What’s new in Gutenberg? (May the 4th)

Things are going well on the road towards completing the first phase of the editor project. Most of the work is centered around polish, getting things ready for merge, and tightening existing APIs. CloudupBlogLoginAboutBlogFaqTermsPrivacy
This release has many refinements and improves the capabilities of the Block and Plugin APIs. It also adds a new “spacer” block for generating visual space. The color palette component has been improved to be based on classes instead of inline styles (for registered colors) and includes some important accessibility improvements (like naming the color). Thank you to everyone involved!
2.8
Add a pasting schema in raw content handling. It simplifies whitelisting and reduces the amount of filters run. Should improve reliability, clarity, markdown conversion, and usage in blocks.
Add “Spacer” block to create empty areas.
Expand public InnerBlocks API with support for template configuration and allowedBlocks logic.
ColorPalette improvements:
Implement mechanism to use classes for configured colors instead of inline styles. Use it in Button block as well.
Use color name in ColorPalette aria-label for making color selection more accessible.
