The notifications show the markup e.g. "b" and "/b" instead of enacting them. I do not know whether anybody else or everybody else gets them; I am on a prior stable version when elive installed e17 (not e16) BTW I am omitting the < and > just to make things clearer
The notification is in the top right corner of Elive screenshot on imagebin.ca. Instead of seeing bold text like this you see the markup text "b" "/b". Initially I thought the application Guake in this example was responsible, but perhaps the message handler does not interpret correctly. Not a critical item, so maybe just something that can be improved with each beta.
