- Feishu: close WebSocket connections on monitor stop/abort so ghost connections no longer persist, preventing duplicate event processing and resource leaks across restart cycles. (#52844) Thanks @schumilin.

- Feishu: use the original message `create_time` instead of `Date.now()` for inbound timestamps so offline-retried messages carry the correct authoring time, preventing mis-targeted agent actions on stale instructions. (#52809) Thanks @schumilin.

- Plugins/SDK: thread `moduleUrl` through plugin-sdk alias resolution so user-installed plugins outside the openclaw directory (e.g. `~/.openclaw/extensions/`) correctly resolve `openclaw/plugin-sdk/*` subpath imports, and gate `plugin-sdk:check-exports` in `release:check`. (#54283) Thanks @xieyongliang.

### Breaking

- Telegram/outbound errors: preserve actionable 403 membership/block/kick details and treat `bot not a member` as a permanent delivery failure so Telegram sends stop retrying doomed chats. (#53635) Thanks @w-sss.

- Telegram/photos: preflight Telegram photo dimension and aspect-ratio rules, and fall back to document sends when image metadata is invalid or unavailable so photo uploads stop failing with `PHOTO_INVALID_DIMENSIONS`. (#52545) Thanks @hnshah.

- Slack/runtime defaults: trim Slack DM reply overhead, restore Codex auto transport, and tighten Slack/web-search runtime defaults around DM preview threading, cache scoping, warning dedupe, and explicit web-search opt-in. (#53957) Thanks @vincentkoc.
