exists.
- [x] Mention the change in the
[Changelog](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/docs/CHANGELOG.md).
Explain what has changed and why. If there is a related issue or
documentation change - link them as well.
Tips for writing a good changelog message::
* Write a human-readable changelog message that describes the problem
and solution.
* Include a link to the issue or pull request in your changelog message.
* Use specific language identifying the fix, such as an error message,
metric name, or flag name.
* Provide a link to the relevant documentation for any new features you
add or modify.
- [ ] After your pull request is merged, please add a message to the
issue with instructions for how to test the fix or try the feature you
added. Here is an
[example](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4048#issuecomment-1546453726)
- [x] Do not close the original issue before the change is released.
Please note, in some cases Github can automatically close the issue once
PR is merged. Re-open the issue in such case.
- [x] If the change somehow affects public interfaces (a new flag was
added or updated, or some behavior has changed) - add the corresponding
change to documentation.

When at least one remote write has deduplication configured it cleans up
timeseries while they can be in use by another remote write without
deduplication

The panel will show how many ongoing select queries are processed by vmstorage
and should help to identify resource bottlenecks. See panel description for more details.

Allowing to select multiple instance IPs makes it much easier to view
metrics for longer periods of time in dynamic environments such as
Kubernetes. In k8s update will also cause IP to change making it harder
to use dashboard to check the status.

The new flag type is supposed to be used for specifying URL values which
could contain sensitive information such as auth tokens in GET params or
HTTP basic authentication.
The URL flag also allows loading its value from files if `file://`
prefix is specified. As example, the new flag type was used in
app/vmbackup as it requires specifying `authKey` param for making the
snapshot.

Starting from v1.99.0 vmalert could ignore anchors pointing to specific
rule groups if `search` param was present in URL.
This change makes anchors compatible with `search` param in UI.

Using `sh` or `console` formatting doesn't do word-breaking on render. This makes flags description
harder to read, as users need to scroll the web page horizontally.
Removing the formatting renders the description with normal word-breaking.
Stream aggregation may yield inaccurate results if it processes incomplete data.
This issue can arise when data is sourced from clients that maintain a queue of unsent data, such as Prometheus or vmagent.
If the queue isn't fully cleared within the aggregation interval, only a portion of the time series may be included in that period, leading to distorted calculations.
To mitigate this we add an option to ignore first N aggregation intervals. It is expected, that client queues
will be cleared during the time while aggregation ignores first N intervals and all subsequent aggregations
will be correct.
It is better from visibility PoV if the CONTRIBUTING.md file is visible at https://docs.victoriametrics.com/contributing/ .
This page can be indexed by search engines and searched by our users later.
It is also easier to provide a link to this page now comparing to the old link, which is much harder to remember:
https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/CONTRIBUTING.md
While at it, syncrhonize docs/CONTRIBUTING.md with .github/PULL_REQUEST_TEMPLATE/pull_request_template.md ,
so they do not contain duplicate information, which can be outdated over time. Now all the relevant information
is located at docs/CONTRIBUTING.md, while .github/PULL_REQUEST_TEMPLATE/pull_request_template.md refers this doc.

This speeds up auto-suggestion for metric names in VMUI and Grafana, which use the following query in this case:
/api/v1/label/__name__/values?match[]={__name__=~"*.some_value.*"}
When the user types `some_value` in the query input field.
- Use exact matching by default for the query arg value provided via arg=value syntax at src_query_args.
Regex matching can be enabled by using =~ instead of = . For example, arg=~regex.
This ensures that the exact matching works as expected without the need to escape special regex chars.
- Add helper functions for creating QueryArg, Header and Regex structs in tests.
This improves maintainability of the tests.
- Remove url.QueryUnescape() call on the url in TestCreateTargetURLSuccess(), since this is bogus approach.
The url.QueryUnescape() must be applied to individual query args, and it mustn't be applied to the whole url,
since in this case it may perform invalid unescaping in the context of the url, or make the resulting url invalid.
While at it, properly marshal all the fields inside UserInfo config to yaml in tests.
Previously Header and QueryArg structs were improperly marshaled because the custom MarshalYAML
is called only on pointers to Header and QueryArg structs. This improves test coverage.

If one out of 10 vmstorage nodes is unavailable, then the remaining 9 vmstorage nodes will receive 1/10=10% increase of workload, not 1%.

* app/vmauth: do not increment backend_errors when hitting concurrency limit
Previously, both "vmauth_concurrent_requests_limit_reached_total" and "vmauth_user_request_backend_errors_total" were incremented.
This was based on the assumption that if concurrency limit is hit the backend must be failing to handle the request thus meaning an error.
This assumption does not work in case the endpoint can be overloaded by the misbehaving client sending too many requests within the timeframe.
