 * FEATURE: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/) and [vmalert](https://docs.victoriametrics.com/victoriametrics/vmalert/): add `basicAuth.usernameFile` command-line flags for reading basic auth username from a file, similar to the existing `basicAuth.passwordFile`. The file is re-read every second. See [#9436](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9436). Thanks to @kimjune01 for the contribution.
-* FEATURE: `vminsert` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): add `clusternative.tls` `vminsert` configuration flags for [multi-level cluster setups](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#multi-level-cluster-setup). See [#10958](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10958).
 * FEATURE: [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/), `vminsert` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/) and [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/): add `-opentelemetry.labelNameUnderscoreSanitization` command-line flag to control whether to enable prepending of `key` to labels starting with `_` when `-opentelemetry.usePrometheusNaming` is enabled. See [OpenTelemetry](https://docs.victoriametrics.com/victoriametrics/integrations/opentelemetry/) docs and [#9663](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9663). Thanks to @andriibeee for the contribution.
 * FEATURE: [vmui](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#vmui): improve the [Top Queries](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#top-queries) table UI. Duration columns now display human-readable values (e.g. `1.23s`) instead of raw seconds, memory column shows human-readable sizes (e.g. `1.23 MB`), instant queries are labeled as `instant` instead of empty string, and column headers now show tooltips with descriptions. See [#10790](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/10790).
-* FEATURE: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/): drain in-memory remote write queue on shutdown within the 5-second grace period before falling back to persisting blocks to disk. See [#9996](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9996)
-* FEATURE: `vminsert` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): Improve [slowness-based rerouting](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#slowness-based-re-routing) to prevent rerouting storms under high cluster load. Previously, rerouting could cascade across storage nodes when the whole cluster was saturated, making the situation worse. Now rerouting only activates when the cluster p90 saturation is below 60%, and the slowest node is more than 20% slower than p90. See [#10876](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10876).
-* FEATURE: [vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/): add `{{.MetricsAccountID}}` and `{{.MetricsProjectID}}` [JWT claim placeholders](https://docs.victoriametrics.com/victoriametrics/vmauth/#jwt-claim-based-request-templating) for use in `headers` and `url_prefix` config fields. Previously, only the combined `{{.MetricsTenant}}` (`accountID:projectID`) JWT placeholder was supported, making it impossible to configure [multitenancy via headers](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#multitenancy-via-headers). See [#10927](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10927). Thanks to @Vinayak9769 for the contribution.
-* FEATURE: [vmui](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#vmui): display `null` values on `Raw Query` chart. `null` values can be actual `NaN` or `null` values exposed by the exporter, or [stale markers](https://docs.victoriametrics.com/victoriametrics/vmagent/#prometheus-staleness-markers). Before, vmui Raw Query was silently dropping non-numeric values. Displaying such values on the chart could improve the debugging experience. See [#10986](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/10986).
 
-* BUGFIX: [stream aggregation](https://docs.victoriametrics.com/victoriametrics/stream-aggregation/): stop emitting stale values for `quantiles(...)` outputs when a time series has no samples during the current aggregation interval. See [#10918](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/10918). Thanks to @alexei38 for the contribution.

-## What Happens to Licensed Components When a License Expires
-
-When a license expires, all licensed components continue to function normally until a restart occurs.
-
-License checks happen only at startup. If a license expires while the component is running, nothing changes; the component continues to run until the next restart. 
-
-This means you don't need to restart components to install a new license. The component automatically picks up the new license the next time it restarts. The exception is when the `-license` flag is used, because the license is supplied at startup and changing it requires restarting VictoriaMetrics with the updated flag value.
-
-If your license has expired and you decide to not renew it, you can switch to the VictoriaMetrics Open Source version without data loss, as both versions share the same data model. In doing so, however, you will lose access to the [VictoriaMetrics Enterprise features](https://docs.victoriametrics.com/victoriametrics/enterprise/#victoriametrics-enterprise-features).

-See [updating the license key](https://docs.victoriametrics.com/victoriametrics/enterprise/#updating-the-license-key) for more details.

-
-To scale the aggregation horizontally, always shard the input samples in a deterministic way. This can be achieved by

-- The sharding configuration must align with the `by` and `without` lists:
-  - Labels listed in `by` setting should be a subset of shard's routing key `-remoteWrite.shardByURL.labels`. 
-    With `-remoteWrite.shardByURL.labels=env,job` aggregator's `by` should include `by: env`, `by: job` or both: `by: [env, job]`.
-    This makes sure that all the samples for the same `env` and `job` are aggregated together and produce the complete output.
-  - Labels listed in `without` setting should be a superset of shard's routing key `--remoteWrite.shardByURL.ignoreLabels`.
-    With `-remoteWrite.shardByURL.ignoreLabels=env,job` aggegator's `without` should include at least both labels `without: [env,job]`.
-    This makes sure that `requests_total{env=test, job=foo}` and `requests_total{env=prod, job=foo}` are routed to the same aggregator
-    and are aggregated together. See also [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5938#issuecomment-2018470324).
-- Aggregating vmagents should not produce collisions: the aggregation output should be unique across all the sharded agents.
-  For example, `requests_total:5m_without_env_pod_total` produced by both `vmagent-aggr-1` and `vmagent-aggr-2` will collide
-  unless they have labels uniquely identifying them. These labels should be either preserved during sharding and aggregation config,
-  or enforced on the output via `-remoteWrite.label` - see [these docs](https://docs.victoriametrics.com/victoriametrics/stream-aggregation/#cluster-mode) for more details.

-> Never shard histograms by `le` (or `vmrange` in case of VM histograms) label. A histogram is a logical group of series differing
-only in the bucket label. All of those buckets must land on the same aggregator at the same time so it can produce a
-coherent bucket set. See more about [aggregating histograms](https://docs.victoriametrics.com/stream-aggregation/#aggregating-histograms).
