Wasn't there to the best of my recollection, hence my original question. I think I got the 5.1 from the app store. Possible I missed it, but I was specifically looking for it. Evernote (the app) told me to go to the web to get a new version (when I ventured into some area low on the left side bar). It didn't suggest to check for updates via a menu option. I nuked the evernote.app directory and initiated a new install. Evernote installer said something about finding an old app store version and needing to copy all my notes over. it's mid-copy right now. Looks like I'll be back up as soon as this copy finishes, incredibly slow copy though.
