API Changes

This section documents version-specific API changes for TypeScript v5.7+, prioritizing recent major/minor releases.

• BREAKING: ArrayBuffer no longer supertype of TypedArray types — v5.9 changed ArrayBuffer relationships; methods expecting ArrayBuffer now reject Uint8Array, Buffer, etc. Fix by accessing .buffer property or using specific Uint8Array<ArrayBuffer> types source
