Sourced from apollo-server-express's changelog.

v3.0.2

• apollo-server-types: TypeScript typings for info.cacheControl are now added to GraphQLResolveInfo as part of apollo-server-types rather than a nested file in apollo-server-core, and the field now has a named type, ResolveInfoCacheControl. [PR #5512](apollographql/apollo-server#5512)
• apollo-server-micro: Like the other framework integrations, only serve landing pages from the GraphQL path (/graphql by default, configurable via the path option to createHandler). [PR #5516](apollographql/apollo-server#5516)
• apollo-server-env: Remove polyfills of Object.values, Object.entries, and util.promisify which were only required for Node 6 support. Remove ValueOrPromise and WithRequired TypeScript types that are also provided by apollo-server-types. [PR #5515](apollographql/apollo-server#5515)

v3.0.1

• apollo-server-core: The default maxAge (which defaults to 0) for a field should only be applied if no dynamic cache control hint is set. Specifically, if you call the (new in 3.0.0) function info.cacheControl.cacheHint.restrict({ maxAge: 60 }), it should set maxAge to 60 even if the default max age is lower. (This bug fix is the behavior that was intended for 3.0.0, and primarily affects the behavior of functions added in Apollo Server 3. This does mean that checking info.cacheControl.cacheHint now only shows explicitly-set maxAge and not the default, but this seems like it will be helpful since it lets you differentiate between the two similar circumstances.) [PR #5492](apollographql/apollo-server#5492)
• apollo-server-lambda: Fix TypeScript types for context function. (In 3.0.0, the TS types for the context function were accidentally inherited from apollo-server-express instead of using the correct Lambda-specific types). [PR #5481](apollographql/apollo-server#5481)
• apollo-server-lambda, apollo-server-cloud-functions: Make the default URL path for handling GraphQL be / (ie, handle all requests). This is similar to how these packages work in Apollo Server 2. After this change, apollo-server and the serverless integrations have a default URL path of / (or ignore the path entirely, in the case of apollo-server-azure-functions), and the framework integrations have a default URL path of /graphql. This is a backwards-incompatible change from 3.0.1 but minimizes the changes from Apollo Server 2 (and this AS3 change was not intended or documented). [PR #5497](apollographql/apollo-server#5497) [Issue #5462](apollographql/apollo-server#5462)

v3.0.0

BREAKING CHANGES

Apollo Server 3 contains quite a few breaking changes. Read our migration guide for more details on how to update your app.

Bumped dependencies

The minimum versions of these dependencies have been bumped to provide an improved foundation for the development of future features.

• Dropped support for Node.js v6, v8 and v10. Apollo Server 3.x is being compiled to ES2020, which maps to Node.js 12+.
  • Note also that we only test Apollo Server on even-numbered versions of Node.js, and we only aim to support Node.js versions that are under long-term support from the Node.js Foundation.
• Dropped support for versions of the graphql library prior to 15.3.0.
• The mocks option of the ApolloServer constructor now uses @graphql-tools/mock v7 instead of graphql-tools v4, which causes some breaking changes.
  • For example, mock functions no longer receive arguments and cannot return Promises.
  • Note that some parts of the v7 migration guide suggest using the resolvers argument to addMocksToSchema. Apollo Server does not support this option, but you can call addMocksToSchema yourself and pass the result to the schema option of the ApolloServer constructor.

Removed functionality

Certain undersupported and underused Apollo Server features have been removed in favor of current or future methods for achieving similar functionality. Many of these features can be manually re-enabled, as listed below.

• Dropped built-in partial support for subscriptions via the subscriptions-transport-ws package.
  • This integration did not support many Apollo Server features, and subscriptions-transport-ws has not been actively maintained.
  • To re-enable subscriptions in Apollo Server 3 as they're supported in v2, see the migration guide.
  • We hope to provide more deeply integrated subscription support in a future release.
• Dropped built-in support for file uploads via the graphql-upload package.
  • To re-enable file uploads in Apollo Server 3 as they're supported in v2, see the migration guide.
• Dropped support for the graphql-extensions API (e.g., GraphQLExtensions, extensions) in favor of the Apollo Server plugins API.
• Dropped support for passing the schemaDirectives option to the ApolloServer constructor.

  • This option was passed directly to the graphql-tools function makeExecutableSchema. To continue using it, you can import makeExecutableSchema from @graphql-tools/schema and call it yourself:

    new ApolloServer({
      schema: makeExecutableSchema({
        typeDefs,
        resolvers,
        schemaDirectives
      })
