- Move out main modules from `lib` folder - Introduce `normalizer` based configurations, and convert primitive and regular handlers into thos normalizers (can be found in lib/normalizers folder). Custom normalizers can be provided at run time via `normaizer` option - Provide `plain` module which does not load any extensions or normalizers. Any extensions that have to be used should be required upfront and normalizers should be provided directly - Remove `method` option, instead `methods` and `methods-plan` modules are provided which generate descriptors for lazy created memoized methods - `profile` is no longer extension. To be used it should be required directly - Improve logic for `async` handling - Take out `max` extensionLRU logic into external `lru-queue` package - Remove `context` option - Remove possibility to access original arguments when resolvers are used - Assure expected length of memoized functions
