There's a missing dot in the update checker. It says: "Vault 15.6 is out! You're running 15.5." While it should be "Vault 1.5.6 is out! You're running 1.5.5."

This seems intentional. https://github.com/MilkBowl/Vault/blob/master/src/net/milkbowl/vault/Vault.java#L129

Seems like, but it's kinda weird to say 15.5 and 15.6, it would be better to have the dot there, so we actually know the real version.

yah, it's just a formatting issue related to the checker logic. since it's just cosmetic I'm not really woried about it.

Would you fix it if I made a pr for it?

sure!
