CHANGELOG.md

@@ -94,6 +94,7 @@ Docs: https://docs.openclaw.ai
 - Cron: persist `delivered` state in cron job records so delivery failures remain visible in status and logs. (#19174) Thanks @simonemacario.
 - Config/Doctor: only repair the OAuth credentials directory when affected channels are configured, avoiding fresh-install noise.
 - Config/Channels: whitelist `channels.modelByChannel` in config validation and exclude it from plugin auto-enable channel detection so model overrides no longer trigger `unknown channel id` validation errors or bogus `modelByChannel` plugin enables. (#23412) Thanks @ProspectOre.
+- Config/Bindings: allow optional `bindings[].comment` in strict config validation so annotated binding entries no longer fail load. (#23458) Thanks @echoVic.
 - Usage/Pricing: correct MiniMax M2.5 pricing defaults to fix inflated cost reporting. (#22755) Thanks @miloudbelarebia.
 - Gateway/Daemon: verify gateway health after daemon restart.
 - Agents/UI text: stop rewriting normal assistant billing/payment language outside explicit error contexts. (#17834) Thanks @niceysam.
