Significant improvements have been made to the COBOL compiler and runtime library, focusing on data type interconversions and addressing potential data aliasing issues arising from C-style pointer manipulations. The changes also improve compatibility and correctness on big-endian architectures by handling endianness during compile-time code generation and at runtime.
