I am about to go home sick, so I hope this is coherent. We will be make a release of the Andrew software on the X.V11R4 tape. We sent a preliminary (beta) version that software to MIT for inclusion on the X.V11R4 beta tape, and to selected beta sites of our own. At the moment, we are working with those sites to debug the installation procedures for the whole system, which is currently about 35 megabytes of source. Once we have our beta sites going (we hope to send them some patches soon -- they are being verified as I write this), I will send out general information to the info-andrew mailing list describing what is going on and how interested parties can try a beta version. As to your specific questions: - what classes/methods/protocols exist now that will change or disappear The basic view and data objects remain the same, as is the basic view-data model. We haven't generated a diff of the changes on a method-by-method basis, and I don't think we could say anything more meaningful. However, the class system has been reworked to make it much easier to port to new machines. - will the graphics model change to a postscript model No - will hard copy output still be troff or will it be postscript or TeX Text is still troff; some insets generate postscript directly. - will there be more support in the base classes for color No, still Fore/back RGB - will the class language support class methods that can be overridden No - will there be a garbage collector No - will the WantUpdate - Update protocol change (since many of the basic classes don't follow it and draw in the window during Hits) To the best of my knowledge, the definition of the drawing protocol allows drawing during Update *and* Hit. Finally, will the ITC make this new version of the ATK available prior to the XR4 release? Yes. More information as it is available. Mark Sherman Manager, Applications Group

Does the XR3 release of andrew (I think that was andrew version 2) work with the XR4 Xlib and server on an IBM RT? I looked into upgrading to andrew version 3, but decided to avoid that as long as possible.
