In the old version, you could download the water effects for rivers, springs, puddles, etc. If you want to download the water effects for seas, then you need to download the ocean effects. Now you can combine both of them in one download.

I just thought that they could use a little bit of attention and make them more complimentory to my Splash and Weather mods.

This is an important update because it has a lot of changes. You can combine the two mods into one and use them in your game. The reason why I did this is that the two mods work together. You need to download them both and use them.
