@ -42,6 +42,7 @@ See also [LTS releases](https://docs.victoriametrics.com/lts-releases/).
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add `-streamAggr.dropInputLabels` command-line flag, which can be used for dropping the listed labels from input samples before applying stream [de-duplication](https://docs.victoriametrics.com/stream-aggregation/#deduplication) and aggregation. This is faster and easier to use alternative to [input_relabel_configs](https://docs.victoriametrics.com/stream-aggregation/#relabeling). See [these docs](https://docs.victoriametrics.com/stream-aggregation/#dropping-unneeded-labels).
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add `dedup_interval` option, which allows configuring individual [deduplication intervals](https://docs.victoriametrics.com/stream-aggregation/#deduplication) per each [stream aggregation config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config).
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): use the same logic in [stream deduplication](https://docs.victoriametrics.com/stream-aggregation/#deduplication) as in [the deduplication at VictoriaMetrics](https://docs.victoriametrics.com/#deduplication). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5643).
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): ignore out of order samples samples when calculating [`increase`](https://docs.victoriametrics.com/stream-aggregation/#increase), [`increase_prometheus`](https://docs.victoriametrics.com/stream-aggregation/#increase_prometheus), [`total`](https://docs.victoriametrics.com/stream-aggregation/#total) and [`total_prometheus`](https://docs.victoriametrics.com/stream-aggregation/#total_prometheus) outputs. Thanks to @edma2 for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5931).
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add `keep_metric_names` option, which can be set at [stream aggregation config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config) in order to keep the original metric names in the output aggregated samples instead of using [the default output metric naming scheme](https://docs.victoriametrics.com/stream-aggregation/#output-metric-names).
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): align the time of aggregated data flush to the specified aggregation `interval`. For example, if `interval` is set to `1m`, then the aggregated data will be flushed at the end of every minute. The alginment can be disabled by setting `no_align_flush_to_interval: true` option at [stream aggregation config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config). See [these docs](https://docs.victoriametrics.com/stream-aggregation/#flush-time-alignment) for details.
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add [unique_samples](https://docs.victoriametrics.com/stream-aggregation/#unique_samples) output, which can be used for calculating the number of unique sample values over the given `interval`.
