a screenshot from Ghost's website with the title: Developer changes and below, the following text: "On top of all the user-facing changes, we also have some exciting updates and changes for developers who build-on and work-with Ghost.
Ghost 6.0 represents the beginning of a major improvement to how Ghost is deployed. Up until now, Ghost has been installed with Ghost-CLI as a single app that runs on a VPS with one MySQL database, but our new social web and analytics features have been built as independent services that run alongside Ghost. So, we're moving toward Docker Compose as the officially supported way to install, run and update Ghost. This is now available as a developer preview, and will become the default from Ghost 7.0 onward."
