All projects allow this including unix UI projects you mentioned. In most cases the update of the GUI for a next R version consists of re-compiling the GUI, that's all. Again, this is always necessary, independent of the API, for various reasons (some of them platform-dependent such as that with new R version the location of the R dynamic library may have changed). The API changes usually add new functionality and hence new possibilities. As Philippe was saying, the delays are then not because of API changes, but because the GUI authors want to take advantage of that new functionality. (In the last 6 releases of R I remember only two restructuring changes in the API, both taking less than 5 lines of code to adapt to - modulo graphics devices, of course). I didn't check all the GUIs, but for JGR I can say that you can get it immediately at the time of R release if you compile it from sources. From my point of view I can say that building and testing of installers and binaries takes far more time than fixing the code for API changes. If you are willing to build and test binaries during the R beta phase, you're encouraged to do so - that would make the GUI available right on time for the R release.
