@redbmk Can you please add a changelog at the bottom with a link to this PR (and the example app's PR) so people can see what changed? For example, see https://developer.okta.com/blog/2019/06/24/ionic-4-angular-spring-boot-jhipster#changelog. <-- You'll have to scroll up a bit after the page loads.

@mraible sure - I just added one. I hadn't used the <a name in markdown before but apparently that's how you can make the #changelog url work without it being a header.

I also didn't add anything about the example changing because it's a result of a few PRs and some direct commits. Lemme know if I should mention that though.
