 ## tip
 
 
+* FEATURE: take into account failed queries in `vm_request_duration_seconds` summary. Previously only successful queries were taken into account. This could result in skewed summary. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1537).

 ## [v1.64.1](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.64.1)
 
 * FEATURE: add `bitmap_and(q, mask)`, `bitmap_or(q, mask)` and `bitmak_xor(q, mask)` functions to [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html). These functions allow performing bitwise operations over data points in time series. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1541).
