Nav-view/view vs pane/nav-page and hide-back-button

I’m hoping someone can point me in the right direction. I have the latest version of ionic v0.9.23, which has the seed project using ui-router with nav-view and view tags to render all the appropriate templates. I was googling around on how to remove the back button that appears from the nav-bar and came across this forum link, which then led me to find this link. In both there is talk of a pane and nav-page. Is this just referencing an older version of ionic? If so, is there a way currently using the ui-router version to still use “hide-back-button” because I cannot seem to get it to work?

I’m hoping someone can clarify this for me.
