> As part of the 2.0 release we deprecated a number of different internal components (one of the largest ones being the old accumulator API), and also upgraded our default build to Scala 2.11.
> This has added a large number of deprecation warnings (internal and external) - some of which can be worked around - and some of which can't (mostly in the Scala 2.10 -> 2.11 reflection API and various tests).
> We should attempt to limit the number of warnings in our build so that we can notice new ones and thoughtfully consider if they are warranted.
