The part of Studio Client API that corresponds to CMCC's Unified API in Java (content, workflow, users) has been overhauled to provide more precise TypeScript types. Studio Client TypeScript code has been migrated from ActionScript, where it was not possible to describe callback function signatures and certain complex types (unions, intersections, generic types / type parameters). With TypeScript, now it is. To provide an improved formal description of the API, all vague types like AnyFunction or any have been replaced by more specific types, mostly already given in the textual documentation. This affects the packages @coremedia/studio-client.client-core and @coremedia/studio-client.cap-rest-client. Formally, changing the API to be more specific is a breaking change. But the required callback signatures, array element types and union types have already been documented as text, so if your code adheres these constraints, it is not going to break. Otherwise, only the TypeScript types of your code might have to be adapted, or the new, more precise types may even find hidden bugs in client code that need to be fixed.
