The goal of the roadmap is to document areas the mypy core team is planning to work on in the future or is currently working on. PRs targeting these areas are very welcome, but please check first with a core team member that nobody else is working on the same thing.
Note: This doesn’t include everything that the core team will work on, and everything is subject to change.
Continue making error messages more useful and informative. (issue)
Refactor and simplify specific tricky parts of mypy internals, such as the conditional type binder, symbol tables or the various semantic analysis passes.
Invest some effort into systematically filling in missing annotations and stubs in typeshed, with focus on features heavily used at Dropbox. Better support for ORMs will be a separate project.
Make the mypy plugin architecture more general and officially supported. It should be able to support some typical ORM features at least, such as metaclasses that add methods with automatically inferred signatures and complex descriptors such as those used by Django models. (issue)
Implement editor plugins and/or document how to integrate mypy with popular editors. Support selected IDE features.
