1.0.0 [202x.xx.xx]

The first stable. It will be a product that I expect other people to use for important projects, therefore backwards compatibility will be important. The whole system needs extensive testing in real applications. Much of this will be done in the development of the core libraries. We will also need to add handling for several very different languages (proofs-of-concept).

• typeclasses
• semantic types - test in bioinformatics applications
• constraints - refined types?
• manifold hooks - caching, documentation, logging, effects
• logic engine (z3?) - from typechecking to architecture design and debugging
• ecosystem (test suite, linter, package tools, vim plugin)
• language support (Python3, R, C++, Java, Haskell, Scheme, Prolog)
• well tested core libraries

0.26.0 [2020.09.27]

No explicit forall. Instead use Haskell convention of generics being lowercase and non-generics being uppercase.

• no more explicit "forall"
• generics are lowercase in type signatures
• non-generic types are uppercase
• normal functions are lowercase
• class constructors are uppercase (though handling for this is not yet implemented)

0.24.0 [2020.09.22]

Allow integration of many instances

0.23.0 [2020.05.14]
