 I suggest that we provide an option to only check the latest release
 instead of tags. This could be useful for many ports like git-lfs, irssi,
 weechat, syncthing-0.14 that have rc or snapshot tags. The following line
 works but setting it in the PG is better in case the url changes.

 {{{
 livecheck.url   ${github.homepage}/releases/latest
 }}}
