The latest version (0.7.9) has an updated Forge version if you want to use that, but that's only available on Technic.How would i update the forge?
To do it for the ftb launcher you have to change the Forge version in the pack.json or version.json (I forgot the name). However, you would also have to update Forge for the server as well. Currently I'm on mobile, but I'll write up a small guide on how to do it when I get to my computer.
