 #### Backwards compatability changes
 #### Backwards compatability changes
 - When eager-loading a many-to-many association, the attributes of the through table are now accessible through an attribute named after the through model rather than the through table name singularized. i.e. `Task.find({include: Worker})` where the table name for through model `TaskWorker` is `TableTaskWorkers` used to produce `{ Worker: { ..., TableTaskWorker: {...} } }`. It now produces `{ Worker: { ..., TaskWorker: {...} } }`. Does not affect models where table name is auto-defined by Sequelize, or where table name is model name pluralized.
