 This fork is designed for keeping your old servers in your network, until your modspacks are available for 1.12.2/1.14.4 or higher.
 Most of them are, so get rid of 1.7 fast and move to 1.12.2 or even newer modpacks asap.
 
+PLEASE: Only use this fork if really needed.(1.7 legacy servers.) If you dont need 1.7 or Sponge support, grab original BungeeCord. Link is above.
