---

- **security** — Upgrade Go builder from Go1.26.5 to Go1.26.6
- **changed** — Reduce CPU usage up to 30% when matching relabeling rules with multiple if expressions containing exact metric names by skipping expressions for other metric names before evaluating their remaining label filters
- **added** — Add support for linode_sd_configs in vmagent and vmsingle for discovering scrape targets from Linode instances
- **changed** — Extend vmalert -replay.continueWithExecutionErr to also handle the 400 Bad Request response code
- **changed** — Set default value of -enableMultitenancyViaHeaders to true in vmselect and vminsert in VictoriaMetrics cluster and vmagent to enable multitenancy via headers support by default
- **added** — Add an option in vmui to customize the favicon color to distinguish between different installations opened in multiple browser tabs
- **fixed** — Avoid suggesting the unrelated -enableTCP6 command-line flag when scraping a target over a Unix domain socket fails in vmagent and vmsingle
- **fixed** — Skip labels with empty name at /api/v1/import in vmsingle and vminsert to prevent empty name labels from replacing the metric name
- **fixed** — Properly parse small fractional Unix timestamps in timestamp args such as start and end in /api/v1/query_range and vmctl filter time arguments
- **fixed** — Persist the previous working set cache during graceful shutdown in vmsingle, vmstorage and vmselect to prevent saving an empty or cold cache after split-mode cache rotation

##### [v1.150.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.150.0)

Released at 2026-08-14

**Update Note 1:** `vmselect` and `vminsert` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/), and `vmagent`: default value of `-enableMultitenancyViaHeaders` command-line flag has changed from `false` to `true`. This change enables support of [multitenancy via headers for cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#multitenancy-via-headers) and [for vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/#multitenancy-via-headers) by default. With this change, mentioned components will start supporting URLs with omitted tenant ID in the path: `https://<vmselect>:8481/select/prometheus/api/v1/query` will become a valid URL. To disable multitenancy via headers and simplified URLs set `--enableMultitenancyViaHeaders=false` on vmagent, vminsert and vmselect. 

* SECURITY: upgrade Go builder from Go1.26.5 to Go1.26.6. See [the list of issues addressed in Go1.26.6](https://github.com/golang/go/issues?q=milestone%3AGo1.26.6%20label%3ACherryPickApproved).

* FEATURE: [relabeling](https://docs.victoriametrics.com/victoriametrics/relabeling/): reduce CPU usage up to 30% when matching relabeling rules with multiple `if` expressions containing exact metric names. Expressions for other metric names are now skipped before evaluating their remaining label filters. See [#11341](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/11341). Thanks to @nevgeny for contribution.
* FEATURE: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/) and [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/): add support for [linode_sd_configs](https://docs.victoriametrics.com/victoriametrics/sd_configs/#linode_sd_configs) for discovering scrape targets from Linode instances. See [#9118](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9118). Thanks to @cxdy for contribution.
* FEATURE: [vmalert](https://docs.victoriametrics.com/victoriametrics/vmalert/): extend `-replay.continueWithExecutionErr` to also handle the `400 Bad Request` response code, since it is used for Prometheus querying API requests when request parameters are missing or incorrect. See [#11352](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/11352).
* FEATURE: `vmselect` and `vminsert` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/), and `vmagent`: set default value of `-enableMultitenancyViaHeaders` to `true`. This change enables support of [multitenancy via headers for cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#multitenancy-via-headers) and [for vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/#multitenancy-via-headers) by default, aligning VictoriaMetrics multitenancy behavior with [multitenancy in VictoriaLogs](https://docs.victoriametrics.com/victorialogs/#multitenancy). See related ticket [#11365](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11365).
* FEATURE: [vmui](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#vmui): add an option to customize the favicon color. This makes it easier to distinguish between different installations opened in multiple browser tabs. See [#11329](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11329).

* BUGFIX: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/) and [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/): avoid suggesting the unrelated `-enableTCP6` command-line flag when scraping a target over a Unix domain socket fails. See [#11320](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/11320). Thanks to @lwmacct for contribution.
