 - ACP/resolver: fall through to thread-bound session resolution when an explicit `--session` token cannot be resolved while preserving the bad-token diagnostic when no thread binding exists, so Discord slash commands that auto-fill the current thread ID as the positional ACP target no longer return "Unable to resolve session target" errors. Fixes #66299. Thanks @hclsys, @kindomLee, and @martingarramon.
 - Agents/sessions: emit a terminal lifecycle backstop when embedded timeout/error turns return without `agent_end`, so Gateway sessions no longer stay stuck in `running` after failover surfaces a timeout. Fixes #74607. Thanks @millerc79.
 - Gateway/diagnostics: include stuck-session reason hints and recovery skip causes in warnings, so operators can tell whether a lane is waiting on active work, queued work, or stale bookkeeping. Thanks @vincentkoc.
+- Providers/DeepSeek: expose native DeepSeek V4 `xhigh` and `max` thinking levels through the provider `resolveThinkingProfile` hook so `/think xhigh|max` applies the intended effort instead of falling back to base levels. (#73008) Thanks @ai-hpc.
 - Agents/Codex: bound embedded-run cleanup, trajectory flushing, and command-lane task timeouts after runtime failures, so Discord and other chat sessions return to idle instead of staying stuck in processing. Thanks @vincentkoc.
 - Heartbeat/exec: consume successful metadata-only async exec completions silently so Telegram and other chat surfaces no longer ask users for missing command logs after `No session found`. Fixes #74595. Thanks @gkoch02.
 - Web fetch: add a documented `tools.web.fetch.ssrfPolicy.allowIpv6UniqueLocalRange` opt-in and thread it through cache keys and DNS/IP checks so trusted fake-IP proxy stacks using `fc00::/7` can work without broad private-network access. Fixes #74351. Thanks @jeffrey701.
