+however, forking workers for concurrent processing is a delicate process and if not done carefully
+can lead to performance degradations. It should be configured with careful consideration by advanced
+users.
+
+In v2, the automatic forking of workers has been disabled by default. This means that the Hive
+Gateway will no longer automatically create child processes to handle concurrent requests. Instead,
+you can manually configure forking if needed.
