* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth.html): automatically retry failing `GET` requests on all [the configured backends](https://docs.victoriametrics.com/vmauth.html#load-balancing). Previously the backend error has been immediately returned to the client without retrying the request on the remaining backends.
* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth.html): choose the backend with the minimum number of concurrently executed requests [among the configured backends](https://docs.victoriametrics.com/vmauth.html#load-balancing) in a round-robin manner for serving the incoming requests. This allows spreading the load among backends more evenly, while improving the response time.
* FEATURE: [vmalert enterprise](https://docs.victoriametrics.com/vmalert.html): add ability to read alerting and recording rules from S3, GCS or S3-compatible object storage. See [these docs](https://docs.victoriametrics.com/vmalert.html#reading-rules-from-object-storage).
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): add `mad_over_time(m[d])` function for calculating the [median absolute deviation](https://en.wikipedia.org/wiki/Median_absolute_deviation) over raw samples on the lookbehind window `d`. See [this feature request](https://github.com/prometheus/prometheus/issues/5514).
