How to get notified when a plugin update is available?

Hello,

I'm developing a R# extension to share code style settings across the team. So far so good, developers are able to install it. But when I publish an update there is no notification and I have to send a message to everyone to ask them to update the extension.

Am I missing something? Is there a way to get a "flag" or something like that to indicate a new update is available?

Thanks and regards
