+
+#### \[Version 0.9.2.2] EpicKnarvik97 fork
+
+- Prevents teleportation of a player holding creatures on a leash when handleLeashedCreatures is disabled, to prevent
+  players accidentally losing the creatures during teleportation
+- Fixes a potential exception when a gate's open-block or closed-block is set to a material which isn't a block
+- Fixes a potential exception when a portal without a sign has an invalid gate type
+- Prevents loading of gate files using non-blocks as part of the border
+- Prevents a player smuggling another player through a restricted stargate by sitting on a creature held in a lead by
+  the first player
+
+#### \[Version 0.9.2.1] EpicKnarvik97 fork
+
+- Makes sure to only reload whatever is necessary when config values are changed using commands, instead of reloading
+  the entire config file every time
+- Protects portals from block placement when protectEntrance is enabled
+
+#### \[Version 0.9.2.0] EpicKnarvik97 fork
+
+- Increases max length of names and networks to 13 characters
+- Excludes color codes from the counted character length to allow a colored, 13-character name
+- Makes portal names and networks case- and color-agnostic to prevent some confusion caused by typos or sloppy
+  configuration
+- Makes the free gate color configurable, and renames freeGatesGreen to freeGatesColored
+
+#### \[Version 0.9.1.2] EpicKnarvik97 fork
+
+- Allows a sneaking player to see information about a silent stargate with no sign
+
+#### \[Version 0.9.1.1] EpicKnarvik97 fork
+
+- Makes sure to translate the `&` character to fix a bug causing portal signs to not be colored on some servers

+#### \[Version 0.9.1.0] EpicKnarvik97 fork
+
+- Rewrites config loading as a part of the changes required to implement config commands
+- This update adds commands to change all config values from the chat or the console, complete with tab completion
+- Adds a new permission "stargate.admin.config" which is required to edit config values from the chat
