At Heroku, we want to give our users access to the latest and greatest software stacks to base their apps on. That’s why we continuously update buildpacks to support new language and framework versions and let users experiment further using third-party buildpacks.
Sitting underneath slugs and buildpacks are stacks. Stacks are the operating system and system libraries required to make apps run. Today we’re releasing into public beta a new version of the Celedon Cedar stack:
cedar-14 is built on the latest LTS version of Ubuntu Linux and has recent versions of libraries and system dependencies that will receive maintenance and security updates for a long time to come.
cedar-14 the default stack, Heroku is looking for feedback from our users. To help weed out bugs and problems, please try out the stack with existing apps and new source code.
