NOTICE

Soon master branch, website/docs and godoc will be pointing to v2 branch, if you want to continue using v1, use a package manager (https://github.com/Masterminds/glide, it's nice!) to get a stable v1 release or latest commit or you can use https://gopkg.in like go get gopkg.in/labstack/echo.v1. It is advisable to migrate to v2.
