 ### Changes
 
+- Agents/Thinking defaults: set `adaptive` as the default thinking level for Anthropic Claude 4.6 models (including Bedrock Claude 4.6 refs) while keeping other reasoning-capable models at `low` unless explicitly configured.
 - Gateway/Container probes: add built-in HTTP liveness/readiness endpoints (`/health`, `/healthz`, `/ready`, `/readyz`) for Docker/Kubernetes health checks, with fallback routing so existing handlers on those paths are not shadowed. (#31272) Thanks @vincentkoc.
 - Android/Nodes: add `camera.list`, `device.permissions`, `device.health`, and `notifications.actions` (`open`/`dismiss`/`reply`) on Android nodes, plus first-class node-tool actions for the new device/notification commands. (#28260) Thanks @obviyus.
 - Discord/Thread bindings: replace fixed TTL lifecycle with inactivity (`idleHours`, default 24h) plus optional hard `maxAgeHours` lifecycle controls, and add `/session idle` + `/session max-age` commands for focused thread-bound sessions. (#27845) Thanks @osolmaz.

 - Cron/Delivery mode none: send explicit `delivery: { mode: "none" }` from cron editor for both add and update flows so previous announce delivery is actually cleared. Landed from contributor PR #31145 by @byungsker. Thanks @byungsker.
 - Cron editor viewport: make the sticky cron edit form independently scrollable with viewport-bounded height so lower fields/actions are reachable on shorter screens. Landed from contributor PR #31133 by @Sid-Qin. Thanks @Sid-Qin.
 - Agents/Thinking fallback: when providers reject unsupported thinking levels without enumerating alternatives, retry with `think=off` to avoid hard failure during model/provider fallback chains. Landed from contributor PR #31002 by @yfge. Thanks @yfge.
-- Agents/Thinking defaults: set `adaptive` as the default thinking level for Anthropic Claude 4.6 models (including Bedrock Claude 4.6 refs) while keeping other reasoning-capable models at `low` unless explicitly configured.
 - Ollama/Embedded runner base URL precedence: prioritize configured provider `baseUrl` over model defaults for embedded Ollama runs so Docker and remote-host setups avoid localhost fetch failures. (#30964) Thanks @stakeswky.
 - Agents/Failover reason classification: avoid false rate-limit classification from incidental `tpm` substrings by matching TPM as a standalone token/phrase and keeping auth-context errors on the auth path. Landed from contributor PR #31007 by @HOYALIM. Thanks @HOYALIM.
 - CLI/Cron: clarify `cron list` output by renaming `Agent` to `Agent ID` and adding a `Model` column for isolated agent-turn jobs. (#26259) Thanks @openperf.
