+### Breaking Changes
+* Replace deprecated `convertStringToHex` and `convertHexToString` functions with modern equivalents `stringToHex` and `hexToString`. The new functions are imported from `@xrplf/isomorphic/utils`. While the old function names remain re-exported from the xrpl package for backward compatibility, they are deprecated and will be removed in a future major version. Direct usage throughout the codebase has been updated to use the new function names.
