Thanks, but it's not clear to me whether that help text means Target Standard and Premium only support IE10 or higher for experience authoring (VEC) or for live experience delivery (end users). Could you please clarify? Also, please clarify if this change in browser support occurred on 5/21 as part of the latest Target release, or if it might have been introduced in the latest mbox.js release (version 57) or if if it actually occurred earlier and we just didn't notice that IE8 experiences were no longer rendering.
