- ConsoleValue class is now the base value class. - ConsoleValueRef is now used to supply function parameters. Values are disposable. - Script functions return values instead of just strings where possible. - Variables can be disposable strings - Bytecode changed Fix the issues with console method parameters and fields which prevented missions from loading.
