Plugin breaking soon?

Hello! I use this plugin on the website for a meetup that I help run. We really like it a lot, thanks! However, I’ve been getting emails from Meetup.com that they’re discontinuing their old API. Will that break this plugin? Are there any plans to update this plugin, or is there a similar alternative? I haven’t been able to find anything else that just displays upcoming meetups in the sidebar.

Thanks!

Mike
