CHANGELOG.md

@@ -68,6 +68,7 @@ Docs: https://docs.openclaw.ai
 - Feishu: pass `Buffer` directly to the Feishu SDK upload APIs instead of `Readable.from(...)` to avoid form-data upload failures. (#10345) Thanks @youngerstyle.
 - Feishu: trigger mention-gated group handling only when the bot itself is mentioned (not just any mention). (#11088) Thanks @openperf.
 - Feishu: probe status uses the resolved account context for multi-account credential checks. (#11233) Thanks @onevcat.
+- Feishu: add streaming card replies via Card Kit API and preserve `renderMode=auto` fallback behavior for plain-text responses. (#10379) Thanks @xzq-xu.
 - Feishu DocX: preserve top-level converted block order using `firstLevelBlockIds` when writing/appending documents. (#13994) Thanks @Cynosure159.
 - Feishu plugin packaging: remove `workspace:*` `openclaw` dependency from `extensions/feishu` and sync lockfile for install compatibility. (#14423) Thanks @jackcooper2015.
 - CLI/Wizard: exit with code 1 when `configure`, `agents add`, or interactive `onboard` wizards are canceled, so `set -e` automation stops correctly. (#14156) Thanks @0xRaini.
