The main reason I was asking this is because I fully expect the
upgrade to PHP7 (if a newer version of PHP5 doesn't do it first) to
break parts of Capacity. I'm not sure to what degree this breakage
The current server that hosts all of the Capacity sites runs Ubuntu
14.04, and I fully expect to be upgrading that container sometime in
the next 6 months or so to the current LTS release, 16.04.
The code within individual Capacity pages shouldn't be affected much,
it'll be the Capacity core that breaks.

Okay. That's good to hear.
