V4-migration-tslint warns about tabs in brand new project


I am migrating my v3 project by using the recommended method of installing v4 (also updated Node & npm), starting a brand new project and then copying items little by little into the new project. When using the tslint, it helpfully shows what to fix in the first old page that I copied. However, it also complains:

WARNING: (…)/src/app/tabs/tabs.page.html:1:2 - Tabs have gone through a significant refactor.
Please see https://github.com/ionic-team/ionic/blob/master/CHANGELOG.md#angular-tabs

But I started this v4 project using “ionic start myApp tabs” so the tabs were created by the CLI, I haven’t touched tab files it created. So is the CLI still generating old tab code? Thanks.
