[dependabot-preview]

Bumps apollo-client from 2.5.1 to 2.6.3.

Changelog

Sourced from apollo-client's changelog.

Apollo Client (2.6.3)

Apollo Client (2.6.3)

• A new ObservableQuery.resetQueryStoreErrors() method is now available that
  can be used to clear out ObservableQuery query store errors.
  
  @​hwillson in #4941
• Documentation updates.
  
  [@​michael-watson](https://github.com/michael-watson) in #4940
  
  @​hwillson in #4969

Apollo Client (2.6.1)

Apollo Utilities 1.3.2

• Reimplement isEqual without pulling in massive lodash.isequal.
  
  @​benjamn in #4924

Apollo Client (2.6.1)

• In all Apollo Client packages, the compilation of lib/bundle.esm.js to lib/bundle.cjs.js and lib/bundle.umd.js now uses Babel instead of Rollup, since Babel correctly compiles some edge cases that neither Rollup nor TypeScript compile correctly.
  
  @​benjamn in #4911

Apollo Cache In-Memory 1.6.1

• Pretend that __typename exists on the root Query when matching fragments.
  
  @​benjamn in #4853

Apollo Utilities 1.3.1

• The isEqual function has been reimplemented using the lodash.isequal npm package, to better support circular references. Since the lodash.isequal package is already used by react-apollo, this change is likely to decrease total bundle size.
  
  @​capaj in #4915

Apollo Client (2.6.0)

• In production, invariant(condition, message) failures will now include
  a unique error code that can be used to trace the error back to the
  point of failure.
  
  @​benjamn in #4521

Apollo Client 2.6.0

• If you can be sure your application code does not modify cache result objects (see freezeResults note below), you can unlock substantial performance improvements by communicating this assumption via

  new ApolloClient({ assumeImmutableResults: true })

  which allows the client to avoid taking defensive snapshots of past results using cloneDeep, as explained by @​benjamn in #4543.

• Identical overlapping queries are now deduplicated internally by apollo-client, rather than using the apollo-link-dedup package.
