I'm with the majority here. If you're there long term it'll come out one way or another sooner or later. You form friendships with collegues and they meet some of your old friends at some party or something or on a fishing trip maybe and someone says something and there goes the whole kit and kaboodle. Better off not having to remind your old friends never to mention it and better for you not to carry the stress of not telling around with you all the time either. It'll only effect your performance in the end.
Besides, who wouldn't love you warts and all plth?
