<If you do want to move the curve for some reason without updating the revolved object, you can disable history on the revolve by selecting it and going to Edit/History.

It's that was not explicit :) History installed by default

Yeah, at first I tried enabling history on everything by default. But several things such as copy and mirror could have pretty surprising results. So I couldn't really turn it on for everything by default.

But I thought that I would turn it on by default for these commands: Extrude, Revolve, Rail Revolve, Sweep, Blend, Offset curve, Planar curve, and Loft.

These seem to be ones where a lot of people are expecting history to work on, so I wanted to make it work automatically here, instead of having to manually turn it on for these.

It can still be a bit surprising if you're not thinking about it when you move the original curves around, though.

It seems that when i click history with no objects selected, it pops up the extrude tool's dialog (select curves...to extrude), i'm assuming this is an error. Functionally there is no problem.

Yup, it is a typo in the command UI.

Thanks for reporting it, it's fixed for the next beta release.
