v7.0.0 - Construct all the things!

Features:

• add more constructor helpers for dealing also with abstract constructors: Constructor already exists for non-abstract classes, the AbstractConstructor type is added for abstract classes,
  and the AnyConstructor type is added for representing both.

BREAKING:

We also updated the TypeScript version. You might not need to do anything, but knowing TypeScript there's a bigger chance compared to with other tools that something broke because they don't follow the semver versioning rules established in the JavaScript community.
