 v5.4.1
 ---
+* Fixed `Utils.nodeRequire` causing `ReferenceError: require is not defined` in browser build by making it lazy-evaluated
 * Fixed missing space between keywords (`return`, `throw`, `typeof`) and Unicode surrogate pair identifiers in compact mode. Fixes https://github.com/javascript-obfuscator/javascript-obfuscator/issues/1112
 * Fixed `domainLock` being case-sensitive — domain values are now normalized to lowercase. Fixes https://github.com/javascript-obfuscator/javascript-obfuscator/issues/1182
 * Removed `source-map-support` runtime dependency. Use `node --enable-source-maps` instead. Fixes https://github.com/javascript-obfuscator/javascript-obfuscator/issues/1149
