No, that’s incorrect. The “Birch” release of the Open edX software was released at the end of February, and many improvements and new features have gone into the Open edX codebase since then. EdX releases a new version of the Open edX software to
edx.org at least once a week, and provides
weekly release notes to document what has changed from week to week. (These release notes are designed for the universities running courses on
edx.org to read, but they are public, and anyone can read them if they want to.)
In addition,
edx.org uses a Drupal-based marketing website in front of the Open edX codebase, and that marketing website is not open source. However, the LMS (courseware) and Studio system used by
edx.org are identical to the ones in the Open edX codebase — because
edx.org deploys directly from the Open edX codebase.
Does that answer your question, Mohannad?
