Maintainers

Blender's code is organized in modules; libraries or directories with files sharing a certain functionality. For each module the module owners are responsible for maintenance and bug fixes. They also define - together with their team - roadmaps or todos for the module, aligned with the overall release cycles and roadmaps.
