Sorry, scratch that - this is a really old version. The real question is therefore why the wiki page I found on google points to such an old version?
In fact, https://github.com/POSSA/Caller-ID-Superfecta/wiki also points to old versions.
incidentally, I went the root of searching out official install instructions because superfecta didn't appear on the list of available modules in Module Admin after an online check.
I tried the trick of then doing an online check (which then found the latest version) and clicking on install, but although it said it was going to install the latest version it actually tried to install the old version.
Finally sorted it by selecting every repository, apparently Superfecta is in 'extended'. Perhaps the wiki pages should be updated to point to using module admin and selecting 'extended' before doing an online check?
