 * 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).
 
+* 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): 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)
