- Sync the description for -httpListenAddr.useProxyProtocol command-line flag at vmagent and vmauth,
  so it is consistent with the description at vmauth and victoria-metrics
- Add a sample of panic text to docs/CHANGELOG.md, so it could be googled
- Mention the -httpListenAddr.useProxyProtocol command-line flag in the description for the bugfix

@ -24,7 +24,7 @@ The following tip changes can be tested by building VictoriaMetrics components f
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): stop showing `Please enter a valid Query and execute it` error message on the first load of vmui.
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): properly process `Run in VMUI` button click in [VictoriaMetrics datasource plugin for Grafana](https://github.com/VictoriaMetrics/grafana-datasource).

* BUGFIX: [vmauth](https://docs.victoriametrics.com/vmauth.html) fixes possible panic with enabled proxy-protocol. It was introduced at [v1.87.0](https://docs.victoriametrics.com/CHANGELOG.html#v1870) when implementing [this feature](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3335).
* BUGFIX: [vmauth](https://docs.victoriametrics.com/vmauth.html): fix `cannot serve http` panic when plain HTTP request is sent to `vmauth` configured to accept requests over [proxy protocol](https://www.haproxy.org/download/2.3/doc/proxy-protocol.txt)-encoded request (e.g. when `vmauth` runs with `-httpListenAddr.useProxyProtocol` command-line flag). The issue has been introduced at [v1.87.0](https://docs.victoriametrics.com/CHANGELOG.html#v1870) when implementing [this feature](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3335).
