Q: I'm writing an application using the Open Transport native APIs. My original intention was to ship only a 68K version of the application, but I've heard that this will not be compatible with future versions of OT. Is this true?
A: Yes. We strongly recommend that you ship all OT native applications as fat applications. This will give your applications the maximum speed and compatibility.
Under System 7, OT provides OT native APIs for both 68K and PPC clients. This allows 68K OT clients to operate under emulation on PPC Macintoshes. This will not be supported under Copland, because Copland will not support the Apple Shared Library Manager, the dynamic linking technology used by 68K OT clients. Table 1 summarizes this information.
