 * FEATURE: all VictoriaMetrics components: improve logging for the `-memory.allowedBytes` flag to warn about excessively low value (less than 1MB). See issue [#10935](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10935).
 * 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: [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.
 * BUGFIX: [stream aggregation](https://docs.victoriametrics.com/victoriametrics/stream-aggregation/): extend delay on aggregation windows flush by the biggest lag among pushed samples. Before, the delay was calculated as 95th percentile across samples, which could underrepresent outliers and reject them from aggregation as "too old".

+Released at 2026-05-22
+
+**v1.136.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 v1.136.x line will be supported for at least 12 months since [v1.136.0](https://docs.victoriametrics.com/victoriametrics/changelog/#v11360) release**
+
+* 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.
+* BUGFIX: [stream aggregation](https://docs.victoriametrics.com/victoriametrics/stream-aggregation/): extend delay on aggregation windows flush by the biggest lag among pushed samples. Before, the delay was calculated as 95th percentile across samples, which could underrepresent outliers and reject them from aggregation as "too old". See [#10402](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10402).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/): fix a bug in [cardinality limiters](https://docs.victoriametrics.com/victoriametrics/vmagent/#cardinality-limiter) where series with different labels, like `{a="bc"}` and `{ab="c"}`, could be incorrectly treated as identical and dropped. See [#10937](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/10937).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/): hide values passed to `-remoteWrite.headers` in startup logs, `/metrics`, and `/flags`, since they can contain sensitive HTTP headers such as `Authorization` and API keys.
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/): hide values passed to `-remoteWrite.proxyURL` in startup logs, `/metrics`, and `/flags`, since they can contain sensitive credentials.
+* BUGFIX: [vmalert](https://docs.victoriametrics.com/victoriametrics/vmalert/): hide values passed to `-remoteWrite.headers`,`remoteRead.headers`, `datasource.headers` and `notifier.headers` in startup logs, `/metrics`, and `/flags`, since they can contain sensitive HTTP headers such as `Authorization` and API keys.
+* BUGFIX: `vminsert` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): properly establish [mtls](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#mtls-protection) connection between vmstorage and vminsert. Regression was introduced in v1.130.0 release for the enterprise version of vmstorage. See [#10972](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10972).
+* BUGFIX: [vmrestore](https://docs.victoriametrics.com/victoriametrics/vmrestore/): fix a bug where specifying `-storageDataPath` with a trailing slash could cause `vmrestore` to panic. See [#10823](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10823). Thanks to @utafrali for the contribution.
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/): prevent unintentional rerouting of samples to other sharding targets when one of the `-remoteWrite.url` targets with `-remoteWrite.disableOnDiskQueue` becomes blocked. Previously this could break the sharding guarantee by sending samples to wrong targets instead of dropping or retrying them. See [#10507](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10507).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/): return error on startup if `-remoteWrite.disableOnDiskQueue` is not configured uniformly across all `-remoteWrite.url` targets when `-remoteWrite.shardByURL` is enabled. Either all targets must have it enabled or all must have it disabled. See [#10507](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10507).
+* BUGFIX: [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/) and `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): hide values passed to `vmalert.proxyURL` in startup logs, `/metrics`, and `/flags`, since they can contain sensitive HTTP headers such as `Authorization` and API keys.
+* BUGFIX: [vmui](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#vmui): preserve exact series values in graph tooltips instead of rounding them by significant digits. See [#10952](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10952).
+* BUGFIX: [vmui](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#vmui): add missing `__timestamp__` and `__value__` columns to CSV exported from the table view on the Query tab. See [#10975](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10975).
