no issue
- according to https://github.com/renovatebot/config-help/issues/220#issuecomment-487118205 it's the _last_ matching group that takes effect when determining which `packageRules` group a dependency is put in
- adjusted the order so that explicit excludes are not required and the ember-basic-dropdown addons are correctly grouped
no issue
- grouped `ember-basic-dropdown` and related `ember-power-*` addons together
- they share a common base and are going through a major breaking change so it's easier to upgrade them together
no issue
- the `config:base` preset sets a maximum of 2 PRs per hour
- we have specific timings for Renovate in this repo so the max limit is more hindrance than help
no issue
- ignore `ember-exam` until it's compatible with latest stable of `ember-mocha`
- see https://github.com/ember-cli/ember-exam/issues/238
- moved `ember-exam`, `ember-mocha`, and `testem` into their own group so changes to test env don't cause addon upgrade PRs to fail
