NOTICE 1: Foamfix has been removed because it has been causing crashes on startup for many users. If you are not one of these users, I would recommend reinstalling it manually. Foamfix helps improve performance, but it's not as helpful if it prevents you from loading the game.
NOTICE 2: Serens Seasons config has been reset in order to take advantage of some updates to the mod. One update is that oceans will no longer freeze in winter. If your ocean is already frozen when you update the pack, the ice will not melt when summer comes. I would recommend updating in summer. Otherwise you can run the following command while standing on ice in the ocean and it will clear the ice in a 64 block radius around you:
/fill ~-64 ~-1 ~-64 ~64 ~-1 ~64 water 0 replace minecraft:ice
