Use it for what? If you want to put something verbatim, just source it (unless they specifically say otherwise, or license it otherwise). If you just want to use it for dates, or general information and such, just put that you took it from the Transformice update log in the "Edit Summary" if you want to be safe.

(although honestly, as long as your not screwing someone out of money or using their work in a way they didn't intend, people rarely care)
