Publish Date of Lessons and Courses
We have a team of programmers that review lessons and courses on a daily basis. They keep the code up to date with the latest versions, and make sure that is runs as expected. When the code and video are out of sync in a way that causes excessive confusion, we mark the lessons as such and slate them to re-record.
We aren't adding dates to courses and lessons. Instead we are gonna make every effort possible to keep the content relevant.
