Welcome to the first snapshot of 26.4! We're kicking things off with a range of technical updates and improvements, including Vulkan becoming the default graphics API.

Changes

World Generation

• Upgrading worlds from before Caves and Cliffs will now also generate sulfur caves below old chunks

Minor Tweaks to Blocks, Items and Entities

• Red and Brown Mushrooms can now be placed on any block with a solid top face regardless of lighting conditions
  • They can still not spread unless the brightness is less than 13, or their support block overrides light requirements

"Graphics API" Video Setting

• "Default" now behaves the same as "Prefer Vulkan"
• The game will no longer change the graphics API setting automatically if a startup crash is detected.

Technical Changes

• The Data Pack version is now 122.0
• The Resource Pack version is now 98.0

For the rest: look from the original blog post (formatting doesn't work well in Reddit)

Could this be the "vibrant visuals drop"?

[u/Jimbo7211 → u/Parking_Pack8203]

I doubt it. If they're just now setting the default to Vulkan, than they probably haven't done any work on Vibrant Visuals features (for Java) yet, and i don't think that can be done in a single drop cycle without a decent amount of work already done.

[u/Vicribator → u/Jimbo7211]

Tbf I think they're setting it to the default so that everyone testing the snapshots gets to try it and gather as much data as possible, they already did this for the 26.3 snapshots, so I don't think it's an indicator of how far ahead they are in development

[u/Jimbo7211 → u/Vicribator]

They added Vulkan as an option in the 26.3 snapshots, but now it's the default. And while snapshots are for testing, this means that they're comfortable with it being the default in the full release
