With PHPFusion 5 due out, I'm happy to announce that there are to be no further major structure changes AFTER this release. This does not mean the project is to cease development, that simply is not the case. I intend to continue improving PHPFusion wherever possible, but what will change is the constant need to strip out modded code whenever you upgrade to each new release. So PHPFusion is just going to be bigger and better, it is also going to be easier to keep up to date!
