 * BUGFIX: [vmctl](https://docs.victoriametrics.com/vmctl/): drop rows that do not belong to the current series during import. The dropped rows should belong to another series whose tags are a superset of the current series. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7301) and [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7330). Thanks to @dpedu for reporting and cooperating with the test.
 * BUGFIX: [vmsingle](https://docs.victoriametrics.com/single-server-victoriametrics/), `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): keep the order of resulting time series when `limit_offset` is applied. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7068).
+* BUGFIX: [graphite](https://docs.victoriametrics.com/#graphite-render-api-usage): properly handle xFilesFactor=0 for `transformRemoveEmptySeries` function. See [this PR](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7337) for details.
