Previously this flag was limiting the number of concurrent connections established from clients, which send data to VictoriaMetrics. Some of these connections could be temporarily idle. Such connections do not take significant CPU and memory resources, so there is no need in limiting their count. The new logic takes into account only those connections, which **actively** ingest new data to VictoriaMetrics and to [vmagent](https://docs.victoriametrics.com/vmagent.html). This means that the default `-maxConcurrentInserts` value should handle cases, which could require increasing the value in the previous releases. So it is recommended trying to remove the explicitly set `-maxConcurrentInserts` command-line flag after upgrading to this release and verifying whether this reduces CPU and memory usage. **Update note 2:** The `vm_concurrent_addrows_current` and `vm_concurrent_addrows_capacity` metrics [exported](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#monitoring) by `vmstorage` are replaced with `vm_concurrent_insert_current` and `vm_concurrent_insert_capacity` metrics in order to be consistent with the corresponding metrics exported by `vminsert`. Please update queries in dahsboards and alerting rules with new metric names if old metric names are used there.
