grishka, 
#Smithereen 0.7 is out, finally making it practical to run a server with open signups.
This release brings too many changes to list here, both internal and external.
- All-new moderation tools: role-based permissions, revamped reports, new ways of limiting user accounts, and so much more!
- All-new media storage: Smithereen now keeps track of references to files, simplifying the code, and adds support for S3 object storage.
- Tens of minor bug fixes and UX improvements.
