 # hash-it CHANGELOG
 
+## 6.0.0
+
+**Breaking changes**
+
+- Equality utilities (`is` / `is.any` / `is.all` / `is.not`) are no longer provided
+- `Error` type hashes now include the message (previously only included stack)
+- Non-enumerable type hashes (`Generator`, `Promise`, `WeakMap`, `WeakSet`) now hash uniquely based on reference
+- `WeakMap` is now required at runtime (used as cache for circular references)
+
+**Enhancements**
+
+- Better support for system-specific loading (ESM vs CJS vs UMD)
+- Added support for primitive wrappers (e.g. `new Number('123')`)
+- Added support for more object classes
+  - `AsyncFunction`
+  - `AsyncGeneratorFunction`
+  - `BigInt64Array`
+  - `BigUint64Array`
+  - `GeneratorFunction`
+  - `SharedArrayBuffer`
+  - `WeakRef` (same limitations as those for `WeakMap` / `WeakSet`)
+
 ## 5.0.2
 
 - Reduce code size by 29.29% (19.42% gzipped size)
