WB2.7 is a stable version, and WB as a project is not stagnated. There are addons developed all the time. WB is alive and kicking. There is nothing to keep you from using WB2.7. Sure we are all looking forward to a new release version, but many new features are already available as addons right now.
No one knows when WB2.8 will be out, so please don't ask for it. There is no company behind WB, and there is no team that can put a fixed amount of time and effort in the project. When people have time, they contribute. And when all set aims for WB2.8 are reached, it will be released. So please don't blame anyone that 2.8 is not there yet. Instead, support the project if you can in any way. If you cannot support it, just wait for 2.8 and use 2.7 until then. It's a fine CMS, and 2.8 is not some holy grail. It is just a new version, and it will be there one day.
