* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth/): add `idleConnTimeout` flag set to 50s by default. It should reduce the probability of `broken pipe` or `connection reset by peer` errors in vmauth logs.
|
||||
* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth/): add auto request retry for trivial network errors, such as `broken pipe` and `connection reset` for requests to the configured backends.
|
||||
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent/): increase default value of `-promscrape.maxDroppedTargets` command-line flag to 10_000 from 1000. This makes it easier to track down large number of dropped targets.
|
||||
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add `max_scrape_size` parameter to a scrape config for setting a custom scrape limit for a job. The new [automatically generated metric](https://docs.victoriametrics.com/vmagent/#automatically-generated-metrics) `scrape_response_size_bytes` was added to reflect the response size of the target.
|
||||
* FEATURE: [vmsingle](https://docs.victoriametrics.com/single-server-victoriametrics/): check for ranged vector arguments in non-rollup expressions when `-search.disableImplicitConversion` or `-search.logImplicitConversion` are enabled. For example, `sum(up[5m])` or `absent(up[5m])` will fail to execute if these flags are set.
|
||||
* FEATURE: [vmsingle](https://docs.victoriametrics.com/single-server-victoriametrics/): validate that rollup expressions has ranged vector arguments passed when `-search.disableImplicitConversion` or `-search.logImplicitConversion` are enabled. For example, `rate(metric)` or `count_over_time(metric)` will fail to execute if these flags are set.
|
||||
* FEATURE: [vmalert-tool](https://docs.victoriametrics.com/vmalert-tool/): support file path with hierarchical patterns and regexpes, and http url in unittest cmd-line flag `-files`, e.g. `-files="http://<some-server-addr>/path/to/rules"` or `-files="dir/**/*.yaml"`.

* `scrape_response_size_bytes` - response size in bytes for the given target. This allows to monitor amount of data scraped
|

and to adjust `max_scrape_size` for scraped targets. For example, the following [MetricsQL query](https://docs.victoriametrics.com/metricsql/)

returns targets with scrape response > 10MiB:

* `scrape_timeout_seconds` - the configured timeout for the current scrape target (aka `scrape_timeout`).

This allows detecting targets with scrape durations close to the configured scrape timeout.
