no issue
- upgrade to latest `ember-source` and related dependencies including `ember-cli`
- upgrade to latest `ember-mocha` and modern ember testing setup
- https://github.com/emberjs/rfcs/blob/master/text/0268-acceptance-testing-refactor.md
- switch from using global acceptance test helpers and `native-dom-helpers` to using the new `ember-test-helpers` methods
- use [`chai-dom`](https://github.com/nathanboktae/chai-dom) assertions where in some places (still a lot of places in the tests that could use these)
- pin `ember-in-viewport` to 3.0.x to work around incompatibilities between different versions used in `ember-light-table`, `ember-infinity`, and `ember-sticky-element`
- incompatibilities manifested as "Invalid value used as weak map key" errors thrown when using `ember-light-table` (subscribers screen)
- pin `ember-power-datepicker` to unreleased version that contains a move from global acceptance test helpers to modern test helpers
no issue
- add eslint-plugin-ember, configure no-old-shims rule
- run `eslint --fix` on `app`, `lib`, `mirage`, and `tests` to move imports to the new module imports
- further cleanup of Ember globals usage
- remove event-dispatcher initializer now that `canDispatchToEventManager` is deprecated
refs TryGhost/Ghost#8455
- ensure `uploadUrls` and `errors` are cleared in `gh-uploader` when new uploads are started
- yield `isUploading` in `gh-uploader` component
- replace image upload modals in settings/general with in-page uploads
no issue
- switch `jscs` and `jshint` inline config to `eslint` config
- fix eslint errors, predominantly in tests where the config now the main app config more closely
no issue
- override `x-file-input` in `gh-file-input` to look for a custom property on the change event if we are in testing mode (this is necessary because Ember 2.5+ use native rather than jQuery events so `target.files` is readonly, see https://github.com/emberjs/ember.js/issues/13540)
- migrate unit tests for the uploader components to the integration tests
- add skipped acceptance tests for the subscribers CSV import now that it's possible to simulate file uploads
