Gutenberg 8.5 has been released. This is the last plugin release that is going to be included entirely (without experimental features) in WordPress 5.5.
Drag and Drop
Since its first introduction, the experience of drag and dropping blocks to reorder them has stayed almost untouched. This release includes several iterations to improve on this interaction. Drag and drop supports vertical reordering more clearly, it replaces the cloned element with a nice little drag chip and smooth the scroll-on-drag behavior.
