v4.0.0

⚠️ This release contains a number of breaking changes:

• cheap-ruler is now published as a ES module and no longer supports CommonJS environments.
• Switched to first-class TypeScript types in the code (through JSDoc), so the types have changed compared to the previous ones which were maintained manually.
• Dropped support for IE11. You can still transpile the code on your end.

v3.0.1

Minor fixes to the list of published files for v3.
