- **security** — Upgrade Go builder from Go1.26.5 to Go1.26.6
- **fixed** — Properly parse small fractional Unix timestamps in timestamp args such as start and end in /api/v1/query_range and --vm-native-filter-time-start and --vm-native-filter-time-end in vmctl
- **fixed** — Persist the previous working set cache during graceful shutdown when it is likely to contain the active working set
- **fixed** — Properly assign scrape target IP address at IPv6-only networks for docker_sd_configs
- **fixed** — Avoid suggesting the unrelated -enableTCP6 command-line flag when scraping a target over a Unix domain socket fails
- **fixed** — Respect the custom query step specified via g0.step_input when opening a URL in vmui
- **fixed** — Change the HTTP response code for Prometheus querying API requests from 422 Unprocessable Entity to 400 Bad Request when request parameters are missing or incorrect
- **fixed** — Skip labels with empty name at /api/v1/import
- **fixed** — Rename vmalert_rule_group_results_limit back to vmalert_group_rule_results_limit
- **fixed** — Properly update group-level eval_delay and eval_alignment for existing groups during runtime when config reload is triggered
- **fixed** — Scale the default -search.maxConcurrentRequests with the number of available CPU cores instead of capping it at 16

##### [v1.148.2](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.148.2)

Released at 2026-08-14

**v1.148.x is a line of [LTS releases](https://docs.victoriametrics.com/victoriametrics/lts-releases/). It contains important up-to-date bugfixes for [VictoriaMetrics enterprise](https://docs.victoriametrics.com/victoriametrics/enterprise/).
All these fixes are also included in [the latest community release](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest).
The v1.148.x line will be supported for at least 12 months since [v1.148.0](https://docs.victoriametrics.com/victoriametrics/changelog/#v11480) release**

* 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).

* BUGFIX: [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/), `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/) and [vmctl](https://docs.victoriametrics.com/victoriametrics/vmctl/): properly parse small fractional Unix timestamps in timestamp args such as `start` and `end` in `/api/v1/query_range` and `--vm-native-filter-time-start` and `--vm-native-filter-time-end` in `vmctl`. Previously, fractional Unix timestamps with the integer part below `9223372` were interpreted with the wrong unit, for example `12.0` was parsed as `12000` seconds instead of `12` seconds. See [#11324](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11324).
* BUGFIX: [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/), `vmstorage` and `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): persist the previous working set cache during graceful shutdown when it is likely to contain the active working set. This prevents saving an empty or cold current cache right after split-mode cache rotation, which could otherwise slow down ingestion or queries after restart until the cache warms up again. See [#11299](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11299).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/) and [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/): properly assign scrape target IP address at IPv6-only networks for [docker_sd_configs](https://docs.victoriametrics.com/victoriametrics/sd_configs/#docker_sd_configs). See [#10965](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10965).
* 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.
* BUGFIX: [vmui](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#vmui): respect the custom query step specified via `g0.step_input` when opening a URL. Previously, it could be reset to the automatically calculated step and potentially cause dashboards to freeze. See [#11137](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11137).
* BUGFIX: [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/) and `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): change the HTTP response code for [Prometheus querying API](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#prometheus-querying-api-usage) requests from `422 Unprocessable Entity` to `400 Bad Request` when request parameters are missing or incorrect. See [#11330](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11330).
* BUGFIX: [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/)
