## [v1.85.2](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.85.2)
Released at 19-12-2022
Released at 2022-12-19
* FEATURE: support overriding of `-search.latencyOffset` value via URL param `latency_offset` when performing requests to [/api/v1/query](https://docs.victoriametrics.com/keyConcepts.html#instant-query) and [/api/v1/query_range](https://docs.victoriametrics.com/keyConcepts.html#range-query). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3481).
* FEATURE: allow changing field names in JSON logs if VictoriaMetrics components are started with `-loggerFormat=json` command-line flags. The field names can be changed with the `-loggerJSONFields` command-line flag. For example `-loggerJSONFields=ts:timestamp,msg:message` would rename `ts` and `msg` fields on the output JSON to `timestamp` and `message` fields. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2348). Thanks to @michal-kralik for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3488).

Released at 08-04-2021
Released at 2021-04-08
* FEATURE: vminsert and vmagent: add `-sortLabels` command-line flag for sorting metric labels before pushing them to `vmstorage`. This should reduce the size of `MetricName -> internal_series_id` cache (aka `vm_cache_size_bytes{type="storage/tsid"}`) when ingesting samples for the same time series with distinct order of labels. For example, `foo{k1="v1",k2="v2"}` and `foo{k2="v2",k1="v1"}` represent a single time series. Labels sorting is disabled by default, since the majority of established exporters preserve the order of labels for the exported metrics.
* FEATURE: allow specifying label value alongside label name for the `others sum` time series returned from `topk_*` and `bottomk_*` functions from [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html). For example, `topk_avg(3, max(process_resident_memory_bytes) by (instance), "instance=other_sum")` would return top 3 series from `max(process_resident_memory_bytes) by (instance)` plus a series containing the sum of other series. The `others sum` series will have `{instance="other_sum"}` label.
