I am currently running ENBoost with no graphic enhancements. Everything seems to work okay, but I am getting a message on loading a savegame that there is a new update to the ENBseries. The latest version is v0.272. Is there a reason to update if you are only running ENBoost with no ENB related graphical modifications?

Also, do I need the "helper" dll to run weather mods like Climates of Tamriel, or is that only needed for ENB weather mods?
