Problem/Motivation
Ctools 3.8.0 and up introduced a breaking change to the Content Entity Field module that causes Drupal to think that the entity_field:node plugin no longer exists.
Full error output:
The website encountered an unexpected error. Please try again later.

Steps to reproduce
- Have a drupal site with Ctools, context, and the context entity field modules enabled and in use (plus other dependencies).
- Create and use a entity field context
- Observe white screen error (see above) that breaks entire site, including admin side.
Proposed resolution
Ctools has marked the following class as deprecated: Drupal\ctools\Plugin\Deriver\EntityBundle; the class Drupal\Core\Entity\Plugin\Condition\Deriver\EntityBundle should be used instead. When updating this class, site no longer white screens and context entity field works again.
Remaining tasks
User interface changes
API changes
Data model changes
