A new version of Gutenberg was released. It will be part of WordPress 5.2.1, which is close to a first release candidate. Improvements to Gutenberg include the ability to set different widths for each column in the columns blocks, improved usability of the group and columns blocks, accessibility fixes, and key “writing flow” bug fixes.
Do you want your sites in a multisite network to share reusable Gutenberg blocks in a “hub-and-spoke style?” Richard Tape has a plugin for that. 🎡
