JHipster release 4.9.0

What's new​

This new release has 66 closed tickets and merged pull requests, here are the most important news:

  • Traefik support was added last week, see #6397. It is still in BETA, but adds an interesting alternative in our microservice architecture.
  • Major improvement on JHipster UAA: Access/Refresh Token Handling for UAA Authentication #5752
  • Front-end tests will now use Chromium headless, which is a huge change: Replace PhantomJS by chromiumHeadless and puppeteer #6377
  • The Gradle Wrapper is now using the latest Gradle 4.2 release: see #6392
  • Karma tests now have source maps: this will make them a bit slower, but a lot easier to debug - see #6400
  • Issues with our AWS sub-generator should at least be fixed thanks to #6408
  • A new polyfill has been added to add IE 11 support, see #6337
  • Upgrades to Yarn, NodeJS, NPM have been made in #6424

As a result of those latest changes and bug fixes, we have removed the BETA tag on JHipster UAA and on our Kafka support option.

Warning Big changes in the OAuth2 support will happen in the next release, see #6361:

  • We will migrate from our current home-made OAuth2 support (based on Spring Security OAuth2) to use OpenID Connect
  • As a result, JHipster will work with OpenID Connect providers like Keycloak or Okta
  • This will remove a lot of code, and provide better quality and features
  • As the current OAuth2 code is used by less than 1% of projects, we feel that this change will not affect many people

How to upgrade​

And then run the upgrade sub-generator:

jhipster upgrade

Manual upgrades

For a manual upgrade, first upgrade your version of JHipster with:

yarn global upgrade generator-jhipster

If you have an existing project, it will still use the JHipster version with which it was generated. To upgrade your project, you must first delete its node_modules folder and then run:

You can also update your entities one-by-one by running again the entity sub-generator, for example if your entity is named Foo
