It will likely show up on htc.com , that's what happened with the last security update. Rogers.com will have a link too, a little harder to find it. As to whether or not it wipes your phone, it won't be an option. It will or it won't. Be aware with the last official upgrade they upgraded some phones to make it much trickier to root should you choose to in the future. It was an action that convinced me to root my phone, and i previously had no interest in that, so rogers/htc fail there.
