Lemmy Release v0.9.0

Lemmy Release v0.9.0 Written by @dessalines and @nutomic, 2021-01-25 Changes Since our last release in October of last year, and we’ve had ~450 commits. The biggest changes, as we’ll outline below, are a re-work of Lemmy’s database structure, a v2 of Lemmy’s API, and activitypub compliance fixes. The new re-worked DB is much faster, easier to maintain, and now supports hierarchical rather than flat objects in the new API .
