 1. Allows generation of [`moq`](template-moq.md)-style templates. The https://github.com/matryer/moq project is being folded into mockery to combine the speed and configuration flexibility of mockery with the simplicity of moq-style mocks.
 2. Changes the generation scheme to be entirely driven off of Go templates. This means that the data provided to templates is considered as part of the public API.

+4. Shedding all deprecated variables and simplifying the way in which mocks are configured.
