theodinproject/curriculum is a public curriculum repository for learning web development. There is no official release history, so the changes in any specific version cannot be confirmed. What can be done instead is to look at the structure and scope of the published curriculum.
This repository holds learning materials rather than service code. The README explains that you can practice what you learn through the lessons and projects of each course, and place finished projects in a portfolio. It is a project-based, hands-on full-stack web development curriculum that teaches programming through step-by-step lectures and implementation exercises. The actual frontend and backend code of The Odin Project app live in the main repository, and this repository contains only the lesson files used on the website. The primary language is JavaScript, it has 13170 GitHub stars, and it was created on June 11, 2013.
That said, the terms of use and the current state are hard to confirm. The license field is still NOASSERTION, so the actual license name cannot be known. In the evaluation scores, the novelty, technology and quality items are empty, and only momentum came out at 3.0. With no release history, there is no way to know what has changed recently, and the star count only reflects a known scale rather than current activity. It is clear that this is a published learning course separated from the app code, but since the update cadence and the terms of use are unknown, it is difficult to decide what to expect.
