I've updated the sound cloud plugin. But not pushed it to npm. Will do it when I get to work shortly.
You can clone it directly from github at the minute though.
In my NodeBB admin area the latest version of nodebb-plugin-imgur is 0.1.4. However, looking at the GitHub repo, version 1.0.0 was released 5 days ago. It doesn't give me the option to update the plugin in the admin area. How else can I update to version 1.0.0?
npm update nodebb-plugin-imgur will install the latest version from npm. Do remember that when you do this with any plugin, you won't get the compatibility warnings if the plugin is not compatible with your NodeBB version.
The ACP page should show the latest version now.
