# CHANGELOG
The following `tip` changes can be tested by building VictoriaMetrics components from the latest commits according to the following docs:
* [How to build single-node VictoriaMetrics](https://docs.victoriametrics.com/#how-to-build-from-sources)
* [How to build cluster version of VictoriaMetrics](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#building-from-sources)
* [How to build vmagent](https://docs.victoriametrics.com/vmagent.html#how-to-build-from-sources)
* [How to build vmalert](https://docs.victoriametrics.com/vmalert.html#how-to-build-from-sources)

Metrics of the latest version of VictoriaMetrics cluster are available for viewing at our
[sandbox](https://play-grafana.victoriametrics.com/d/oS7Bi_0Wz_vm/victoriametrics-cluster-vm).
The sandbox cluster installation runs under the constant load generated by
[prometheus-benchmark](https://github.com/VictoriaMetrics/prometheus-benchmark) and is used for testing latest releases.
See also [LTS releases](https://docs.victoriametrics.com/lts-releases/).
## tip
**vmalert's cmd-line flag `-datasource.lookback` was deprecated and will have no effect anymore. It will be completely removed in next releases. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5155) for more details.**
* SECURITY: upgrade Go builder from Go1.21.7 to Go1.22.1. See [the list of issues addressed in Go1.22.1](https://github.com/golang/go/issues?q=milestone%3AGo1.22.1+label%3ACherryPickApproved).
* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth/): allow discovering ip addresses for backend instances hidden behind a shared hostname, via `discover_backend_ips: true` option. This allows evenly spreading load among backend instances. See [these docs](https://docs.victoriametrics.com/vmauth/#discovering-backend-ips) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5707).
* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth/): allow routing incoming requests based on HTTP [query args](https://en.wikipedia.org/wiki/Query_string) via `src_query_args` option at `url_map`. See [these docs](https://docs.victoriametrics.com/vmauth/#generic-http-proxy-for-different-backends) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5878).
* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth/): allow routing incoming requests based on HTTP request headers via `src_headers` option at `url_map`. See [these docs](https://docs.victoriametrics.com/vmauth/#generic-http-proxy-for-different-backends).
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): reduce memory usage by up to 5x when aggregating over big number of unique [time series](https://docs.victoriametrics.com/keyconcepts/#time-series). The memory usage reduction is most visible when [stream deduplication](https://docs.victoriametrics.com/stream-aggregation/#deduplication) is enabled.
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): allow using `-streamAggr.dedupInterval` and `-remoteWrite.streamAggr.dedupInterval` command-line flags without the need to specify `-streamAggr.config` and `-remoteWrite.streamAggr.config`. See [these docs](https://docs.victoriametrics.com/stream-aggregation/#deduplication).
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add `-streamAggr.dropInputLabels` command-line flag, which can be used for dropping the listed labels from input samples before applying stream [de-duplication](https://docs.victoriametrics.com/stream-aggregation/#deduplication) and aggregation. This is faster and easier to use alternative to [input_relabel_configs](https://docs.victoriametrics.com/stream-aggregation/#relabeling). See [these docs](https://docs.victoriametrics.com/stream-aggregation/#dropping-unneeded-labels).
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add `dedup_interval` option, which allows configuring individual [deduplication intervals](https://docs.victoriametrics.com/stream-aggregation/#deduplication) per each [stream aggregation config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config).
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add `keep_metric_names` option, which can be set at [stream aggregation config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config) in order to keep the original metric names in the output aggregated samples instead of using [the default output metric naming scheme](https://docs.victoriametrics.com/stream-aggregation/#output-metric-names).
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): align the time of aggregated data flush to the specified aggregation `interval`. For example, if `interval` is set to `1m`, then the aggregated data will be flushed at the end of every minute. The alginment can be disabled by setting `no_align_flush_to_interval: true` option at [stream aggregation config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config). See [these docs](https://docs.victoriametrics.com/stream-aggregation/#flush-time-alignment) for details.
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add [unique_samples](https://docs.victoriametrics.com/stream-aggregation/#unique_samples) output, which can be used for calculating the number of unique sample values over the given `interval`.
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add [increase_prometheus](https://docs.victoriametrics.com/stream-aggregation/#increase_prometheus) and [total_prometheus](https://docs.victoriametrics.com/stream-aggregation/#total_prometheus) outputs, which can be used for `increase` and `total` aggregations when the first sample of every new [time series](https://docs.victoriametrics.com/keyconcepts/#time-series) must be ignored.
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): expose `vm_streamaggr_flush_timeouts_total` and `vm_streamaggr_dedup_flush_timeouts_total` [counters](https://docs.victoriametrics.com/keyconcepts/#counter) at [`/metrics` page](https://docs.victoriametrics.com/#monitoring), which can be used for detecting flush timeouts for stream aggregation states. Expose also `vm_streamaggr_flush_duration_seconds` and `vm_streamaggr_dedup_flush_duration_seconds` [histograms](https://docs.victoriametrics.com/keyconcepts/#histogram) for monitoring the real flush durations of stream aggregation states.
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): improve trace display for better visual separation of branches. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5926).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): use the provided `-remoteWrite.tlsServerName` as `Host` header in requests to `-remoteWrite.url`. This allows sending data to https remote storage by IP address instead of hostname. Thanks to @minor-fixes for initial idea and [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5802).
* FEATURE: optimize [`/api/v1/labels`](https://docs.victoriametrics.com/url-examples/#apiv1labels) and [`/api/v1/label/.../values`](https://docs.victoriametrics.com/url-examples/#apiv1labelvalues) when `match[]` filters contains metric name. For example, `/api/v1/label/instance/values?match[]=up` now works much faster than before. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5055).
* FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): support client-side TLS configuration for [native protocol](https://docs.victoriametrics.com/vmctl/#migrating-data-from-victoriametrics). See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5748). Thanks to @khushijain21 for the [pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5824).
* FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): support client-side TLS configuration for VictoriaMetrics destination specified via `--vm-*` cmd-line flags used in [InfluxDB](https://docs.victoriametrics.com/vmctl/#migrating-data-from-influxdb-1x), [Remote Read protocol](https://docs.victoriametrics.com/vmctl/#migrating-data-by-remote-read-protocol), [OpenTSDB](https://docs.victoriametrics.com/vmctl/#migrating-data-from-opentsdb), [Prometheus](https://docs.victoriametrics.com/vmctl/#migrating-data-from-prometheus) and [Promscale](https://docs.victoriametrics.com/vmctl/#migrating-data-from-promscale) migration modes.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly set `Host` header in requests to scrape targets if it is specified via [`headers` option](https://docs.victoriametrics.com/sd_configs/#http-api-client-options). Thanks to @fholzer for [the bugreport](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5969) and [the fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5970).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly set `Host` header in requests to scrape targets when [`server_name` option at `tls_config`](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#tls_config) is set. Previously the `Host` header was set incorrectly to the target hostname in this case.
* BUGFIX: do not drop `match[]` filter at [`/api/v1/series`](https://docs.victoriametrics.com/url-examples/#apiv1series) if `-search.ignoreExtraFiltersAtLabelsAPI` command-line flag is set, since missing `match[]` filter breaks `/api/v1/series` requests.
* BUGFIX: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): take into account sample timestamp during [deduplication](https://docs.victoriametrics.com/stream-aggregation/#deduplication). If multiple samples have the same timestamp on the configured deduplication interval, then the sample with the biggest value is kept. The logic is aligned with [`-dedup.minScrapeInterval`](https://docs.victoriametrics.com/#deduplication).
* BUGFIX: [vmctl](https://docs.victoriametrics.com/vmctl.html): properly parse TLS key and CA files for [InfluxDB](https://docs.victoriametrics.com/vmctl/#migrating-data-from-influxdb-1x) and [OpenTSDB](https://docs.victoriametrics.com/vmctl/#migrating-data-from-opentsdb) migration modes.
## [v1.99.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.99.0)
**12/03/2024: There's ongoing investigation of the issue [#5959](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5959) related to this release. Until the issue is addressed, please avoid updating to v1.99.0.**
Released at 2024-03-01
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): propagate [label filters](https://docs.victoriametrics.com/keyconcepts/#filtering) via all the [label manipulation functions](https://docs.victoriametrics.com/metricsql/#label-manipulation-functions). For example, `label_del(some_metric{job="foo"}, "instance") + other_metric{pod="bar"}` is now transformed to `label_del(some_metric{job="foo",pod="bar"}, "instance") + other_metric{job="foo",pod="bar"}`. This should reduce the amounts of time series processed during query execution.
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): add [count_values_over_time](https://docs.victoriametrics.com/MetricsQL.html#count_values_over_time) function. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5847).
* FEATURE: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and `vmstorage` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): expose `vm_last_partition_parts` [metrics](https://docs.victoriametrics.com/#monitoring), which show the number of [parts in the latest partition](https://docs.victoriametrics.com/#storage). These metrics may help debugging query performance slowdown related to the increased number of parts in the last partition, since usually all the ingested data is written to the last partition and all the queries are performed over the recently ingested data, e.g. the last partition.
* FEATURE: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and `vmstorage` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): expose `vm_snapshots` [metric](https://docs.victoriametrics.com/#monitoring), which shows the current number of snapshots created via [snapshot API](https://docs.victoriametrics.com/#how-to-work-with-snapshots).
* FEATURE: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): add `-search.ignoreExtraFiltersAtLabelsAPI` command-line flag, which can be used for reducing load on VictoriaMetrics when [/api/v1/labels](https://docs.victoriametrics.com/url-examples/#apiv1labels), [/api/v1/label/.../values](https://docs.victoriametrics.com/url-examples/#apiv1labelvalues) or [/api/v1/series](https://docs.victoriametrics.com/url-examples/#apiv1series) are queried with too broad [`extra_filters` or `extra_label`](https://docs.victoriametrics.com/#prometheus-querying-api-enhancements), which match many time series. See [these docs](https://docs.victoriametrics.com/#resource-usage-limits) for details.
* FEATURE: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): allow limiting CPU and RAM usage at [/api/v1/labels](https://docs.victoriametrics.com/url-examples/#apiv1labels), [/api/v1/label/.../values](https://docs.victoriametrics.com/url-examples/#apiv1labelvalues) and [/api/v1/series](https://docs.victoriametrics.com/url-examples/#apiv1series) on systems with [high churn rate](https://docs.victoriametrics.com/faq/#what-is-high-churn-rate) via `-search.maxLabelsAPIDuration` and `-search.maxLabelsAPISeries` command-line flags. See [these docs](https://docs.victoriametrics.com/#resource-usage-limits) for details.
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): support reading [Amazon CloudWatch](https://aws.amazon.com/cloudwatch/) metrics in [OpenTelemetry](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-metric-streams-formats-opentelemetry-100.html) format from [Amazon Data Firehose](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Metric-Streams.html).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add support for `client_id` option into [kuma_sd_configs](https://docs.victoriametrics.com/sd_configs/#kuma_sd_configs) in the same way as Prometheus does. See [this pull request](https://github.com/prometheus/prometheus/pull/13278).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add support for `enable_compression` option in [scrape_configs](https://docs.victoriametrics.com/sd_configs/#scrape_configs) in order to be compatible with Prometheus scrape configs. See [this pull request](https://github.com/prometheus/prometheus/pull/13166) and [this feature request](https://github.com/prometheus/prometheus/issues/12319). Note that `vmagent` was always supporting [`disable_compression` option](https://docs.victoriametrics.com/vmagent/#scrape_config-enhancements) before Prometheus added `enable_compression` option.
* FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): support client-side TLS configuration for [InfluxDB](https://docs.victoriametrics.com/vmctl/#migrating-data-from-influxdb-1x), [Remote Read protocol](https://docs.victoriametrics.com/vmctl/#migrating-data-by-remote-read-protocol) and [OpenTSDB](https://docs.victoriametrics.com/vmctl/#migrating-data-from-opentsdb). See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5748). Thanks to @khushijain21 for pull requests [1](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5783), [2](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5798), [3](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5797).
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): preserve [`WITH` templates](https://play.victoriametrics.com/select/accounting/1/6a716b0f-38bc-4856-90ce-448fd713e3fe/expand-with-exprs) when clicking the `prettify query` button at the right side of query input field. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5383).
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): allow filling gaps on graphs with interpolated lines as Grafana does. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5152) and [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5862).
* FEATURE: [vmalert](https://docs.victoriametrics.com/#vmalert): support filtering by group, rule or labels in [vmalert's UI](https://docs.victoriametrics.com/vmalert/#web) for `/groups` and `/alerts` pages. See [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5791) by @victoramsantos.
* FEATURE: [docker-compose](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/master/deployment/docker#docker-compose-environment-for-victoriametrics): create a separate [docker-compose environment](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/deployment/docker/docker-compose-victorialogs.yml) for VictoriaLogs installation, including fluentbit and [VictoriaLogs Grafana datasource](https://github.com/VictoriaMetrics/victorialogs-datasource). See [these docs](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/master/deployment/docker#victorialogs-server) for details.
* FEATURE: [vmbackupmanager](https://docs.victoriametrics.com/vmbackupmanager/): wait for up 30 seconds before making a [snapshot](https://docs.victoriametrics.com/#how-to-work-with-snapshots) for backup if `vmstorage` is temporarily unavailalbe. This should prevent from `vmbackupmanager` termination in this case. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5859).
* BUGFIX: downgrade Go builder from `1.22.0` to `1.21.7`, since `1.22.0` contains [the bug](https://github.com/golang/go/issues/65705), which can lead to deadlocked HTTP connections to remote storage systems, scrape targets and service discovery endpoints at [vmagent](https://docs.victoriametrics.com/vmagent/). This may result in incorrect service discovery, target scraping and failed sending samples to remote storage.
* BUGFIX: all VictoriaMetrics components: return back periodic closing of incoming connections to `-httpListenAddr` every 2 minutes, which was disabled in [v1.98.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.98.0) when addressing [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1304#issuecomment-1636997037). See [this comment](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1304#issuecomment-1961891450) for details on why the periodic closing of incoming connections has been returned back.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): accept OpenTelemetry data at `/opentelemetry/v1/metrics`, since the `/v1/metrics` suffix is hardcoded at [OpenTelemetry protocol specification](https://opentelemetry.io/docs/specs/otlp/#otlphttp-request).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): fix possible deadlock when [sharding among remote storages](https://docs.victoriametrics.com/vmagent/#sharding-among-remote-storages) is enabled with `-remoteWrite.shardByURL` command-line flag. Thanks to @penguinlav for [the fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5834) for [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5833).
* BUGFIX: fix the misleading error `0ms is out of allowed range [0 ...` when passing `step=0` to [/api/v1/query](https://docs.victoriametrics.com/keyconcepts/#instant-query) or [/api/v1/query_range](https://docs.victoriametrics.com/keyconcepts/#range-query). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5795).
* BUGFIX: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): fixed floating-point error when parsing time in RFC3339 format. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5801) for details.
* BUGFIX: [vmalert](https://docs.victoriametrics.com/#vmalert): consistently sort groups by name and filename on `/groups` page in UI. This should prevent non-deterministic sorting for groups with identical names.
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix Popper display issues. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5842).
* BUGFIX: [vmselect](https://docs.victoriametrics.com/): format time with milliseconds precision when `__timestamp__:rfc3339` is specified for [/api/v1/export/csv](https://docs.victoriametrics.com/#how-to-export-csv-data) API response. See this [issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5837) for details.
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly construct the destination label in [label_join](https://docs.victoriametrics.com/metricsql/#label_join) if it is used as source label. See this [issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5881) for details.
## [v1.98.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.98.0)
Released at 2024-02-14
* SECURITY: upgrade Go builder from Go1.21.6 to Go1.22.0. See [the list of issues addressed in Go1.21.7](https://github.com/golang/go/issues?q=milestone%3AGo1.21.7+label%3ACherryPickApproved),
plus [the changelog for Go1.22.0](https://go.dev/doc/go1.22).
* FEATURE: all VictoriaMetrics components: add support for TLS client certificate verification at `-httpListenAddr` (aka [mTLS](https://en.wikipedia.org/wiki/Mutual_authentication)). See [these docs](https://docs.victoriametrics.com/#mtls-protection) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5458).
* FEATURE: all VictoriaMetrics components: add support for accepting http requests over multiple distinct TCP addresses. This can be done by starting VictoriaMetrics component with multiple `-httpListenAddr` command-line flags. For example, `./victoria-metrics -httpListenAddr=some-host:12345 -httpListenAddr=localhost:8428` starts VictoriaMetrics, which accepts incoming http requests at both `some-host:12345` and `localhost:8428`. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1470).
* FEATURE: all VictoriaMetrics components: add support for empty command-line flag values in short array notation. For example, `-remoteWrite.sendTimeout=',20s,'` specifies three `-remoteWrite.sendTimeout` values - the first one and the last one have default values (`30s` in this case), while the second one is set to `20s`.
* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth.html): add support for [mTLS](https://en.wikipedia.org/wiki/Mutual_authentication)-based request routing to different backends depending on the subject of the TLS certificate provided by the client. See [these docs](https://docs.victoriametrics.com/vmauth.html#mtls-based-request-routing) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1547).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html) and [single-node VictoriaMetrics](https://docs.victoriametrics.com): add support for data ingestion via [DataDog lambda extension](https://docs.datadoghq.com/serverless/libraries_integrations/extension/) aka `/api/beta/sketches` endpoint. See [these docs](https://docs.victoriametrics.com/#how-to-send-data-from-datadog-agent) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3091). Thanks to @AndrewChubatiuk for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5584).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add `-remoteWrite.tlsHandshakeTimeout` command-line flag for tuning the timeout needed for establishing TLS connections to `-remoteWrite.url`. Bigger tls handshake timeouts should reduce the probability of `http: TLS handshake error from ...: EOF` errors at the remote storage side under high load. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1699).
* FEATURE: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): add `-disableReroutingOnUnavailable` command-line flag to `vminsert`, which can be used for reducing resource usage spikes at `vmstorage` nodes during rolling restart. See [these docs](https://docs.victoriametrics.com/cluster-victoriametrics/#improving-re-routing-performance-during-restart). Thanks to @Muxa1L for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5713).
* FEATURE: add `-search.resetRollupResultCacheOnStartup` command-line flag for resetting [query cache](https://docs.victoriametrics.com/#rollup-result-cache) on startup. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/834).
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): propagate label filters across [label_set](https://docs.victoriametrics.com/MetricsQL.html#label_set) and [alias](https://docs.victoriametrics.com/MetricsQL.html#alias) functions. For example, `label_set(q1, "a", "b") + q2{c="d"}` is automatically transformed to `label_set(q1{c="d"}, "a", "b") + q2{a="b",c="d"}` now. This should improve performance for such queries. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1827#issuecomment-1654095358).
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): add [sum_eq_over_time](https://docs.victoriametrics.com/MetricsQL.html#sum_eq_over_time), [sum_gt_over_time](https://docs.victoriametrics.com/MetricsQL.html#sum_gt_over_time) and [sum_le_over_time](https://docs.victoriametrics.com/MetricsQL.html#sum_le_over_time) functions. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4641).
* FEATURE: [dashboards/vmagent](https://grafana.com/grafana/dashboards/12683): add `Targets scraped/s` stat panel showing the number of targets scraped by the vmagent per-second.
* FEATURE: [dashboards/all](https://grafana.com/orgs/victoriametrics): add new panel `CPU spent on GC`. It should help identifying cases when too much CPU is spent on garbage collection, and advice users on how this can be addressed.
* FEATURE: [vmalert](https://docs.victoriametrics.com/#vmalert): support [filtering](https://prometheus.io/docs/prometheus/2.49/querying/api/#rules) for `/api/v1/rules` API. See [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5749) by @victoramsantos.
* FEATURE: [vmbackup](https://docs.victoriametrics.com/vmbackup.html): support client-side TLS configuration for creating and deleting snapshots via `-snapshot.tls*` cmd-line flags. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5724). Thanks to @khushijain21 for the [pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5738).
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add a time picker to the "Logs Explorer" page. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5673).
* BUGFIX: all VictoriaMetrics components: do not close connections to `-httpListenAddr` every 2 minutes. This behavior didn't help spreading load among multiple backend servers behind load-balancing TCP proxy. Instead, it could lead to hard-to-debug issues like [this one](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1304#issuecomment-1636997037). If you still need periodically closing client connections because of some reason, then pass the desired timeout to `-http.connTimeout` command-line flag.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): reduce CPU usage when `-promscrape.dropOriginalLabels` command-line flag is set. This issue has been introduced in [v1.96.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.96.0) when addressing [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5389).
* BUGFIX: [vmauth](https://docs.victoriametrics.com/vmauth.html): properly release memory during config reload. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4690).
* BUGFIX: [vmauth](https://docs.victoriametrics.com/vmauth.html): properly expose `vmauth_unauthorized_user_concurrent_requests_capacity`, `vmauth_unauthorized_user_concurrent_requests_current`, `vmauth_user_concurrent_requests_capacity` and `vmauth_user_concurrent_requests_current` [metrics](https://docs.victoriametrics.com/vmauth.html#monitoring) after [config reload](https://docs.victoriametrics.com/vmauth.html#config-reload). Previously these metrics didn't work after config reload.
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly propagate [label filters](https://docs.victoriametrics.com/keyconcepts/#filtering) from multiple arguments passed to [aggregate functions](https://docs.victoriametrics.com/metricsql/#aggregate-functions). For example, `sum({job="foo"}, {job="bar"}) by (job) + a` was improperly optimized to `sum({job="foo"}, {job="bar"}) by (job) + a{job="foo"}` before being executed. This could lead to unexpected results. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5604).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly handle precision errors when calculating [changes](https://docs.victoriametrics.com/metricsql/#changes), [changes_prometheus](https://docs.victoriametrics.com/metricsql/#changes_prometheus), [increases_over_time](https://docs.victoriametrics.com/metricsql/#increases_over_time) and [resets](https://docs.victoriametrics.com/metricsql/#resets) functions. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/767).
* BUGFIX: all VictoriaMetrics components: consistently return 200 http status code from [`/-/reload` endpoint](https://docs.victoriametrics.com/vmagent/#configuration-update). Previously [single-node VictoriaMetrics](https://docs.victoriametrics.com/) was returning 204 http status code. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5774).
* BUGFIX: properly store [staleness markers](https://docs.victoriametrics.com/vmagent/#prometheus-staleness-markers) for [self-scraped metrics](https://docs.victoriametrics.com/#monitoring) on single-node VictoriaMetrics shutdown. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/943).
* BUGFIX: prevent from possible `too big indexBlockSize` panic when samples with too long label values (~64Kb) are ingested into VictoriaMetrics.
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix the graph dragging for Firefox and Safari. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5764).
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix handling invalid timezone. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5732).
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix the bug where the select does not open. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5728).
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): clear entered text in select after selecting a value. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5727).
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): improve the operation of the context for autocomplete. See [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5736), [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5737) and [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5739) issues.
* BUGFIX: [dashboards](https://grafana.com/orgs/victoriametrics): update `Storage full ETA` panels for Single-node and Cluster dashboards to prevent them from showing negative or blank results caused by increase of deduplicated samples. Deduplicated samples were part of the expression to provide a better estimate for disk usage, but due to sporadic nature of [deduplication](https://docs.victoriametrics.com/#deduplication) in VictoriaMetrics it rather produced skewed results. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5747).
* BUGFIX: [vmalert](https://docs.victoriametrics.com/#vmalert): reduce memory usage for ENT version of vmalert for configurations with high number of groups with enabled multitenancy.
## [v1.97.3](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.97.3)
Released at 2024-03-01
**v1.97.x is a line of [LTS releases](https://docs.victoriametrics.com/lts-releases/). It contains important up-to-date bugfixes for [VictoriaMetrics enterprise](https://docs.victoriametrics.com/enterprise.html).
All these fixes are also included in [the latest community release](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest).
The v1.97.x line will be supported for at least 12 months since [v1.97.0](https://docs.victoriametrics.com/CHANGELOG.html#v1970) release**
* BUGFIX: downgrade Go builder from `1.22.0` to `1.21.7`, since `1.22.0` contains [the bug](https://github.com/golang/go/issues/65705), which can lead to deadlocked HTTP connections to remote storage systems, scrape targets and service discovery endpoints at [vmagent](https://docs.victoriametrics.com/vmagent/). This may result in incorrect service discovery, target scraping and failed sending samples to remote storage.
* BUGFIX: take into account `-search.maxUniqueTimeseries` limit at [/api/v1/labels](https://docs.victoriametrics.com/url-examples/#apiv1labels), [/api/v1/label/.../values](https://docs.victoriametrics.com/url-examples/#apiv1labelvalues) and [/api/v1/series](https://docs.victoriametrics.com/url-examples/#apiv1series). This limit was ignored at these endpoints starting from [v1.97.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.97.0) when trying to address [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5055). It has been appeared that this can result in high CPU usage when heaviweight queries hit these endpoints. This can prevent from executing lightweight queries to these endpoints. It is better to return `limit exceeded` error to heavyweight queries instead of burning CPU.
* BUGFIX: all VictoriaMetrics components: return back periodic closing of incoming connections to `-httpListenAddr` every 2 minutes, which was disabled in [v1.97.2](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.97.2) when addressing [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1304#issuecomment-1636997037). See [this comment](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1304#issuecomment-1961891450) for details on why the periodic closing of incoming connections has been returned back.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): accept OpenTelemetry data at `/opentelemetry/v1/metrics`, since the `/v1/metrics` suffix is hardcoded at [OpenTelemetry protocol specification](https://opentelemetry.io/docs/specs/otlp/#otlphttp-request).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): fix possible deadlock when [sharding among remote storages](https://docs.victoriametrics.com/vmagent/#sharding-among-remote-storages) is enabled with `-remoteWrite.shardByURL` command-line flag. Thanks to @penguinlav for [the fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5834) for [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5833).
* BUGFIX: fix the misleading error `0ms is out of allowed range [0 ...` when passing `step=0` to [/api/v1/query](https://docs.victoriametrics.com/keyconcepts/#instant-query)
or [/api/v1/query_range](https://docs.victoriametrics.com/keyconcepts/#range-query). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5795).
* BUGFIX: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): fixed floating-point error when parsing time in RFC3339 format. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5801) for details.
* BUGFIX: [vmalert](https://docs.victoriametrics.com/#vmalert): consistently sort groups by name and filename on `/groups` page in UI. This should prevent non-deterministic sorting for groups with identical names.
* BUGFIX: [vmalert](https://docs.victoriametrics.com/#vmalert): reduce memory usage for ENT version of vmalert for configurations with high number of groups with enabled multitenancy.
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly construct the destination label in [label_join](https://docs.victoriametrics.com/metricsql/#label_join) if it is used as source label. See this [issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5881) for details.

The v1.97.x line will be supported for at least 12 months since [v1.97.0](https://docs.victoriametrics.com/CHANGELOG.html#v1970) release**
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add support for `username_file` option at `basic_auth` section in [`scrape_configs`](https://docs.victoriametrics.com/sd_configs/#http-api-client-options). See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5511). Thanks to @wasim-nihal for [the initial implementation](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5720).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): fix the increased CPU usage when sending the data to remote storage. The issue has been introduced in [v1.97.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.97.0).
* BUGFIX: fix `runtime error: slice bounds out of range` panic, which can occur during query execution. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5733). The bug has been introduced in `v1.97.0`.
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly handle `avg_over_time({some_filter}[d]) keep_metric_names` queries, where [`some_filter`](https://docs.victoriametrics.com/keyconcepts/#filtering) matches multiple time series with multiple names, while `d` is bigger or equal to `3h`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5556).

See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3154) and [these docs](https://docs.victoriametrics.com/sd_configs.html#hetzner_sd_configs).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add support for [DataDog v2 data ingestion protocol](https://docs.datadoghq.com/api/latest/metrics/#submit-metrics). See [these docs](https://docs.victoriametrics.com/#how-to-send-data-from-datadog-agent) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4451).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): reduce initial memory usage when scraping targets, which return huge responses (for example, [kube-state-metrics](https://github.com/kubernetes/kube-state-metrics) in large Kubernetes cluster may return 100MB+ responses), without the need to explicitly enable [stream parsing mode](https://docs.victoriametrics.com/vmagent/#stream-parsing-mode). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5567).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): expose ability to set OAuth2 endpoint parameters per each `-remoteWrite.url` via the command-line flag `-remoteWrite.oauth2.endpointParams`. See [these docs](https://docs.victoriametrics.com/vmagent.html#advanced-usage). Thanks to @mhill-holoplot for the [pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5427).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add ability to set `attach_metadata.node=true` option for all the [`kubernetes_sd_configs`](https://docs.victoriametrics.com/sd_configs.html#kubernetes_sd_configs) defined at [`-promscrape.config`](https://docs.victoriametrics.com/vmagent.html#quick-start) via `-promscrape.kubernetes.attachNodeMetadataAll` command-line flag. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4640). Thanks to @wasim-nihal for [the initial implementation](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5593).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): do not send unfinished [aggregation state](https://docs.victoriametrics.com/stream-aggregation.html) on shutdown or [hot config reload](https://docs.victoriametrics.com/stream-aggregation.html#configuration-update) by default, as it tend to produce unexpected anomalies with lower values. The old behavior can be restored by specifying `flush_on_shutdown: true` setting in streaming aggregation config. See more details [here](https://docs.victoriametrics.com/stream-aggregation.html#aggregation-outputs).
* FEATURE: [streaming aggregation](https://docs.victoriametrics.com/stream-aggregation.html): expand `%{ENV_VAR}` placeholders in config files with the corresponding environment variable values.
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmagent.html): expose ability to set OAuth2 endpoint parameters via the following command-line flags:
- `-datasource.oauth2.endpointParams` for `-datasource.url`
- `-notifier.oauth2.endpointParams` for `-notifier.url`
- `-remoteRead.oauth2.endpointParams` for `-remoteRead.url`
- `-remoteWrite.oauth2.endpointParams` for `-remoteWrite.url`
* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth.html): add ability to proxy incoming requests to different backends based on the requested host via `src_hosts` option at `url_map`. See [these docs](https://docs.victoriametrics.com/vmauth.html#generic-http-proxy-for-different-backends).
* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth.html): expose `vmauth_user_request_backend_errors_total` and `vmauth_unauthorized_user_request_backend_errors_total` [metrics](https://docs.victoriametrics.com/vmauth.html#monitoring), which track the number of failed requests because of backend errors. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5565).
* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth.html): add an ability to specify additional labels for [per-user metrics](https://docs.victoriametrics.com/vmauth.html#monitoring) via `metric_labels` section. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5565).
* FEATURE: all VictoriaMetrics components: break HTTP client connection if an error occurs after the server at `-httpListenAddr` already sent response status code. Previously such an error couldn't be detected at client side. Now the client will get an error about invalid chunked response. The error message is simultaneously written to the server log and in the last line of the response. This should help detecting errors when migrating data between VictoriaMetrics instances by [vmctl](https://docs.victoriametrics.com/vmctl.html). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5645).
* FEATURE: all VictoriaMetrics components: add ability to specify arbitrary HTTP headers to send with every request to `-pushmetrics.url`. See [`push metrics` docs](https://docs.victoriametrics.com/#push-metrics).
* FEATURE: all VictoriaMetrics components: add `-metrics.exposeMetadata` command-line flag, which allows displaying `TYPE` and `HELP` metadata at `/metrics` page exposed at `-httpListenAddr`. This may be needed when the `/metrics` page is scraped by collector, which requires the `TYPE` and `HELP` metadata such as [Google Cloud Managed Prometheus](https://cloud.google.com/stackdriver/docs/managed-prometheus/troubleshooting#missing-metric-type).
* FEATURE: all VictoriaMetrics components: add ability to dynamically re-read auth keys and passwords from files and urls when using `file:///path/to/file` or `http://host/path` syntax for the following command-line flags: `-configAuthKey`, `-deleteAuthKey`, `-flagsAuthKey`, `-forceMergeAuthKey`, `-forceFlushAuthKey`, `-httpAuth.password`, `-metricsAuthKey`, `-pprofAuthKey`, `-reloadAuthKey`, `-search.resetCacheAuthKey`, `-snapshotAuthKey`. For example, `-httpAuth.password=file:///path/to/password`. See [these docs](https://docs.victoriametrics.com/#security) for details.
* FEATURE: [dashboards/cluster](https://grafana.com/grafana/dashboards/11176): add panels for detailed visualization of traffic usage between vmstorage, vminsert, vmselect components and their clients. New panels are available in the rows dedicated to specific components.
* FEATURE: [dashboards/cluster](https://grafana.com/grafana/dashboards/11176): update "Slow Queries" panel to show percentage of the slow queries to the total number of read queries served by vmselect. The percentage value should make it more clear for users whether there is a service degradation.
* FEATURE: [dashboards/single](https://grafana.com/grafana/dashboards/10229): change dashboard title from `VictoriaMetrics` to `VictoriaMetrics - single-node`. The new title should provide better understanding of this dashboard purpose.
* FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): rename cmd-line flag `vm-native-disable-retries` to `vm-native-disable-per-metric-migration` to better reflect its meaning.
* FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): add `-vm-native-src-insecure-skip-verify` and `-vm-native-dst-insecure-skip-verify` command-line flags for native protocol. It can be used for skipping TLS certificate verification when connecting to the source or destination addresses.
* FEATURE: [Alerting rules for VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/master/deployment/docker#alerts): add `job` label to `DiskRunsOutOfSpace` alerting rule, so it is easier to understand to which installation the triggered instance belongs.
* FEATURE: `vmstorage`: add tenant identifier for log messages regarding dropping excessive labels due to limits defined by `-maxLabelsPerTimeseries` or `-maxLabelValueLen` command-line flags. Previously, it was hard to understand to which tenant the dropped labels belong.
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add the ability to export and import query reports:
- add a `Query Analyzer` page that allows you to build graphs from `JSON` data containing the results of executing a query request.
- add an `Export query` button to the graph that saves the result of executing the query in `JSON`. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5497).
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add `-vmui.defaultTimezone` flag to set a default timezone. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5375) and [these docs](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/master/app/vmui#timezone-configuration).
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): include UTC in the timezone selection dropdown for standardized time referencing. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5375).
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add the ability to expand/collapse all tracing entries and download tracing data in .json format. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5677).
* FEATURE: add [VictoriaMetrics datasource](https://github.com/VictoriaMetrics/grafana-datasource) to docker compose environment. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5363).
* BUGFIX: properly return the list of matching label names and label values from [`/api/v1/labels`](https://docs.victoriametrics.com/url-examples.html#apiv1labels) and [`/api/v1/label/.../values`](https://docs.victoriametrics.com/url-examples.html#apiv1labelvalues) when the database contains more than `-search.maxUniqueTimeseries` unique [time series](https://docs.victoriametrics.com/keyConcepts.html#time-series) on the selected time range. Previously VictoriaMetrics could return `the number of matching timeseries exceeds ...` error in this case. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5055).
* BUGFIX: properly return errors from [export APIs](https://docs.victoriametrics.com/#how-to-export-time-series). Previously these errors were silently suppressed. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5649).
* BUGFIX: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): properly return full results when `-search.skipSlowReplicas` command-line flag is passed to `vmselect` and when [vmstorage groups](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#vmstorage-groups-at-vmselect) are in use. Previously partial results could be returned in this case.
* BUGFIX: `vminsert`: properly accept samples via [OpenTelemetry data ingestion protocol](https://docs.victoriametrics.com/#sending-data-via-opentelemetry) when these samples have no [resource attributes](https://opentelemetry.io/docs/instrumentation/go/resources/). Previously such samples were silently skipped.
* BUGFIX: `vmstorage`: added missing `-inmemoryDataFlushInterval` command-line flag, which was missing in [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html) after implementing [this feature](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3337) in [v1.85.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.85.0).
* BUGFIX: `vmstorage`: properly expire `storage/prefetchedMetricIDs` cache. Previously this cache was never expired, so it could grow big under [high churn rate](https://docs.victoriametrics.com/FAQ.html#what-is-high-churn-rate). This could result in increasing CPU load over time.
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): check `-external.url` schema when starting vmalert, must be `http` or `https`. Before, alertmanager could reject alert notifications if `-external.url` contained no or wrong schema.
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): automatically add `exported_` prefix for original evaluation result label if it's conflicted with external or reserved one, previously it was overridden. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5161).
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): autogenerate `ALERTS_FOR_STATE` time series for alerting rules with `for: 0`. Previously, `ALERTS_FOR_STATE` was generated only for alerts with `for > 0`. The change aligns with Prometheus behavior. See more details in [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5648).
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): fix data race during hot-config reload. The result of the race could cause all rules from updated group to fail with `context cancelled` error.
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): consistently sort results for `q1 or q2` query, so they do not change colors with each refresh in Grafana. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5393).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly return results from [bottomk](https://docs.victoriametrics.com/MetricsQL.html#bottomk) and `bottomk_*()` functions when some of these results contain NaN values. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5506). Thanks to @xiaozongyang for [the fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5509).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly handle queries, which wrap [rollup functions](https://docs.victoriametrics.com/MetricsQL.html#rollup-functions) with multiple arguments without explicitly specified lookbehind window in square brackets into [aggregate functions](https://docs.victoriametrics.com/MetricsQL.html#aggregate-functions). For example, `sum(quantile_over_time(0.5, process_resident_memory_bytes))` was resulting to `expecting at least 2 args to ...; got 1 args` error. Thanks to @atykhyy for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5414).
* BUGFIX: [vmctl](https://docs.victoriametrics.com/vmctl.html): retry on import errors in `vm-native` mode. Before, retries happened only on writes into a network connection between source and destination. But errors returned by server after all the data was transmitted were logged, but not retried.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly assume role with [AWS IRSA authorization](https://docs.aws.amazon.com/eks/latest/userguide/iam-roles-for-service-accounts.html). Previously role chaining was not supported. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3822) for details.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): exit if there is config syntax error in [`scrape_config_files`](https://docs.victoriametrics.com/vmagent.html#loading-scrape-configs-from-multiple-files) when `-promscrape.config.strictParse=true`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5508).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly discover targets for `role: endpoints` and `role: endpointslice` in [kubernetes_sd_configs](https://docs.victoriametrics.com/sd_configs.html#kubernetes_sd_configs). Previously some `endpoints` and `endpointslice` targets could be left undiscovered or some targets could have missing `__meta_*` labels when performing service discovery in busy Kubernetes clusters with large number of pods. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5557).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): respect explicitly set `series_limit: 0` in [scrape_config](https://docs.victoriametrics.com/sd_configs.html#scrape_configs). This allows removing [`series_limit` restriction](https://docs.victoriametrics.com/vmagent.html#cardinality-limiter) on a per-`scrape_config` basis when global limit is set via `-promscrape.seriesLimitPerTarget`. Previously, `0` value was ignored in favor of `-promscrape.seriesLimitPerTarget`.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): do not discover scrape targets for already terminated pods and containers in [`kubernetes_sd_configs`](https://docs.victoriametrics.com/sd_configs.html#kubernetes_sd_configs). Such pods and containers cannot be scraped and cannot resurrect, so there is no sense in generating scrape targets for them.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly follow redirects to another hostnames when `follow_redirects: true` option is set in [`scrape_configs`](https://docs.victoriametrics.com/sd_configs/#http-api-client-options) while [stream parsing mode](https://docs.victoriametrics.com/vmagent/#stream-parsing-mode) is disabled. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1945) and [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4931).
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix a link for the statistic inaccuracy explanation in the cardinality explorer tool. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5460).
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix the display of autocomplete results and cache the results. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5472) and [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5470).
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): send `step` param for instant queries. The change reverts [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3896) due to reasons explained in [this comment](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3896#issuecomment-1896704401).
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix the `Enter` key press issue in the `Query` field when using autocomplete. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5667).
* BUGFIX: all: fix potential panic during components shutdown when [metrics push](https://docs.victoriametrics.com/#push-metrics) is configured. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5548). Thanks to @zhdd99 for the [pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5549).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly process queries with too big lookbehind window such as `foo[100y]`. Previously, such queries could return empty responses even if `foo` is present in database. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5553).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly handle possible negative results caused by float operations precision error in rollup functions like rate() or increase(). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5571).
* BUGFIX: `vmselect`: vmsingle/vmselect returns http status 429 (TooManyRequests) instead of 503 (ServiceUnavailable) when max concurrent requests limit is reached.
* BUGFIX: `vmselect`: set proper timestamps in [instant query](https://docs.victoriametrics.com/keyconcepts/#instant-query) results if the query contains [rollup functions](https://docs.victoriametrics.com/metricsql/#rollup-functions) with lookbehind windows in square brackets exceeding 3 hours. For example, `sum(avg_over_time(up[24h]))`. This bug has been introduced in [v1.95.0](https://docs.victoriametrics.com/changelog_2023/#v1950). See [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5659) and [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5730) issues.

## [v1.93.13](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.93.13)
Released at 2024-03-01
**v1.93.x is a line of [LTS releases](https://docs.victoriametrics.com/lts-releases/). It contains important up-to-date bugfixes.
The v1.93.x line will be supported for at least 12 months since [v1.93.0](https://docs.victoriametrics.com/CHANGELOG.html#v1930) release**
* BUGFIX: downgrade Go builder from `1.22.0` to `1.21.7`, since `1.22.0` contains [the bug](https://github.com/golang/go/issues/65705), which can lead to deadlocked HTTP connections to remote storage systems, scrape targets and service discovery endpoints at [vmagent](https://docs.victoriametrics.com/vmagent/). This may result in incorrect service discovery, target scraping and failed sending samples to remote storage.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): accept OpenTelemetry data at `/opentelemetry/v1/metrics`, since the `/v1/metrics` suffix is hardcoded at [OpenTelemetry protocol specification](https://opentelemetry.io/docs/specs/otlp/#otlphttp-request).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): fix possible deadlock when [sharding among remote storages](https://docs.victoriametrics.com/vmagent/#sharding-among-remote-storages) is enabled with `-remoteWrite.shardByURL` command-line flag. Thanks to @penguinlav for [the fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5834) for [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5833).
* BUGFIX: fix the misleading error `0ms is out of allowed range [0 ...` when passing `step=0` to [/api/v1/query](https://docs.victoriametrics.com/keyconcepts/#instant-query)
or [/api/v1/query_range](https://docs.victoriametrics.com/keyconcepts/#range-query). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5795).
* BUGFIX: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): fixed floating-point error when parsing time in RFC3339 format. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5801) for details.
* BUGFIX: [vmalert](https://docs.victoriametrics.com/#vmalert): consistently sort groups by name and filename on `/groups` page in UI. This should prevent non-deterministic sorting for groups with identical names.
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly construct the destination label in [label_join](https://docs.victoriametrics.com/metricsql/#label_join) if it is used as source label. See this [issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5881) for details.
## [v1.93.12](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.93.12)

The v1.93.x line will be supported for at least 12 months since [v1.93.0](https://docs.victoriametrics.com/CHANGELOG.html#v1930) release**
* SECURITY: upgrade Go builder from Go1.21.6 to Go1.22.0. See [the list of issues addressed in Go1.21.7](https://github.com/golang/go/issues?q=milestone%3AGo1.21.7+label%3ACherryPickApproved), plus [the changelog for Go1.22.0](https://go.dev/doc/go1.22).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly propagate [label filters](https://docs.victoriametrics.com/keyconcepts/#filtering) from multiple arguments passed to [aggregate functions](https://docs.victoriametrics.com/metricsql/#aggregate-functions). For example, `sum({job="foo"}, {job="bar"}) by (job) + a` was improperly optimized to `sum({job="foo"}, {job="bar"}) by (job) + a{job="foo"}` before being executed. This could lead to unexpected results. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5604).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly handle precision errors when calculating [changes](https://docs.victoriametrics.com/metricsql/#changes), [changes_prometheus](https://docs.victoriametrics.com/metricsql/#changes_prometheus), [increases_over_time](https://docs.victoriametrics.com/metricsql/#increases_over_time) and [resets](https://docs.victoriametrics.com/metricsql/#resets) functions. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/767).
* BUGFIX: properly store [staleness markers](https://docs.victoriametrics.com/vmagent/#prometheus-staleness-markers) for [self-scraped metrics](https://docs.victoriametrics.com/#monitoring) on single-node VictoriaMetrics shutdown. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/943).
* BUGFIX: prevent from possible `too big indexBlockSize` panic when samples with too long label values (~64Kb) are ingested into VictoriaMetrics.

## [v1.87.14](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.87.14)
Released at 2024-02-01
**v1.87.x is a line of [LTS releases](https://docs.victoriametrics.com/lts-releases/). It contains important up-to-date bugfixes.
The v1.87.x line will be supported for at least 12 months since [v1.87.0](https://docs.victoriametrics.com/CHANGELOG.html#v1870) release**
* SECURITY: upgrade base docker image (Alpine) from 3.19.0 to 3.19.1. See [alpine 3.19.1 release notes](https://www.alpinelinux.org/posts/Alpine-3.19.1-released.html).
* BUGFIX: properly return errors from [export APIs](https://docs.victoriametrics.com/#how-to-export-time-series). Previously these errors were silently suppressed. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5649).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): respect explicitly set `series_limit: 0` in [scrape_config](https://docs.victoriametrics.com/sd_configs.html#scrape_configs). This allows removing [`series_limit` restriction](https://docs.victoriametrics.com/vmagent.html#cardinality-limiter) on a per-`scrape_config` basis when global limit is set via `-promscrape.seriesLimitPerTarget`. Previously, `0` value was ignored in favor of `-promscrape.seriesLimitPerTarget`.
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly process queries with too big lookbehind window such as `foo[100y]`. Previously, such queries could return empty responses even if `foo` is present in database. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5553).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly handle possible negative results caused by float operations precision error in rollup functions like rate() or increase(). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5571).
## [v1.87.13](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.87.13)
Released at 2024-01-17
**v1.87.x is a line of [LTS releases](https://docs.victoriametrics.com/lts-releases/). It contains important up-to-date bugfixes.
The v1.87.x line will be supported for at least 12 months since [v1.87.0](https://docs.victoriametrics.com/CHANGELOG.html#v1870) release**
* SECURITY: upgrade Go builder from Go1.21.5 to Go1.21.6. See [the list of issues addressed in Go1.21.6](https://github.com/golang/go/issues?q=milestone%3AGo1.21.6+label%3ACherryPickApproved).
* BUGFIX: `vmstorage`: added missing `-inmemoryDataFlushInterval` command-line flag, which was missing in [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html) after implementing [this feature](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3337) in [v1.85.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.85.0).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly handle queries, which wrap [rollup functions](https://docs.victoriametrics.com/MetricsQL.html#rollup-functions) with multiple arguments without explicitly specified lookbehind window in square brackets into [aggregate functions](https://docs.victoriametrics.com/MetricsQL.html#aggregate-functions). For example, `sum(quantile_over_time(0.5, process_resident_memory_bytes))` was resulting to `expecting at least 2 args to ...; got 1 args` error. Thanks to @atykhyy for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5414).
* BUGFIX: `vmstorage`: properly expire `storage/prefetchedMetricIDs` cache. Previously this cache was never expired, so it could grow big under [high churn rate](https://docs.victoriametrics.com/FAQ.html#what-is-high-churn-rate). This could result in increasing CPU load over time.
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly return results from [bottomk](https://docs.victoriametrics.com/MetricsQL.html#bottomk) and `bottomk_...` functions when some of these results contain NaN values. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5506). Thanks to @xiaozongyang for [the fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5509).
* BUGFIX: all: fix potential panic during components shutdown when [metrics push](https://docs.victoriametrics.com/#push-metrics) is configured. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5548). Thanks to @zhdd99 for the [pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5549).
