**Update note 1:** this release drops support for direct upgrade from VictoriaMetrics versions prior [v1.28.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.28.0). Please upgrade to `v1.84.0`, wait until `finished round 2 of background conversion` line is emitted to log by single-node VictoriaMetrics or by `vmstorage`, and then upgrade to newer releases. **Update note 1:** this release drops support for direct upgrade from VictoriaMetrics versions prior [v1.28.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.28.0).

**Update note 2:** this release splits `type="indexdb"` metrics into `type="indexdb/inmemory"` and `type="indexdb/file"` metrics. This may break old dashboards and alerting rules, which contain [label filter](https://docs.victoriametrics.com/keyConcepts.html#filtering) on `{type="indexdb"}`. Such label filter must be substituted with `{type=~"indexdb.*"}`, so it matches `indexdb` from the previous releases and `indexdb/inmemory` + `indexdb/file` from new releases. It is recommended upgrading to the latest available dashboards and alerting rules mentioned in [these docs](https://docs.victoriametrics.com/#monitoring), since they already contain fixed label filters. **Update note 2:** this release splits `type="indexdb"` metrics into `type="indexdb/inmemory"` and `type="indexdb/file"` metrics.
