Changed

- Due to the new [engine cooking API](https://tartiflette.io/docs/api/engine#cook-your-tartiflette) in Tartiflette 0.12, `TartifletteApp` now includes a startup event handler responsible for building the GraphQL engine. If submounting, it **must** be registered on the parent ASGI app. Helpers in the `mount` module take care of this for you.

Removed

- Drop support for Tartiflette 0.11.x and below.
