 # Changes
 
+#### \[Version 0.11.5.12] Unified Legacy Fork
+
+- Fixes gate verification incorrectly treating valid Stargates as invalid
+- Improves the default permissions of players to allow personal creation of standard nether stargates, and general
+  Stargate use.
+- Adds three new permission groups for easier permission setup: stargate.group.admin, stargate.group.builder,
+  stargate.group.player. The builder group allows creation and destruction of all Stargates, and usage of all
+  options/flags except bungee portals.
+- Fixes end gateways not teleporting players unless sneaking into the portal on newer Minecraft versions.
+- Adds an error message in case Stargate detects some other plugin cancelled or interfered with its teleportation.
+- Stops some debug output during startup when debug is disabled
+- Renames the silent option to quiet internally to better match the Q character used to enable the option.
+- Replaces code for message formatting
+- Improves some error messages
+- Replaces some code with KnarLib implementations
+- Updates some dependencies
+- Restructures all event code, and improves Stargate protection
+- Removes static permission strings, and removes redundancy in permission checking code
