Release

v1.1.0-alpha.3 pre-release cleans up some outstanding issues found in in alpha.2.

Other than a number of minor fixes and cleanups (thank you for all of the feedback!), the primary change in this pre-release is the fixing of incentives to preserve the intended base_reward invariant (#2266). Huge shout-out to @barnabemonnot for modeling the incentives and identifying a minor error in the specification.
