Will my current progress in the project be gone, if I update the published changes/work of my co-developer? (Unity Collaborate)

Good day madam/sir! We are using Unity Collaborate for our project. I would like to know, if my co-team/developer published changes in the project while I am working on my changes too which are not yet publish. Will my current progress/changes be gone if I updated the project? Much appreciation for noticing and answering my question.

Only if they are working on the same things you are scenes/scripts.
