord, and heartbeat delivery at the channel edge. (#78397) Thanks @medns.

- Agents/failover: rotate auth profiles before deferred cooldown marking on rate-limit failures, so file-lock contention cannot stall profile failover. Fixes #57281. (#57283) Thanks @jeremyknows.

- Gateway/sessions: when `session.dmScope: "main"` is configured, route a bare webchat `/new` against the agent's main session (`sessions.create` with `emitCommandHooks=true`) to an in-place reset instead of creating a parallel `dashboard:` child, matching `/new` behavior on Telegram/Discord. Fixes #77434. (#71170) Thanks @statxc.
