+Abstract
+========
+
+This CEP details the roadmap for planned new features and breaking changes for Celery NextGen.
+The description of these features is done in other CEPs. If one is available, we will provide a link to the matching CEP.
+Otherwise, we will link to an issue which describes the motivation behind the feature or breaking change.
+
+The document will be updated from time to time whenever we intend to release new major versions of Celery.
+

+Motivation
+==========
+
+We'd like to inform our users on which features will be released in the upcoming major versions of Celery.
+
+In addition, we would like to communicate to our technical board what's in store for Celery.
+We will create Github projects for each feature detailed in this CEP after it is accepted.
+

+=========
+
+Backwards Compatibility
+=======================
+
+There are no backwards compatibility concerns in this CEP.
+
+Reference Implementation
