# v5.0.4

## Enhancements

* Improve the dashboard listener startup log, the listener name is no longer spliced with port information,
  and the colon(:) is no longer displayed when IP is not specified. [#8480](https://github.com/emqx/emqx/pull/8480)
* Remove `/configs/listeners` API, use `/listeners/` instead. [#8485](https://github.com/emqx/emqx/pull/8485)
* Optimize performance of builtin database operations in processes with long message queue [#8439](https://github.com/emqx/emqx/pull/8439)
* Improve authentication tracing. [#8554](https://github.com/emqx/emqx/pull/8554)
* Standardize the '/listeners' and `/gateway/<name>/listeners` API fields.
  It will introduce some incompatible updates, see [#8571](https://github.com/emqx/emqx/pull/8571)
* Add option to perform GC on connection process after TLS/SSL handshake is performed. [#8637](https://github.com/emqx/emqx/pull/8637)

## Bug fixes

* The `data/configs/cluster-override.conf` is cleared to 0KB if `hocon_pp:do/2` failed [commits/71f64251](https://github.com/emqx/emqx/pull/8443/commits/71f642518a683cc91a32fd542aafaac6ef915720)
* Improve the health_check for webhooks.
  Prior to this change, the webhook only checks the connectivity of the TCP port using `gen_tcp:connect/2`, so
  if it's a HTTPs server, we didn't check if TLS handshake was successful.

* Avoid applying any ACL checks on superusers [#8452](https://github.com/emqx/emqx/pull/8452)

* Fix AuthN `cert_subject` and `cert_common_name` placeholder rendering failure. [#8531](https://github.com/emqx/emqx/pull/8531)

* GET '/rules' support for pagination and fuzzy search. [#8472](https://github.com/emqx/emqx/pull/8472)
  **‼️ Note** : The previous API only returns array: `[RuleObj1,RuleObj2]`, after updating, it will become
  `{"data": [RuleObj1,RuleObj2], "meta":{"count":2, "limit":100, "page":1}`,
  which will carry the paging meta information.
* Fix the issue that webhook leaks TCP connections. [ehttpc#34](https://github.com/emqx/ehttpc/pull/34), [#8580](https://github.com/emqx/emqx/pull/8580)
