## tip
|
||||
|
||||
**Update note 1:** the `indexdb/tagFilters` cache type at [/metrics](https://docs.victoriametrics.com/#monitoring) has been renamed to `indexdb/tagFiltersToMetricIDs` in order to make its puropose more clear.
|
||||
|
||||
* FEATURE: allow limiting memory usage on a per-query basis with `-search.maxMemoryPerQuery` command-line flag. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3203).
|
||||
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): drop all the labels with `__` prefix from discovered targets in the same way as Prometheus does according to [this article](https://www.robustperception.io/life-of-a-label/). Previously the following labels were available during [metric-level relabeling](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#metric_relabel_configs): `__address__`, `__scheme__`, `__metrics_path__`, `__scrape_interval__`, `__scrape_timeout__`, `__param_*`. Now these labels are available only during [target-level relabeling](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#relabel_config). This should reduce CPU usage and memory usage for `vmagent` setups, which scrape big number of targets.
|
||||
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): improve the performance for metric-level [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling), which can be applied via `metric_relabel_configs` section at [scrape_configs](https://docs.victoriametrics.com/sd_configs.html#scrape_configs), via `-remoteWrite.relabelConfig` or via `-remoteWrite.urlRelabelConfig` command-line options.

|
||||
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): limit the number of plotted series. This should prevent from browser crashes or hangs when the query returns big number of time series. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3155).
|
||||
* FEATURE: log error if some environment variables referred at `-promscrape.config` via `%{ENV_VAR}` aren't found. This should prevent from silent using incorrect config files.
|
||||
* FEATURE: immediately shut down VictoriaMetrics apps on the second SIGINT or SIGTERM signal if they couldn't be finished gracefully for some reason after receiving the first signal.
|
||||
* FEATURE: improve the performance of [/api/v1/series](https://docs.victoriametrics.com/url-examples.html#apiv1series) endpoint by eliminating loading of unused `TSID` data during the API call.
|
||||
|
||||
* 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: [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.
