Version 7.4.2: Enhanced support for parameterless value type constructors (mentioned in GitHub Issue #444); fixed COM-related memory leak on .NET Framework (GitHub Issue #510); enabled multidimensional array manipulation via VBScript indexing syntax (GitHub Issue #511); improved stability on Apple Silicon devices. Tested with V8 11.4.183.17.
