Around end of this month there will be an MR of PB 2017 R2. July 31, 2018 is the tentative date for PB 2017 R3, which will of course include additional fixes but also offers some new features/enhancements, such as OAuth support and additional JSON-related features, enhancements to Git and SVN integration, enhancements to the native PDF, SQL Server 2017 support, etc. In my opinion, PB 2017 R3 is a must-have upgrade for most customers.
I agree that Appeon is doing a great job. But I'm only saying that there should be some emphasis on quite a few bugs. Like your comparison with 'road works', you would first want to have it asphalted before having fancy stuff added to it, unless you can afford to wait. Maybe you are lucky and don't use stuff like rte and your clients don't care too much about transparencies, different spacing and having memory leaks. Ours do, so that's why we have to wait.
