Minor Changes

• With the "single-source behavior" the Client will now also avoid executing an operation if it's already active, has a previous result available, and is either run with the cache-first or cache-only request policies. This is similar to a "short circuiting" behavior, where unnecessary work is avoided by not issuing more operations into the exchange pipeline than expected, by @kitten (See #1600)
• Add consistent "single-source behavior" which makes the Client more forgiving when duplicate
  sources are used, which previously made it difficult to use the same operation across an app
  together with cache-and-network; This was a rare use-case, and it isn't recommended to overfetch
  data across an app, however, the new Client implementation of shared sources ensures that when an
  operation is active that the Client distributes the last known result for the active operation to
  any new usages of it (which is called “replaying stale results”) (See #1515)

Patch Changes

• Remove closure-compiler from the build step (See #1570)
• ⚠️ Fix inconsistency in generating keys for DocumentNodes, especially when using GraphQL Code Generator, which could cause SSR serialization to fail, by @zenflow (See #1509)
