## Enhancements
|
|
|
|
- The MongoDB library has been upgraded to support MongoDB version 5.1 and greater.
|
|
|
|
- Support proxy protocol of HAProxy for dashboard API [9803](https://github.com/emqx/emqx/pull/9803).
|
|
|
|
- Added Ubuntu 22.04 package release [#9831](https://github.com/emqx/emqx/pull/9831).
|
|
|
|
- Improve the integration of the `banned` and the `delayed` feature [#9790](https://github.com/emqx/emqx/pull/9790).
|
|
Now when publishing a delayed message will check first if its source client is banned, if true, this publish will be ignored.
|
|
|
|
- Security enhancement for retained messages [#9790](https://github.com/emqx/emqx/pull/9790).
|
|
The retained messages will not be published if the publisher client is banned.
|
|
|
|
- Now the corresponding session will be kicked when client is banned by `clientid` [#9904](https://github.com/emqx/emqx/pull/9904).
|
|
|
|
- Add more debug logs for authentication and ACL [#9943](https://github.com/emqx/emqx/pull/9943).
|
|
|
|
- Expose the stats `live_connections.count` and `live_connections.max` to Prometheus [#9929](https://github.com/emqx/emqx/pull/9929).
