This Week in Flynn

After several months of development, we’ve added overlay networking to Flynn. Every container running in Flynn is now accessible through its own unique, cluster-routable IP address. This eliminates complicated networking configurations and opens the door to dramatic improvements in service discovery and cloud integration.

Also added this week, the Flynn dashboard now automatically detects and displays buildpack compatibility for apps deployed from GitHub. The interface will provide links to relevant documentation before you deploy your app, or warn you about missing buildpacks.
