This is the fourth patch release for JHipster 4.0.0, with 54 bug fixes and tickets closed.
We now have HTTP/2 support thanks to top hipster Matt Raible. Configuration is available in the application-*.yml files, with a new JHipsterProperties entry.
For Angular 2+ users, we used to have a jhiHasAuthority and a jhiHasAnyAuthority directives, which basically did the same thing, so now only the jhiHasAnyAuthority directive is available.
