🛤️ tracking: EmberData 6.0 Roadmap

[runspired]

6.0 Roadmap

Target Date: Fall 2023

Overview

The EmberData Team intends to release a major version of the library around/during the summer of 2023. This issue tracks the work to be done to prepare for that major.

This major version will focus on refining the library for the Polaris Edition by building on the work delivered in 5.0

1. Removal of most remaining support for Ember classic (some bare minimum support may remain until Ember similarly deprecates support)
2. Completing the decoupling of EmberData from Ember the framework
3. Introduction of a model-optional default story for presenting data in applications

Action Items

This is a non-comprehensive list that we expect to grow over the next several months as we determine the exact mechanics of achieving the above.
