 * FEATURE: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): rename field `Query time` to `Hits query` on the Hits chart panel. The change makes it clear duration of which query is displayed.
 * FEATURE: [dashboards/kubernetes-explorer](https://github.com/VictoriaMetrics/VictoriaLogs/blob/master/dashboards/victorialogs-kubernetes-explorer.json): add new dashboard for exploring Kubernetes logs via [VictoriaLogs datasource](https://docs.victoriametrics.com/victorialogs/integrations/grafana/) in Grafana. Thanks to @sias32 for [the contribution](https://github.com/VictoriaMetrics/VictoriaLogs/pull/1254)!
 
+* BUGFIX: [OpenTelemetry data ingestion](https://docs.victoriametrics.com/victorialogs/data-ingestion/opentelemetry/): reject fields with names exceeding [128 bytes](https://docs.victoriametrics.com/victorialogs/faq/#what-is-the-maximum-supported-field-name-length) to prevent high memory consumption when processing deeply nested structures. See [#1321](https://github.com/VictoriaMetrics/VictoriaLogs/issues/1321).
 * BUGFIX: [vlagent](https://docs.victoriametrics.com/victorialogs/vlagent/): hide sensitive values passed via `-remoteWrite.proxyURL` in `/metrics`, `/flags`, and startup logs. Previously these values could be exposed in plain text. See [#1320](https://github.com/VictoriaMetrics/VictoriaLogs/pull/1320).
 * BUGFIX: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): sanitize markdown URLs in logs rendered with `markdown parsing` enabled, allowing only `http`, `https`, `mailto`, and `tel` schemes for active links and images. See [#1313](https://github.com/VictoriaMetrics/VictoriaLogs/pull/1313).
 * BUGFIX: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): improve context view highlight visibility in dark theme. The selected log entry is now highlighted with a more visible blue tint instead of barely visible gray background. See [#1196](https://github.com/VictoriaMetrics/VictoriaLogs/issues/1196).
 * BUGFIX: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): fix live tab ignoring selected stream filters. See [#1342](https://github.com/VictoriaMetrics/VictoriaLogs/issues/1342).
 * BUGFIX: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): fix stream context view where the selected log overlapped transparently with content below when scrolling. See [#1185](https://github.com/VictoriaMetrics/VictoriaLogs/issues/1185).
 * BUGFIX: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): fix browser navigation issues where the UI state didn't update on URL changes. See [#1056](https://github.com/VictoriaMetrics/VictoriaLogs/issues/1056).
+* BUGFIX: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): fix incorrect stream_context selection for logs with identical timestamps. See [#1199](https://github.com/VictoriaMetrics/VictoriaLogs/issues/1199).
 * BUGFIX: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): remove extra empty value in `Stream fields` sidebar when selecting all values within a field. See [#1235](https://github.com/VictoriaMetrics/VictoriaLogs/issues/1235).
 * BUGFIX: [web UI](https://docs.victoriametrics.com/victorialogs/querying/#web-ui): fix target log rendering in the `Log context` modal. See [#1199](https://github.com/VictoriaMetrics/VictoriaLogs/issues/1199).
