Hi, We are considering switching from vB 5 (going back to 4 is obviously not an option, neither is keeping the mess they made when releasing 5), and I've been going through the usual pre-sales questions to see if our needs are covered by XF. One answer I could not yet find; my apologies if I overlooked the answer: will it be necessary to touch the custom style (CSS and native code, if there are style variables like vB has, possibly graphic assets) each time there is a major update of XF? For vBulletin, it became necessary if updates led to style variables being deprecated, and so forth. Of course, we'd like to be able to update and keep the necessary maintenance and adjustments in terms of the style to an absolute minimum. We're usually outsourcing the creation of the style, so becoming dependent on someone external to touch the style again after a new version of XF has been released is something we would like to avoid if possible. Thanks in advance!
