Version 2.5.3 is a maintenance release with improvements around codegen, runtime and cache.
Interfaces on interfaces
Version 2.5.3 adds support for GraphQL RFC 373 (interfaces implementing interfaces). This makes sure the codegen understands interfaces implementing other interfaces and can compute the fragments possible types appropriately. It doesn't change the generated code.
Json Content-Type
Version 2.5.3 changes the Content-Type for apollo-runtime-kotlin from "aplication/json; charset=utf-8" to "application/json". This has been confusing spring servers and is the default json content type moving forward. If everything goes well, apollo-runtime will also switch to "application/json" in a future release. Read more in #2883. Many thanks to @vikrama for diving into this and fixing it.
