Problem:Question: I am developing some software where users are assigned tasks. They will see a date and time for when they were assigned to the task, but if they were later removed from the task, there will be a date and time for that also. 01/02/14 - Assigned 03/02/14 - Unassigned I'm pretty sure unassigned isn't correct. I suppose the task itself could be in a state of being unassigned, but the user wasn't "unassigned" from it. Notes: I don't want to use the word "removed", as I don't think it conveys the correct meaning and also sounds too harsh. I would like to avoid using a word your average person would never have heard of, as this isn't very user-friendly from a software point of view.
Answer: "revoked", "withdrawn", "retracted", or simply "reassigned".

yes
