Let's hear from Jeff on copyright and open licensing.
When assigning a Creative Commons license to your work, be sure to use the most up-to-date version of the license. The most up-to-date versions of Creative Commons licenses are the 4.0 International Licenses. Versions 3.0 and up will still work flexibly for you and for other instructors who would like to use your works.
Works with versions 2.0 and below will have outdated attribution standards which could be enforced strictly by rightsholders; be sure to pay attention to the version number of the open license when remixing and revising other works and follow the directions for attributing these correctly.
