 ---
 Please find the changelog for VictoriaMetrics Anomaly Detection below.
 
+## v1.29.7
+Released: 2026-06-25
+
+- UI: updated [vmanomaly UI](https://docs.victoriametrics.com/anomaly-detection/ui/) from [v1.7.1](https://docs.victoriametrics.com/anomaly-detection/ui/#v171) to [v1.7.2](https://docs.victoriametrics.com/anomaly-detection/ui/#v172), see respective [release notes](https://docs.victoriametrics.com/anomaly-detection/ui/#v172) for details. Notable mentions include `api/v1/server/model` endpoint for accessing production models config and queries from UI, manually or through [AI assistant](https://docs.victoriametrics.com/anomaly-detection/ui/#ai-assistance).
+
+- IMPROVEMENT: Increased high-cardinality inference scaling by optionally scattering periodic infer jobs to reduce contention on shared resources (e.g. datasource, CPU, RAM) when `settings.n_workers > 1` and `scheduler.infer_every` is smaller than the total time to fetch and process all queries. This is controlled by new `scatter_infer_jobs` boolean argument of [Periodic Scheduler](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/#parameters-1) (default: `false`).
+
+- IMPROVEMENT: Optimized internal batching for reader post-fetch series processing, exposing reader processing queue depth (`vmanomaly_reader_processing_tasks_queued` [metric](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#reader-behaviour-metrics)), and clarifying inference skip logs after data fetch timeouts. See `series_processing_batch_size` argument of [VmReader](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader) and [VLogsReader](https://docs.victoriametrics.com/anomaly-detection/components/reader/#victorialogs-reader) for details.
+
+- IMPROVEMENT: Refined `VmReader` and `VLogsReader` logging after datasource request failures by suppressing the follow-up generic "No data" or "No unseen data" warning for failed fetches. Failed requests now keep the original datasource error while empty successful responses still emit the no-data warning.
+
+## v1.29.6
+Released: 2026-06-17
+
+- BUGFIX: Fixed `VLogsReader` startup and query execution when `tenant_id` is omitted or provided in short account-only form such as `"0"`. Omitted or empty tenant IDs are treated as single-node/no-tenant mode, and account-only tenant IDs are expanded to `accountID:0` before adding VictoriaLogs `AccountID`/`ProjectID` params or VM tenant labels.
+
+- BUGFIX: Hardened [`OnlineMADModel`](https://docs.victoriametrics.com/anomaly-detection/components/models/#online-mad) anomaly scoring for perfectly constant time series (all values identical). The model now keeps a small deterministic prediction interval when the learned MAD is zero, so values deviating from an unknown constant baseline can produce `anomaly_score > 1` (previously, all anomaly scores were `0`).
+
+## v1.29.5
+Released: 2026-06-11
+
+- UI: Updated [vmanomaly UI](https://docs.victoriametrics.com/anomaly-detection/ui/) from [v1.7.0](https://docs.victoriametrics.com/anomaly-detection/ui/#v170) to [v1.7.1](https://docs.victoriametrics.com/anomaly-detection/ui/#v171), see respective [release notes](https://docs.victoriametrics.com/anomaly-detection/ui/#v171) for details.
+
+- IMPROVEMENT: Redesigned [hot reload](https://docs.victoriametrics.com/anomaly-detection/components/#hot-reload) config change detection to content-based polling with configurable `-configCheckInterval`, improving reliability for Kubernetes ConfigMap symlink rotations and other filesystems where event delivery can be inconsistent.
+
+- IMPROVEMENT: Refined config validation errors for broken or invalid config sections, so startup and reload failures point to the affected section more clearly (e.g. YAML indentation typos).
+
+- IMPROVEMENT: Tightened config validation for [`PeriodicScheduler`](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/#periodic-scheduler) `infer_every` and [`IsolationForestModel`](https://docs.victoriametrics.com/anomaly-detection/components/models/#isolation-forest-multivariate) `contamination`, including clearer handling of missing scheduler intervals, numeric contamination strings, and invalid non-finite values.
+
+- BUGFIX: Fixed a multiprocessing startup issue with `settings.n_workers > 1` that could leave scheduled data fetch or successive inference jobs stuck and repeatedly skipped by internal scheduler.
+
+- BUGFIX: Bounded [`VmReader`](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader) and [`VLogsReader`](https://docs.victoriametrics.com/anomaly-detection/components/reader/#victorialogs-reader) data fetch and post-fetch processing waits so stalled datasource reads or multiprocessing dataframe creation no longer keep [`PeriodicScheduler`](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/#periodic-scheduler) `data_fetch` jobs running indefinitely. Previously, such stuck jobs could keep internal scheduler's `max_instances=1` slot per (scheduler, query) pair occupied, causing future data fetch, fit, or infer runs to be skipped until vmanomaly was restarted. The config validator now also warns when the configured reader timeout budget can exceed the connected scheduler interval.

 - Configure the **inference frequency** in the [scheduler](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/) section of the configuration file.
 - Ensure that `infer_every` aligns with your **minimum required alerting frequency**.
   - For example, if receiving **alerts every 15 minutes** is sufficient (when `anomaly_score > 1`), set `infer_every` to match `reader.sampling_period` or override it per query via `reader.queries.query_xxx.step` for an optimal setup.
+- Set `scheduler.scatter_infer_jobs` {{% available_from "v1.29.7" anomaly %}} [arg](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/#parameters-1) to `true` to allow for equal distribution of inference jobs across `infer_every` intervals, which can further enhance parallel processing efficiency and reduce resource contention when `reader.queries` contains a large number of queries.
 
 **Reader**:
 - Setup the datasource to read data from in the [reader](https://docs.victoriametrics.com/anomaly-detection/components/reader/) section. Include tenant ID if using a [cluster version of VictoriaMetrics](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/) (`multitenant` value {{% available_from "v1.16.2" anomaly %}} can be also used here).
 - Define queries for input data using [MetricsQL](https://docs.victoriametrics.com/victoriametrics/metricsql/) under `reader.queries` section. Note, it's possible to override reader-level arguments at query level for increased flexibility, e.g. specifying per-query [timezone](https://docs.victoriametrics.com/anomaly-detection/faq/#handling-timezones) or [sampling period](https://docs.victoriametrics.com/anomaly-detection/components/reader/#config-parameters).
 - For longer `fit_window` intervals in scheduler, consider splitting queries into smaller time ranges to avoid excessive memory usage, timeouts and hitting server-side constraints, so they can be queried separately and reconstructed on `vmanomaly` side. Please refer to this [example](https://docs.victoriametrics.com/anomaly-detection/faq/#handling-large-queries-in-vmanomaly) for more details.
+- Set `reader.series_processing_batch_size` {{% available_from "v1.29.7" anomaly %}} [arg](https://docs.victoriametrics.com/anomaly-detection/components/reader/#config-parameters) to a reasonable value (4-16, default is 8) to balance between memory usage and processing speed when preparing data for fit or infer stages.

This is particularly useful for scenarios where log data needs to be analyzed for unusual patterns or behaviors, such as error rates or request latencies.

 ## Changelog
 
+### v1.7.2
+Released: 2026-06-25
+
+vmanomaly version: [v1.29.7](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1297)
+
+- FEATURE: Added controls for selecting server-configured scheduled models (drop-down inside [model wizard](#model-panel)) and browsing scheduled queries from the running vmanomaly instance ("Queries" button, "scheduled queries" tab).
+
+- IMPROVEMENT: Surfaced datasource fetch failures from ad-hoc VMUI raw queries as query-level errors instead of returning a successful empty result that triggers a generic "No match" warning. Now the user can see the actual error message from the datasource (e.g. "unauthorized", "not found", etc.) and take appropriate action.
+
+- BUGFIX: Fixed [UI/query-server](#settings-panel) handling of VictoriaMetrics datasource URLs that already include `/select/multitenant/prometheus`. Such URLs are now recognized as cluster datasource URLs, preserving the multitenant path when proxying VMUI requests and allowing `server.use_reader_connection_settings` to reuse [configured reader credentials for authenticated datasources](#authentication).
+
+- BUGFIX: Fixed [settings](#settings-panel) inputs for server and datasource URLs so editing, deleting, or pasting text is no longer immediately reverted to the previous value before applying changes.
+
+- BUGFIX: Fixed [model wizard](#model-panel) settings for [`IsolationForestModel`](https://docs.victoriametrics.com/anomaly-detection/components/models/#isolation-forest-multivariate) `contamination`, allowing decimal float values such as `0.1` or `0,1` to be typed or pasted without being collapsed to `0`, while preserving the `"auto"` value.

+
+vmanomaly version: [v1.29.5](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1295)
+
+- FEATURE: Added bulk Apply/Decline actions for [Copilot](#ai-assistance) chat suggestions.
+
+- BUGFIX: Fixed modal windows closing when the mouse is released outside the window during text selection.
+
+- BUGFIX: Fixed tooltip hover behavior so tooltips do not disappear while the cursor moves into the hover content.

 ### How it works
 
-It works by watching for file system events, such as modifications, creations, or deletions of `.yml|.yaml` files in the specified directories. When a change is detected, the service will attempt to reload the configuration files, rebuild the [global config](https://docs.victoriametrics.com/anomaly-detection/scaling-vmanomaly/#global-configuration) and reinitialize the components. If the reload is successful, the `vmanomaly_config_reloads_total` metric will be incremented for `status="success"` label, otherwise it will be incremented with `status="failure"` label and a respective error message on config validation failure(s) will be logged.
+It works by checking watched `.yml|.yaml` file contents in the specified files or directories on the configured interval `-configCheckInterval` (default is `30s`) {{% available_from "v1.29.5" anomaly %}}. When a content change is detected, the service will attempt to reload the configuration files after the existing debounce window, rebuild the [global config](https://docs.victoriametrics.com/anomaly-detection/scaling-vmanomaly/#global-configuration) and reinitialize the components. If the reload is successful, the `vmanomaly_config_reloads_total` metric will be incremented for `status="success"` label, otherwise it will be incremented with `status="failure"` label and a respective error message on config validation failure(s) will be logged.
 
 > If the reload fails, the service will log an error message indicating the reason for the failure, and the **previous configuration will remain active until a successful reload occurs** to preserve the service's stability. This means that if there are errors in the new configuration, the service will continue to operate with the last valid configuration until the issues are resolved.

-**Objective**
 
-Setup Victoria Metrics Cluster with support of multiple retention periods within one installation.
+> [VictoriaMetrics Enterprise](https://docs.victoriametrics.com/victoriametrics/enterprise/) supports specifying multiple retentions for distinct sets of time series and tenants. If you are an Enterprise user, [configure multiple retentions directly through retention filters](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#retention-filters) instead of following this guide.
 
-**Enterprise Solution**
+This guide explains how to set up multiple retentions using an [open-source VictoriaMetrics Cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/).
 
-[VictoriaMetrics Enterprise](https://docs.victoriametrics.com/victoriametrics/enterprise/) supports specifying multiple retentions
-for distinct sets of time series and [tenants](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#multitenancy)
-via [retention filters](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#retention-filters).
+## Overview
 
-**Open Source Solution**
+VictoriaMetrics retains metrics by default for **1 month**. You can change data retention with the [`-retentionPeriod` command-line flag](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#retention), but this value applies to **all time series stored** on a given `vmstorage` node and cannot be customized per tenant or per metric in the open source version. 
 
-Community version of VictoriaMetrics supports only one retention period per `vmstorage` node via [-retentionPeriod](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#retention) command-line flag.
+The core idea of this guide is to run **separate logic groups of storages** (or even clusters) with individual `-retentionPeriod` settings, while still providing a single unified write and read path via vmagent and vmselect.
 
-A multi-retention setup can be implemented by dividing a [victoriametrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/) into logical groups with different retentions.
+## Multi-Retention Architecture
 
-Example:
-Setup should handle 3 different retention groups 3months, 1year and 3 years.
-Solution contains 3 groups of vmstorages + vminserts and one group of vmselects. Routing is done by [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/)
-by [splitting data streams](https://docs.victoriametrics.com/victoriametrics/vmagent/#splitting-data-streams-among-multiple-systems). 
-The [-retentionPeriod](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#retention) sets how long to keep the metrics.
+To support multiple retentions with the open source version of VictoriaMetrics cluster, you can split the cluster into several logical groups of storage nodes. Each group is configured with a different `-retentionPeriod` and receives only the data that must follow that retention. 
 
-The diagram below shows a proposed solution
+Each storage group is connected to a separate vminsert, while a shared vmselect layer queries across all storage groups so that dashboards and alerts continue to see a single unified VictoriaMetrics backend.
 
 ![Setup](setup.webp)
 
-**Implementation Details**
+In the example used throughout this guide, the cluster is divided into three groups: 
 
-1. Groups of vminserts A know about only vmstorages A and this is explicitly specified via `-storageNode` [configuration](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#cluster-setup). 
-1. Groups of vminserts B know about only vmstorages B and this is explicitly specified via `-storageNode` [configuration](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#cluster-setup). 
-1. Groups of vminserts C know about only vmstorages C and this is explicitly specified via `-storageNode` [configuration](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#cluster-setup). 
-1. vmselect reads data from all vmstorage nodes via `-storageNode` [configuration](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#cluster-setup) 
-   with [deduplication](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#deduplication) setting equal to vmagent's scrape interval or minimum interval between collected samples. 
-1. vmagent routes incoming metrics to the given set of `vminsert` nodes using relabeling rules specified at `-remoteWrite.urlRelabelConfig` [configuration](https://docs.victoriametrics.com/victoriametrics/relabeling/).
+- Group A: 3-month retention.
+- Group B: 1-year retention.
+- Group C: 3-year retention. 
 
-**Multi-Tenant Setup**
+Metrics are routed to the appropriate vminsert group by splitting data streams in vmagent, so each time series is sent to exactly one retention group instead of being replicated to all groups. See [Deploying vmagent](https://docs.victoriametrics.com/guides/guide-vmcluster-multiple-retention-setup/#step3) for an example of label‑based routing that implements this split. An optional [vmauth](https://docs.victoriametrics.com/guides/guide-vmcluster-multiple-retention-setup/#additional-enhancements) layer can be added on top to restrict access to specific sub‑clusters or tenants while still keeping a unified write and read path.
 
-Every group of vmstorages can handle one tenant or multiple one. Different groups can have overlapping tenants. As vmselect reads from all vmstorage nodes, the data is aggregated on its level.
+## Implementing Multi-Retention on Kubernetes
 
-**Additional Enhancements**
+In this section, we'll install and configure the components for a multi-retention deployment of the VictoriaMetrics cluster. See [Kubernetes monitoring with VictoriaMetrics Cluster](https://docs.victoriametrics.com/guides/k8s-monitoring-via-vm-cluster/) for details on running VictoriaMetrics in Kubernetes.
 
-You can set up [vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/) for routing data to the given vminsert group depending on the needed retention.
+Run the following command to add the VictoriaMetrics Helm repository:
+
+```shell
+helm repo add vm https://victoriametrics.github.io/helm-charts/
+helm repo update
+```
+
+### Step 1: Deploying storage groups {#step1}
+
+We'll create three storage groups. Each has a different retention period and disk size. Read [Understand Your Setup Size](https://docs.victoriametrics.com/guides/understand-your-setup-size/) to estimate how much space you will need for each group. The following table is shown as an example:
+
+
+| Group        | Retention Period | Total disk size       |
+|--------------|------------------|-----------------------|
+| `vmcluster-a`  | 3 months (`3M`)    | 80 Gi                 |
+| `vmcluster-b`  | 1 year (`1Y`)      | 300 Gi                |
+| `vmcluster-c`  | 3 years (`3Y`)     | 900 Gi                |
+
+Create a Helm values file for Group A.
+
+```shell
+cat <<EOF > vmcluster-a.yaml
+vmstorage:
+  enabled: true
+  replicaCount: 1
+  persistence:
+    size: 80Gi
+  extraArgs:
+    retentionPeriod: 3M
+  podLabels:
+    retention-group: a
+
+vminsert:
+  enabled: true
+  podLabels:
+    retention-group: a
+
+vmselect:
+  enabled: false
+EOF
+```
+
+The values file above creates vminsert and vmstorage services while turning off vmselect, which we'll deploy separately. The `retentionPeriod` flag configures how long data is kept in this group.
+
+Create the values files for Group B and Group C:
+
+```shell
+cat <<EOF > vmcluster-b.yaml
+vmstorage:
+  enabled: true
+  replicaCount: 1
+  persistence:
+    size: 300Gi
+  extraArgs:
+    retentionPeriod: 1y
+  podLabels:
+    retention-group: b
+
+vminsert:
+  enabled: true
+  podLabels:
+    retention-group: b
+
+vmselect:
+  enabled: false
+EOF
+
+
+cat <<EOF > vmcluster-c.yaml
+vmstorage:
+  enabled: true
+  replicaCount: 1
+  persistence:
+    size: 900Gi
+  extraArgs:
+    retentionPeriod: 3y
+  podLabels:
+    retention-group: c
+
+vminsert:
+  enabled: true
+  podLabels:
+    retention-group: c
+
+vmselect:
+  enabled: false
+EOF
+```
+
+Deploy the three storage groups with:
+
+```shell
+helm upgrade --install vmcluster-a vm/victoria-metrics-cluster -f vmcluster-a.yaml
+helm upgrade --install vmcluster-b vm/victoria-metrics-cluster -f vmcluster-b.yaml
+helm upgrade --install vmcluster-c vm/victoria-metrics-cluster -f vmcluster-c.yaml
+
+# Wait for all storage pods to be ready
+kubectl rollout status statefulset -l app.kubernetes.io/instance=vmcluster-a
+kubectl rollout status statefulset -l app.kubernetes.io/instance=vmcluster-b
+kubectl rollout status statefulset -l app.kubernetes.io/instance=vmcluster-c
+```
+
+### Step 2: Deploying vmselect {#step2}
+
+Next, we'll deploy a vmselect service to route queries to the storage groups.
+
+Create a Helm values file with:
+
+```shell
+cat <<EOF >vmselect.yaml
+vmstorage:
+  enabled: false
+
+vminsert:
+  enabled: false
+
+vmselect:
+  enabled: true
+  replicaCount: 1
+  suppressStorageFQDNsRender: true
+  extraArgs:
+    # Each list item is a single -storageNode flag. In this example, there is
+    # one vmstorage pod per retention group, so each entry contains a single host.
+    # If you run multiple pods per group, list them as comma-separated hosts
+    # in the same -storageNode value.
+    #
+    # The FQDN format is:
+    #   <pod>.<svc>.default.svc
+    # where pod = <release>-victoria-metrics-cluster-vmstorage-<N>
+    # and   svc = <release>-victoria-metrics-cluster-vmstorage
+    storageNode:
+      - "vmcluster-a-victoria-metrics-cluster-vmstorage-0.vmcluster-a-victoria-metrics-cluster-vmstorage.default.svc:8401"
+      - "vmcluster-b-victoria-metrics-cluster-vmstorage-0.vmcluster-b-victoria-metrics-cluster-vmstorage.default.svc:8401"
+      - "vmcluster-c-victoria-metrics-cluster-vmstorage-0.vmcluster-c-victoria-metrics-cluster-vmstorage.default.svc:8401"
+EOF
+```
+
+Let's break down the file above:
+
+- Deploys vmselect as a separate Helm release. 
+- Disables vminsert and vmstorage as these services were already deployed in Step 1.
+- `suppressStorageFQDNsRender: true` turns off automatic FQDN generation for storage nodes. By default, the Helm chart auto-generates `-storageNodes` flags, but since `vmstorage` has been disabled, we need to supply them manually in `extraArgs`.
+- In `extraArgs.storageNode:` we define the vmstorage endpoints for queries. On querying, vmselect merges results across all the specified vmstorages to provide a unified view of the data.
+
+Deploy the `vmselect` release with:
+
+```shell
+helm upgrade --install vmselect vm/victoria-metrics-cluster -f vmselect.yaml
+```
+
+### Step 3: Deploying vmagent {#step3}
+
+We'll use `vmagent` to route incoming metrics to the correct retention group. For example, we can use a `retention` label for mapping metrics to storage groups in the following way:
+
+| `retention` label | Storage Group |
+|-------------------|--------------|
+| `"3mo"`           | `vmcluster-a` |
+| `"1yr"`           | `vmcluster-b` |
+| `"3yr"`           | `vmcluster-c` |
+
+
+Create the values file for vmagent:
+
+```shell
+cat <<EOF >vmagent.yaml
+service:
+  enabled: true
+remoteWrite:
+  # Group A: receives metrics with retention="3mo"
+  - url: http://vmcluster-a-victoria-metrics-cluster-vminsert:8480/insert/0/prometheus/api/v1/write
+    urlRelabelConfig:
+      - if: '{retention="3mo"}'
+        action: keep
+  # Group B: receives metrics with retention="1yr"
+  - url: http://vmcluster-b-victoria-metrics-cluster-vminsert:8480/insert/0/prometheus/api/v1/write
+    urlRelabelConfig:
+      - if: '{retention="1yr"}'
+        action: keep
+  # Group C: receives metrics with retention="3yr"
+  - url: http://vmcluster-c-victoria-metrics-cluster-vminsert:8480/insert/0/prometheus/api/v1/write
+    urlRelabelConfig:
+      - if: '{retention="3yr"}'
+        action: keep
+EOF
+```
+
+> Metrics without a matching `retention` label are silently dropped by the `keep` rules. You must ensure that every metric is labeled, or use a different routing configuration.
+
+Now deploy the vmagent release:
+
+```shell
+helm upgrade --install vmagent vm/victoria-metrics-agent -f vmagent.yaml
+```
+
+Wait for vmagent to become ready:
+
+```shell
+kubectl rollout status deploy/vmagent-victoria-metrics-agent
+```
+
+### Step 4: Verification
+
+We can send test data to verify that the data is flowing to the correct storage group.
+
+First, port-forward vmagent and vmselect:
+
+```shell
+VMAGENT_SVC=$(kubectl get svc -l app.kubernetes.io/instance=vmagent -o jsonpath='{.items[0].metadata.name}')
+kubectl port-forward "svc/$VMAGENT_SVC" 8429 &
+
+VMSELECT_SVC=$(kubectl get svc -l app.kubernetes.io/instance=vmselect -o jsonpath='{.items[0].metadata.name}')
+kubectl port-forward "svc/$VMSELECT_SVC" 8481 &
+```
+
+Send test metrics directly to vmagent's HTTP endpoint to exercise all three retention labels:
+
+```shell
+POD=$(kubectl get pod -l app.kubernetes.io/instance=vmagent -o jsonpath='{.items[0].metadata.name}')
+
+for retention in 3mo 1yr 3yr; do
+  kubectl exec "$POD" -- wget -qO- --post-data="test_routing{retention=\"${retention}\"} 1.0" \
+    "http://127.0.0.1:8429/api/v1/import/prometheus"
+done
+```
+
+Query the data back from vmselect (it may take around 30-60 seconds for new data to be available for queries):
+
+```shell
+for retention in 3mo 1yr 3yr; do
+  echo "-> retention=${retention}"
+  curl -s "http://localhost:8481/select/0/prometheus/api/v1/query" \
+    --data-urlencode "query=test_routing{retention=\"${retention}\"}"
+  echo
+done
+```
+
+You can also check that vmagent is forwarding data to all three groups:
+
+```shell
+curl -s http://localhost:8429/metrics | grep vmagent_remotewrite_blocks_sent_total
+```
+
+Each `url="N:secret-url"` corresponds to one `remoteWrite` entry (N=1 for Group A, N=2 for Group B, N=3 for Group C). Non-zero values confirm data is flowing.
+
+## Alternative Routing by Existing Labels
+
+The example setup above relies on a synthetic `retention` label to exist in every incoming metric.
+
+If having a `retention` label in every metric isn't practical, you can, as an alternative, rely on existing labels to map data to the correct storage group.
+
+The following example configures vmagent to route metrics based on the `environment` and `team` labels:
+
+```yaml
+# vmagent.yaml
+remoteWrite:
+  # send dev and staging data to Group A
+  - url: "http://vmcluster-a-victoria-metrics-cluster-vminsert:8480/insert/0/prometheus/api/v1/write"
+    urlRelabelConfig:
+      - if: {environment=~"dev|staging"}
+        action: keep
+  # send prod data to Group B
+  - url: "http://vmcluster-b-victoria-metrics-cluster-vminsert:8480/insert/0/prometheus/api/v1/write"
+    urlRelabelConfig:
+      - if: {environment=~"prod|production"}
+        action: keep
+  # send data from Infra and SRE teams to Group C
+  - url: "http://vmcluster-c-victoria-metrics-cluster-vminsert:8480/insert/0/prometheus/api/v1/write"
+    urlRelabelConfig:
+      - if: {team=~"infra|sre"}
+        action: keep

+
+## Additional Enhancements
+
+You can set up [vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/) to route data to the specified vminsert group based on the required retention or to restrict which data different users can query.
+
+The following [`-auth.config`](https://docs.victoriametrics.com/victoriametrics/vmauth/#quick-start) example exposes the same vmselect backend via vmauth with two users using basic auth:
+
+- `admin`: can query **all** data across all retention groups.
+- `dev`: can query **only** time series that have `team="dev"` label, enforced via the `extra_label` query argument.
+
+```yaml
+users:
+  # User with access to all data across all retention groups
+  - username: "admin"
+    password: "foo"
+    url_map:
+      - src_paths:
+          - "/api/v1/query"
+          - "/api/v1/query_range"
+          - "/api/v1/series"
+          - "/api/v1/labels"
+          - "/api/v1/label/.+/values"
+        # vmselect service that aggregates all vmstorage groups
+        url_prefix: "http://vmselect-victoria-metrics-cluster-vmselect:8481/select/0/prometheus"
+
+  # User restricted to Dev team data only
+  - username: "dev"
+    password: "bar"
+    url_map:
+      - src_paths:
+          - "/api/v1/query"
+          - "/api/v1/query_range"
+          - "/api/v1/series"
+          - "/api/v1/labels"
+          - "/api/v1/label/.+/values"
+        # Same vmselect backend, but enforce label filter at query time
+        # by adding extra_label=team=dev to every proxied request
+        url_prefix: "http://vmselect-victoria-metrics-cluster-vmselect:8481/select/0/prometheus/?extra_label=team=dev"
+```
+
+This is useful for restricting access by team, environment, or tenant without changing the underlying storage topology.

 ### Reporting a Vulnerability
 
 Please report any security issues to <security@victoriametrics.com>
 
+### CVE handling policy
+
+**Source code:** Go dependencies are scanned by [govulncheck](https://pkg.go.dev/golang.org/x/vuln/cmd/govulncheck) in CI.
+All vulnerabilities must be fixed before the next scheduled release and backported to [LTS releases](https://docs.victoriametrics.com/victoriametrics/lts-releases/).
+
+**Docker images:** CVE findings in the [Alpine](https://security.alpinelinux.org/) base image pose minimal risk since VictoriaMetrics binaries are statically compiled with no OS dependencies.
+When detected, only the Alpine base tag is updated.
+Releases proceed as planned even if upstream fixes are not yet available.
+For maximum security, hardened [scratch](https://hub.docker.com/_/scratch)-based images are also provided.
+All images are continuously scanned by Docker Hub and verified before release using [grype](https://github.com/anchore/grype).
+

   which are intended for serving public requests and performing authorization with [TLS termination](https://en.wikipedia.org/wiki/TLS_termination_proxy).
-* All the requests from untrusted networks to VictoriaMetrics components must go through auth proxy such as [vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/)
+* All the requests from untrusted networks to VictoriaMetrics components must go through an auth proxy, such as [vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/)
   or [vmgateway](https://docs.victoriametrics.com/victoriametrics/vmgateway/). The proxy must be set up with proper authentication and authorization.
 * Prefer using lists of allowed API endpoints, while disallowing access to other endpoints when configuring [vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/)

-### CVE handling policy
-
-**Source code:** Go dependencies are scanned by [govulncheck](https://pkg.go.dev/golang.org/x/vuln/cmd/govulncheck) in CI. 
-All vulnerabilities must be fixed before next scheduled release and backported to [LTS releases](https://docs.victoriametrics.com/victoriametrics/lts-releases/).
-
-**Docker images:** CVE findings in [Alpine](https://security.alpinelinux.org/) base image pose minimal risk since VictoriaMetrics binaries are statically compiled with no OS dependencies.
-When detected, only the Alpine base tag is updated.
-Releases proceed as planned even if upstream fixes are not yet available.
-For maximum security, hardened [scratch](https://hub.docker.com/_/scratch)-based images are also provided.
-All images are continuously scanned by Docker Hub and verified before release using [grype](https://github.com/anchore/grype).

-* BUGFIX: [stream aggregation](https://docs.victoriametrics.com/victoriametrics/stream-aggregation/): fix issue with producing aggregated samples with identical timestamps between flushes. See PR [#10808](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/10808) for details.
+* SECURITY: upgrade base docker image (Alpine) from 3.23.4 to 3.24.1. See [Alpine 3.24.1 release notes](https://www.alpinelinux.org/posts/Alpine-3.24.1-released.html).
+
+* FEATURE: `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): expose `vm_max_memory_per_query` metric reflecting the `-search.maxMemoryPerQuery` limit. Create `VMSelectConcurrentQueriesExceedMemoryLimit` alert to warn when OOMs are possible due to misconfiguration of `-search.maxMemoryPerQuery` and max concurrent queries.
+
+* FEATURE: [vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/): add `default_vm_access_claim` field into `jwt` section of auth config. It could be used at [JWT claim placeholders](https://docs.victoriametrics.com/victoriametrics/vmauth/#jwt-claim-based-request-templating), if `JWT` token doesn't have `vm_access` claim. See [#11054](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11054).

See [#11113](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/11113). Thanks to @bennf for contribution.
+* FEATURE: [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/) and `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): add `optimize_repeated_binary_op_subexprs=1` query arg to [/api/v1/query_range](https://docs.victoriametrics.com/victoriametrics/keyconcepts/#range-query) for executing binary operator sides sequentially when they share the same optimized aggregate rollup result expression. This allows the second side to reuse rollup result cache populated by the first side. See [#10575](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10575).

See [#11180](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11180).
+
+* BUGFIX: all VictoriaMetrics components: cancel in-flight HTTP requests shortly before `-http.maxGracefulShutdownDuration` elapses during graceful shutdown, so they can drain and the shutdown completes cleanly within that window instead of timing out and exiting via `logger.Fatalf` -> `os.Exit`. This prevents skipping the storage flush and losing in-memory data when long-lived requests are in flight (such as VictoriaLogs live tailing).
