v3.12.0

Minor Changes

Data masking 🎭

• #12042 1c0ecbf Thanks @jerelmiller! - Introduces data masking in Apollo Client.

  Data masking enforces that only the fields requested by the query or fragment is available to that component. Data masking is best paired with colocated fragments.

  To enable data masking in Apollo Client, set the dataMasking option to true.

  new ApolloClient({
    dataMasking: true,
    // ... other options
  });

  For detailed information on data masking, including how to incrementally adopt it in an existing applications, see the data masking documentation.
