I noticed that the creation kit updated today when I logged into steam, I tried to look for a change log both on steam news, creationkit.com and here and I can't seem to find anything about what this update did.

Can someone tell me what changed or link me to the current change log?

There's an update? What is your version number?

I leave steam in offline mode. I dont like the auto update happening when my back's turned. Call me old fashioned, but I like to be the one in charge when things get installed on my pc

If I remember correctly, Dawnguard's Papyrus source files were added to the Creation Kit but the program itself was unchanged.

Was probably the Dawnguard PSCs. Check for a new Dawnguard subfolder in Data\Scripts\Source, or had you already gotten that update?
