We took a little extra time with this one, but it was worth it. A primary theme of 0.4 was how the ESB can be used in the context of governance, at design-time and runtime. We're really happy with the progress we've made there and we're just getting warmed up. In total, there were 105 JIRAs resolved in 0.4, so there's plenty in there beyond governance as well. The juicy details can be found in the SwitchYard 0.4 Release Overview, which contains a list of all the new features with pointers to examples and documentation on each.
We have a sizeable backlog of videos we've been planning on everything from getting stuff installed, to feature profiles, to exploration of the more obscure aspects of the project. So stay tuned and let us know what you think!
