@@ -49,6 +49,7 @@ Docs: https://docs.openclaw.ai
 - GitHub Copilot: refresh the model catalog from `${baseUrl}/models` so per-account entitlement and accurate context windows surface at runtime; static manifest catalog (now including `gpt-5.5`) remains the fallback when discovery is disabled or the API is unreachable.
 - Active Memory: support concrete `plugins.entries.active-memory.config.toolsAllow` recall tool names for custom memory plugins while keeping the built-in memory-core default on `memory_search`/`memory_get` and preserving `memory_recall` automatically for `plugins.slots.memory: "memory-lancedb"`.
 - Telegram: share the grammY API throttler across polling and ad hoc send clients for the same bot token, so visible draft previews and CLI sends use one quota gate. Thanks @anagnorisis2peripeteia.
+- Feishu: resolve group policy/tool context from the trusted chat target for group turns while keeping the speaker in `From`, so @mention replies do not drop the configured group id. Fixes #79457. Thanks @greyxiong.
 - Telegram/Feishu: honor configured per-agent and global `reasoningDefault` values when deciding whether channel reasoning previews should stream or stay hidden, addressing the preview-default part of #73182. Thanks @anagnorisis2peripeteia.
 - QQBot: mark recognized framework slash commands as text-command turns before reply dispatch so `/models`, `/status`, and `/new` responses stay visible in QQ Bot C2C conversations. Fixes #79310. Thanks @rollingshmily.
 - Docker: run the runtime image under `tini` so long-lived containers reap orphaned child processes and forward signals correctly. (#77885) Thanks @VintageAyu.
