edX learning platform now all open source

The edX learning platform has now completed its transition to open source and is available under an AGPL licence. The core of the system is the edx-platform which includes both the LMS (Learning Management System) and Studio, a tool for creating courses. Other parts of the system, such as the XBlock component architecture for courseware, machine-learning-based grading such as EASE, the discern tool, deployment tools, interfaces to external grading systems and Python execution utilities, can all be found on the new code.edx.org.
