Lemmy 0.18.1 Release

Lemmy 0.18.1 dropped yesterday and seems to bring a lot of performance improvements. I have already updated the sandbox instance to it and am noticing that things are indeed loading quicker.

I'm planning to upgrade this instance sometime tomorrow evening (8/9 around 6-7pm EST). Based on the update in sandbox, I expect a couple minutes of downtime while the database migrations run.
