Minecraft Update Aquatic: Jebs PC Gamer talk.

A lot of things are happening right now in the offices of Minecraft. Nintendo Switch Bedrock, Update Aquatic, and lots of new things. But Jeb did a talk over the weekend about the current Update Aquatic things.

Dolphins

Jeb said that dolphins will follow you in a boat. If you feed it to fish it will guide you to treasure. This will more than likely be linked to shipwrecks so it will be easier to find good loot.
Dolphins can also jump as well.They will also play with the items which float on the surface of the water. This means you can play with dolphins yay.
You can also hold onto the dolphin's fin and they will bring you to treasure under the sea as well. This sounds really cool to do!
Dolphins also have the same behaviour as wolves as in if you attack one, the surrounding ones will attack you.

Phantom

Jeb also gave some info on the phantom.
He said that some people said that it had an ender feel so they changed its eyes to green.
He also said that with the phantoms spawning in the end, once you are in the end there is no way of making them stop spawning so they are currently brainstorming new ideas to make it better.

Water mechanics, coral slabs, ocean biomes, shipwrecks and bubble collums

Jeb said that if you a stair block is placed on flowing water, it will block the flow but you can put it on a source block so it both has a stair and a source block.
He also said that only full blocks will spawn in the ocean for the coral and the slabs will be craftable through the new blocks.
There will be 3 ocean biomes: warm, normal and cold. Kelp will grow in the cold biomes and the coral will spawn in the warm biomes while seagrass will spawn in all biomes.

Here was our first look at shipwrecks from Minecon 2017.

Shipwrecks will spawn with stripped logs as the masts. It will contain a special treasure.
As with the magma blocks and soul sand bubble columns, they are still brainstorming ideas.

Here is a concept art someone made for the fish in a bucket.

ow the game is made

They plan for 2 major releases each year. One is the Update Aquatic and another one is planned for later this year. This should be on all platforms.
They do the features in 2 offices. One in the Stockholm office where the Java team do their work and the other office is the Redmond office where the Bedrock (Mobile, PC, and New Console version) developers work.
They try to split the feature development and then port them both ways.

UPDATE 22nd February 2018:

A youtuber ibxtoycat released audio of the talk!

Jeb confirms that they are trying to get it out on all platforms soon(TM). Not other news than that.
Jeb then confirms that more stone typed blocks will get half slabs. But they will only be craftable. Not found naturally.
There will be no baby phantoms but you can use commands to make it bigger so that makes it a hidden feature.
You will not be able to tame phantoms.
There will be at least 1 new mob in every update.
There will be 1 theme and 1 biome focus in each update.
Villagers class a door and a block as a house due to lag and they expected people to make more houses but that didn't happen.

Thank you to Mihro for the audio and ibxtoycat for allowing me to include the information.
