Many claimed "upd" PDFs are simply the original edition renamed. Check the copyright page: the updated edition has a line saying "First published 2024, Revised printing November 2024." the theoretical minimum general relativity pdf upd
Read Susskind's "Historical Aside" (new in upd) – Einstein had no rigorous derivation. The equations are the simplest possible curvature–matter relationship consistent with conservation of energy. That humility is valuable.

Before the material was published as a physical book, André Cabannes compiled detailed PDF lecture notes based directly on Susskind’s Stanford video lectures. These notes remain widely available across academic repositories and personal physics blogs, serving as an excellent free, legal open-source companion to the textbook.
