Hi Andrey, Given that 8.2.1 is finally starting to come together, now is probably a good time to start reflecting on what will come in 8.4. I think it would be great if we could finally get Hadrian into the tree for the 8.4 release. It would be even better if we could flip over to Hadrian as the primary build system. However, if we are to do this then I think we should leave plenty of time to iron out the inevitable bugs that will arise. Have you given much thought to the schedule post-8.2? Do you think a complete switch-over will be feasible? Cheers, - Ben
