I upgraded to version 2.7.1 about three weeks ago and all has been running fine on my site, however this morning as I logged into my blog's Admin screen I saw the message at the top and bottom of the screen indicating that version 2.7.1 has been released and that I can upgrade to it. I visit my site every day so this is not an oversight. Another strange thing, I do not know if it is related, is that I received a comment from someone in Russia requesting me to email him back so he that can link me - I deleted his post. Is it possible my site has been hacked? Has anyone else encountered this issue where you are already on a version, for a few weeks, and then suddenly the same version is available for upgrade?
