* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): optimize auto-suggestion performance for metric names when the database contains big number of unique time series.
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): in the Select component, user-entered values are now preserved on blur if they match options in the list.
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): auto-suggestion triggers at any cursor position in the query input. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5864).
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): update error messages on the Query page for enhanced clarity. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6177).
* BUGFIX: [downsampling](https://docs.victoriametrics.com/#downsampling): skip unnecessary index lookups if downsampling wasn't set for ENT versions of VictoriaMetrics. Before, users of VictoriaMetrics ENT could have experience elevated CPU usage even if no downsampling was configured. The issue was introduced in [v1.100.0](https://docs.victoriametrics.com/changelog/#v11000).
* BUGFIX: [downsampling](https://docs.victoriametrics.com/#downsampling): properly populate downsampling metadata for data parts created by VictoriaMetrics ENT versions lower than v1.100.0. The bug could trigger the downsampling actions for parts that were downsampled already. This bug doesn't have any negative effect apart from spending extra CPU resources on the repeated downsampling. The issue was introduced in [v1.100.0](https://docs.victoriametrics.com/changelog/#v11000).
