CHANGELOG.md

@@ -11,6 +11,7 @@ Docs: https://docs.openclaw.ai
 - Discord: allow exec approval prompts to target channels or both DM+channel via `channels.discord.execApprovals.target`. (#16051) Thanks @leonnardo.
 - Sandbox: add `sandbox.browser.binds` to configure browser-container bind mounts separately from exec containers. (#16230) Thanks @seheepeak.
 - Discord: add debug logging for message routing decisions to improve `--debug` tracing. (#16202) Thanks @jayleekr.
+- Agents: add optional `messages.suppressToolErrors` config to hide non-mutating tool-failure warnings from user-facing chat while still surfacing mutating failures. (#16620) Thanks @vai-oro.
