no issue
Since `ember-moment@10.0` it's not been necessary to use the `ember-cli-moment-shim` package, with `moment` instead being usable directly via `ember-auto-import`. Getting rid of the shim package is necessary for compatibility with `embroider`, Ember's new build tooling.
- dropped `ember-cli-moment-shim` dependency
- added `moment-timezone` dependency and updated all imports to reflect the different package
- worked around `ember-power-calendar` having `ember-cli-moment-shim` as a sub-dependency
- added empty in-repo-addon `ember-power-calendar-moment` to avoid `ember-power-calendar` complaining about a missing package
- added `ember-power-calendar-utils` in-repo-addon that is a copy of `ember-power-calendar-moment` but without the build-time renaming of the tree for better compatibility with embroider
no issue
- part of ember upgrades
- removed all unnecessary usage of `.get`
- cleaned up imports where we had imports from the same module across multiple lines
- standardized on importing specific computed helpers rather than using `computed.foo`
- switched tests from using `wait()` to `settled()`
no issue
- adds `whats-new` service that fetches the changelog from ghost.org and exposes the latest changelog entries
- trigger a background fetch of the changelog from ghost.org when first loading the admin when logged in, or after signing in
- adds a "What's new" menu item next to the user popup menu
- adds an indicator to the user menu button and what's new menu item if there are unseen changelog entries
- closing the changelog modal will update the "last seen date", clearing both indicators
