Prettier for HTML Permalink to "Prettier for HTML"

We have enabled Prettier for HTML. You can run Prettier with html enabled before upgrading and commit changes to Git to see real changes in HTML files after upgrade.

Translation directive change in Angular client Permalink to "Translation directive change in Angular client"

We have moved jhiTranslate directive from ng-jhipster to generated application. If you have different jhiPrefix than jhi then you may want to replace all jhiTranslate with yourprefixTranslate and commit changes to Git before upgrade to reduce changes shown after upgrade.

Files renamed in Angular client Permalink to "Files renamed in Angular client"

In Angular client a lot of files renamed and tests moved next to files they are testing.

In manual upgrade instructions page is section Hints about renamed files - this can help in upgrading.

If the previous hint did not give a satisfactory result then you can do before upgrade:

  • move renamed files to their final location
  • commit changes after that
