+  * ## [v0.50.0 [2023/06/27]](#v0.50.0[2023/06/27])
+    * ### Notes
+     > For enhanced security, the default values for tls_enable and disable_custom_tls_first_byte have been set to true.If you wish to revert to the previous default values, you need to manually set the values of these two parameters to false.
+
+    * ### Features
+     > Added support for allow_users in stcp, sudp, xtcp. By default, only the same user is allowed to access. Use * to allow access from any user. The visitor configuration now supports server_user to connect to proxies of other users.
+     
+     > Added fallback support to a specified alternative visitor when xtcp connection fails.
+
+    * ### Improvements
+     > Increased the default value of MaxStreamWindowSize for yamux to 6MB, improving traffic forwarding rate in high-latency scenarios.
+
+    * ### Fixes
+
+     > Fixed an issue where having proxies with the same name would cause previously working proxies to become ineffective in xtcp.
