Change effective on 22 April 2015
Previously, if you inputted
ctrl+c during a SSH git-push to Heroku, Heroku would attempt to cancel the build and not create a new release. As of now, inputting
ctrl+c during a build created with SSH git-push will simply detach from the build output stream. The build will continue and a release is created if the build is successful. This brings SSH Git behavior in line with HTTP Git.
See the Dev Center Git documentation for details.
