   Thanks to @yincongcyincong for [the pull request](https://github.com/VictoriaMetrics/victorialogs-datasource/pull/69).
 
 * BUGFIX: correctly pass time range filter when querying variable values. Before, time filter wasn't applied for `/field_values` and `/field_names` API calls. See [this](https://github.com/VictoriaMetrics/victorialogs-datasource/issues/71) and [this](https://github.com/VictoriaMetrics/victorialogs-datasource/issues/72) issues.
-* BUGFIX: fix the issue of collecting labels in different log lines. Removed duplicated labels from previous log lines. See [this issue](https://github.com/VictoriaMetrics/victorialogs-datasource/issues/60). 
+* BUGFIX: fix the issue with displaying incorrect subfields when requesting logs with different set of fields. See [this issue](https://github.com/VictoriaMetrics/victorialogs-datasource/issues/60).
