* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add `-remoteWrite.disableOnDiskQueue` command-line flag, which can be used for disabling data queueing to disk when the remote storage cannot keep up with the data ingestion rate. See [these docs](https://docs.victoriametrics.com/vmagent.html#disabling-on-disk-persistence) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2110).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add support for reading and writing samples via [Google PubSub](https://cloud.google.com/pubsub). See [these docs](https://docs.victoriametrics.com/vmagent.html#google-pubsub-integration).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add support for Datadog `/api/v2/series` and `/api/beta/sketches` ingestion protocols to vmagent/vminsert components. See this [doc](https://docs.victoriametrics.com/#how-to-send-data-from-datadog-agent) for examples. Thanks to @AndrewChubatiuk for the [pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5094).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): show all the dropped targets together with the reason why they are dropped at `http://vmagent:8429/service-discovery` page. Previously targets, which were dropped because of [target sharding](https://docs.victoriametrics.com/vmagent.html#scraping-big-number-of-targets) weren't displayed on this page. This could complicate service discovery debugging. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5389).
* FEATURE: reduce the default value for `-import.maxLineLen` command-line flag from 100MB to 10MB in order to prevent excessive memory usage during data import via [/api/v1/import](https://docs.victoriametrics.com/#how-to-import-data-in-json-line-format).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add `keep_if_contains` and `drop_if_contains` relabeling actions. See [these docs](https://docs.victoriametrics.com/vmagent.html#relabeling-enhancements) for details.
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): add [day_of_year()](https://docs.victoriametrics.com/MetricsQL.html#day_of_year) function, which returns the day of the year for each of the given unix timestamps. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5345) for details. Thanks to @luckyxiaoqiang for the [pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5368/).
