Ember-simple-auth: DEPRECATION: ember-cli-babel 5.x has been deprecated

[rinoldsimon]

After installing ember-simple-auth in an Ember project, following error appears when running the server:

DEPRECATION:ember-cli-babel 5.x has been deprecated. Please upgrade to at least ember-cli-babel 6.6.0

Environment

Ember Version: 2.18.2
Ember CLI Version: 2.18.2
ember-simple-auth Version: 1.6.0

Steps to Reproduce

In the Ember project install ember-simple-auth:

ember install ember-simple-auth

After that run an Ember command like:

ember -v

or:

ember s

Are you sure? I couldn't reproduce with Ember version 2.18.2 and ESA version: 1.6.0

Could you add a repo I could check it out on?

Because the package.json says we're using babel 6

[rinoldsimon]

this is the exact message i get when i run ember -v or ember s

DEPRECATION:ember-cli-babel 5.x has been deprecated. Please upgrade to at least ember-cli-babel 6.6. Version 5.2.8 located: project -> ember-simple-auth -> ember-cookies -> ember-getowner-polyfill -> ember-cli-babel

[geekygrappler]

This is a dependency of a dependency. ember-getowner-polyfill is still using ember-cli-babel 5.x. We can't fix it.

Out of interest, what version is the minimum version of Ember this addon is trying to support? If it's Ember 2.4, then the ember-getowner-polyfill reference can be removed altogether and at least the second of the two warnings @rinoldsimon posted will go away.

We've managed to get from 29 of these deprecation warnings down to 7, and 3 of those are from simplabs addons (ember-simple-auth and ember-cookies). It would be lovely to have no warnings :)

ESA supports Ember 1.12 (!) and up and thus needs the polyfill.

[BryanCrotaz]

then please publish a new major version (thus breaking the promise of backwards compatibility) that doesn't use the polyfill and only supports Ember 2.4 upwards
