Following an upgrade to PHP7.0 (7.0.0-4 on Debian sid), I now get the following message each time cliupdate.php is run from a cron job.

"Methods with the same name as their class will not be constructors in a future version of PHP; floIcon has a deprecated constructor
an error occured"

The update appears to still work so I think this is an information rather than critical warning, but might need a tweak for a future version of selfoss as more people move to PHP7.
