• Added disable_forks flag. When set to true the resource will no longer produce new versions (or trigger) if the pull request is from a fork. Thanks to @tlwr!
• Docker images are now built from the official Alpine 3.8, with the latest versions of git and openssh installed. The new Dockerfile also has fewer layers (thanks @rickardl), and reduced size (mainly because binaries are now being stripped using ldflags).
• Readme now has a link to the official documentation for setting up webhooks on a resource. Thanks @osis!
