- Improve memory usage on core nodes when bootstrapping a replicant [#9236](https://github.com/emqx/emqx/pull/9236).
- Improve the stability of prometheus push_gateway and print error logs when POST fails [#9235](http://github.com/emqx/emqx/pull/9235).
- Now we can disable some internal prometheus metrics. Closing some metrics that are not cared about when the prometheus/stats API timeout ( the machine load is too high ). [#9222](https://github.com/emqx/emqx/pull/9222).
## Bug fixes
- Fix error log message when `mechanism` is missing in authentication config [#8924](https://github.com/emqx/emqx/pull/8924).
