Linux Mint 18.2 Ubuntu-based OS is Named 'Sonya' (betanews.com)
Brian Fagioli, writing for BetaNews: The uncertainty about Ubuntu has not deterred the Linux Mint team, however, as they are moving ahead with plans for version 18.2.

First, the code name for the OS will be 'Sonya,' and second, the distro will use LightDM as default display manager.
Well, if it's running plugins automatically, then the bar to exploiting it has dropped considerably from "until you install a malicious theme". Now the exploit could be as simple as "Malicious plugin", or as complex as "Someone, somehow, because that NEVER happens, finds a bug in Adobe Reader, that they can exploit."
That's my major concern.
You are not alone. This is not normal. None of this is normal.
