Major Changes:
ModInitialisers must now have a S2C sync ServerPlayConnectionEvents.JOIN.register after all config registrations, look at the serpentine mod initialiser for it.
expect() now has 3 inputs:
Key - (string) the entry's key [was already in 1.7.0] DefaultValue - (Object) the fallback value if it is unable to find it [was already in 1.7.0] Side - (SyncSide) which type of entry should it be [new in 2.0.0]
SyncSide is a new protected struct inside of the Config class, is has: SERVER_ONLY - the expect entry will only be editable on a server by an opped user. CLIENT_ONLY - the expect entry will only be seen by the user, no server can touch it. SYNCED - the expect entry will be read-only, even to opped users. Can only be edited on the host machine's scnf file.
Upgrade Instructions:
- Mark server-only fields as SyncSide.SERVER_ONLY and client-only fields as SyncSide.CLIENT_ONLY.
- Add applyServerEdit method, example here
