This is embarrassing, but about an hour ago I was alerted to an issue where edited, local-only posts in #Hometown were being federated. Please update your Hometown servers ASAP.

More info at the security patch link:

https://github.com/hometown-fork/hometown/releases/tag/v4.0.2%2Bhometown-1.1.1

Most servers ignore or throw away the leaked data because it's an edit to something that it never received (the original post).

Still, unacceptable, and I'm sorry for this trouble, esp on a Friday night. I will do my best to contact admins individually.
