We have updated our Lemmy instance to v0.18.3.

Highlights:

• Improve api response times by doing send_activity asynchronously
• Add infinite scroll user option
• Add controversial ranking

This version brings major optimizations to the database queries, which significantly reduces CPU usage. There is also a change to the way federation activities are stored, which reduces database size by around 80%. Special thanks to @phiresky for their work on DB optimizations.
