Hi

I tried the new version of the plugin and added the git-hub pref but it did not trigger update to 4.2.1. as expected.

On a virgin ePub3 created by Sigil, epubcheck 4.20. reported this (screenshot)

Edit

After using the following pref text, it duly updated to 4.2.1. and reported the same error and warning (screenshot).

{
  "update_check": true,
  "clipboard_copy": false,
  "java-lang": "fr",
  "github": true,
  "last_time_checked": "2019-05-21 10:07:34.967911"
}
