 **Update notes:** this release introduces backwards-incompatible changes to communication protocol between `vmselect` and `vmstorage` nodes in cluster version of VictoriaMetrics because of added [query tracing](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#query-tracing), so `vmselect` and `vmstorage` nodes may log communication errors during the upgrade. These errors should stop after all the `vmselect` and `vmstorage` nodes are updated to new release. It is safe to downgrade to previous releases.
 
 * SECURITY: add `-flagsAuthKey` command-line flag for protecting `/flags` endpoint from unauthorized access. Though this endpoint already hides values for command-line flags with `key` and `password` substrings in their names, other sensitive information could be exposed there. See [This issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2753).
