Most people who are interested in news about WordPress are quite curious about the new version (5.0.0) together with the new default theme (Twenty Nineteen). In just a few words: together with the Gutenberg editor, this new version is supposed to come as competition to the more and more popular SaaS tools for building websites yourself (e.g. Wix).
Download and install Peter Westwood's Beta Tester Plugin – you can do it via the normal plugin install.
Activate Twenty Nineteen and play with it.
