@ -42,6 +42,8 @@ See also [LTS releases](https://docs.victoriametrics.com/lts-releases/).
* 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.
* 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).
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert/): supported any status codes from the range 200-299 from alertmanager. Previously, only 200 status code considered a successful action. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6110).
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert/): avoid blocking `/api/v1/rules`, `/api/v1/alerts`, `/metrics` APIs when alerting rule uses template functions `query`, which could takes a while to execute. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6079).
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert/): fix links with anchors in vmalert's UI. Starting from [v1.99.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.99.0) vmalert could ignore anchors pointing to specific rule groups if `search` param was present in URL.
