Gutenberg 3.7 is available for download and contains a number of changes. The Fixed Toolbar has been renamed Unified Toolbar. This is an optional mode that fixes all of the toolbar icons to the top of the editor, similar to the Classic editor.

The team discovered that experienced users who don’t mind the disconnect between blocks and the toolbar preferred this layout.

There’s now an animation and icon specifically tailored for the Block Converter action. Hovering the cursor over a block’s icon will display two arrows that represent the ability to change block types.

For those who want to focus on one block of content at a time, there’s a new mode called Spotlight. When enabled, the blocks that are not being edited partially fade away and the block outlines disappear. This is an experimental attempt at introducing a Distraction Free Writing mode.

The icons have been updated for Paragraph, Heading, and Subheading blocks to add clarity. Previous to 3.7, the Paragraph block icon looked like an alignment option causing confusion.
