 ## tip
 
+* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert): revert the default value of `-remoteWrite.maxQueueSize` from `1_000_000` to `100_000`. It was bumped in [v1.104.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.104.0), which increases memory usage and is not needed for most setups. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7471).
