@@ -201,6 +201,7 @@ Docs: https://docs.openclaw.ai
 - Mattermost/slash commands: harden native slash-command callback token validation to use constant-time secret comparison, matching the existing interaction-token path.
 - Agents/scheduling: route delayed follow-up requests toward cron only when cron is actually available, while keeping background `exec`/`process` guidance scoped to work that starts now. (#60811) Thanks @vincentkoc.
 - Cron/security: reject unsafe custom `sessionTarget: "session:..."` IDs earlier during cron add, update, and execution so malformed custom session keys fail closed with clear errors.
+- Feishu/cards: replace the legacy `wide_screen_mode` schema 1.x config with schema 2.0 `width_mode: "fill"` in interactive approval, launcher, markdown, and structured card builders so Feishu card sends stop failing with parse-card errors while preserving wide-card rendering. (#53395) Thanks @drvoss
