Show HN: New release of my startup, Interstate (http://interstateapp.com)

My startup, Interstate (http://interstateapp.com) has just launched a new version (v4). The new version has brought a lot of new features and tons of UI/code/existing feature improvements (a full rundown of all the major changes can be found on our blog: http://blog.interstateapp.com/post/4416998498/major-roadworks-on-interstate).

For those who have never heard of us before, Interstate provides developers and businesses alike a way to plan and share their development progress using roadmaps.

If anyone has any feedback or would just like an invite then please do post! :)
