v2.0.0

Note: The minimum required version of urql for this release is now 1.7.0!

Christmas came early! This version improves performance again by about 25% over 1.2.2. It also now ships with two new features: The populateExchange and automatic garbage collection.

Including the populateExchange is optional. It records all fragments in any active queries, and populates mutation selection sets when the @populate directive is used based on typenames. If your
schema includes viewer fields on mutations, which resolve back to your Query type, you can use this to automatically update your app's data when a mutation is made. (More documentation on this
is coming soon!)

The garbage collection works by utilising an automatic reference counting algorithm rather than a mark & sweep algorithm. We feel this is the best tradeoff to maintain good performance during runtime while minimising the data that is unnecessarily retained in-memory. You don't have to do anything! Graphcache will do its newly added magic in the background.

There are some breaking changes, if you're using cache.resolveConnections or resolveValueOrLink then you now need to use inspectFields and resolveFieldByKey instead. You may also now make use of cache.keyOfField. (More info on #128)
