@ -47,6 +47,7 @@ The following tip changes can be tested by building VictoriaMetrics components f
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly merge buckets with identical `le` values, but with different string representation of these values when calculating [histogram_quantile](https://docs.victoriametrics.com/MetricsQL.html#histogram_quantile) and [histogram_share](https://docs.victoriametrics.com/MetricsQL.html#histogram_share). For example, `http_request_duration_seconds_bucket{le="5"}` and `http_requests_duration_seconds_bucket{le="5.0"}`. Such buckets may be returned from distinct targets. Thanks to @647-coder for the [pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3225).
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): change severity level for log messages about failed attempts for sending data to remote storage from `error` to `warn`. The message for about all failed send attempts remains at `error` severity level.
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): fix panic if `vmagent` runs with `-clusterMode` command-line flag in [multitenant mode](https://docs.victoriametrics.com/vmalert.html#multitenancy). The issue has been introduced in [v1.82.0](https://docs.victoriametrics.com/CHANGELOG.html#v1820).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): do not show invalid error message in Kubernetes service discovery: `cannot parse WatchEvent json response: EOF`. The invalid error message has been appeared in [v1.82.0](https://docs.victoriametrics.com/CHANGELOG.html#v1820).
* BUGFIX: `vmselect`: expose missing metric `vm_cache_size_max_bytes{type="promql/rollupResult"}` . This metric is used for monitoring rollup cache usage with the query `vm_cache_size_bytes{type="promql/rollupResult"} / vm_cache_size_max_bytes{type="promql/rollupResult"}` in the same way as this is done for other cache types.

* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add experimental feature for displaying last 10 states of the rule (recording or alerting) evaluation. The state is available on the Rule page, which can be opened by clicking on `Details` link next to Rule's name on the `/groups` page.
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): allow using extra labels in annotiations. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3013).
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): allow configuring authorization params per list of targets in vmalert's notifier config for `static_configs`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2690).
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): allow using `{{$labels}}` for templating in command-line flag `-external.alert.source`. The change supposed to provide additional flexibility for generating alert's source link based on labels values.
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): allow using {% raw %}`{{$labels}}`{% endraw %} for templating in command-line flag `-external.alert.source`. The change supposed to provide additional flexibility for generating alert's source link based on labels values.
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add `vm_account_id` and `vm_project_id` labels to results of alerting and recording rules if `-clusterMode` is enabled. This improves [multitenant support in vmalert](https://docs.victoriametrics.com/vmalert.html#multitenancy).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): minimize the time needed for reading large responses from scrape targets in [stream parsing mode](https://docs.victoriametrics.com/vmagent.html#stream-parsing-mode). This should reduce scrape durations for such targets as [kube-state-metrics](https://github.com/kubernetes/kube-state-metrics) running in a big Kubernetes cluster.
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): add [sort_by_label_numeric](https://docs.victoriametrics.com/MetricsQL.html#sort_by_label_numeric) and [sort_by_label_numeric_desc](https://docs.victoriametrics.com/MetricsQL.html#sort_by_label_numeric_desc) functions for [numeric sort](https://www.gnu.org/software/coreutils/manual/html_node/Version-sort-is-not-the-same-as-numeric-sort.html) of input time series by the specified labels. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2938).
