Breaking Changes

Certain ES2015 features are now required

In previous versions, there were automatic fallbacks for certain ES2015 features if they did not exist:

• RegExp.prototype.flags
• WeakMap

Due to the omnipresence of support in both browser and NodeJS, these have been deprecated. There is still an option if you require support for these legacy environments, however; see createCustomEqual and createCustomCircularEqual for more details.

createCustomEqual contract has changed

To allow more flexibility and customizability for a variety of edge cases, createCustomEqual now allows override of specific type value comparisons in addition to the general comparator it did prior. See the documentation for more details.

Enhancements

createCustomCircularEqual added

Like createCustomEqual, it will create a custom equality comparator, with the exception that it will handle circular references. See the documentation for more details.

Cross-realm comparisons are now supported

Prior to 4.x.x., instanceof was used internally for checking of object classes, which only worked when comparing objects from the same Realm. This has changed to instead use an object's StringTag, which is not realm-specific.

TypeScript typings improved

For better typing in edge-case scenarios like custom comparators with meta values, typings have been refactored for accuracy and better narrow flow-through.
