* 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).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent): Properly return `200 OK` HTTP status code when importing data via [Pushgateway protocol](https://docs.victoriametrics.com/#how-to-import-data-in-prometheus-exposition-format) using [multitenant URL format](https://docs.victoriametrics.com/cluster-victoriametrics/#url-format). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3636) and [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7571).
