 ## tip
 
+* FEATURE: parse timestamps in [`_time` filter](https://docs.victoriametrics.com/victorialogs/logsql/#time-filter) with nanosecond precision.
 * FEATURE: return the last `N` matching logs from [`/select/logsql/query` HTTP API](https://docs.victoriametrics.com/victorialogs/querying/#querying-logs) with the maximum timestamps if `limit=N` query arg is passed to it. Previously a random subset of matching logs could be returned, which could complicate investigation of the returned logs.
 * FEATURE: add [`drop_empty_fields` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#drop_empty_fields-pipe) for dropping [log fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model) with empty values.
