+# Lemmy v0.9.0 Release (2021-01-25)
+
+## Changes
+
+Since our last release in October of last year, and we've had [~450](https://github.com/LemmyNet/lemmy/compare/v0.8.0...main) 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](https://github.com/LemmyNet/lemmy/issues/1275).
+
+We've also seen the first release of [Lemmur](https://github.com/krawieck/lemmur/releases/tag/v0.1.1), an android / iOS (soon) / windows / linux client, as well as [Lemmer](https://github.com/uuttff8/Lemmy-iOS), a native iOS client. Much thanks to @krawieck, @shilangyu, and @uuttff8 for making these great clients. If you can, please contribute to their [patreon](https://www.patreon.com/lemmur) to help fund lemmur development.

+## LemmyNet projects
+
+### Lemmy Server
+
+- [Moved views from SQL to Diesel](https://github.com/LemmyNet/lemmy/issues/1275). This was a spinal replacement for much of lemmy.
+  - Removed all the old fast_tables and triggers, and created new aggregates tables.
+- Added a `v2` of the API to support the hierarchical objects created from the above changes.
+- Moved continuous integration to [drone](https://cloud.drone.io/LemmyNet/lemmy/), now includes formatting, clippy, and cargo build checks, unit testing, and federation testing. [Drone also deploys both amd64 and arm64 images to dockerhub.](https://hub.docker.com/r/dessalines/lemmy)
+- Split out documentation into git submodule.
+- Shortened slur filter to avoid false positives.
+- Added query performance testing and comparisons. Added indexes to make sure every query is `< 30 ms`.
+- Added compilation time testing.
+
+
+### Lemmy javascript / typescript client
+
+- Updated the [lemmy-js-client](https://github.com/LemmyNet/lemmy-js-client) to use the new `v2` API. Our API docs now reference this project's files, to show what the http / websocket forms and responses should look like.
+- Drone now handles publishing its [npm packages.](https://www.npmjs.com/package/lemmy-js-client)
+
+### Lemmy-UI
+
+- Updated it to use the `v2` API via `lemmy-js-client`, required changing nearly every component.
+- Added a live comment count.
+- Added drone deploying, and builds for ARM.
+- Fixed community link wrapping.
+- Various other bug fixes.
+
+
+### Lemmy Docs
+
+- We moved documentation into a separate git repository, and support translation for the docs now!
+- Moved our code of conduct into the documentation.
+
+### Federation
+
+This release includes some bug fixes for federation, and some changes to get us closer to compliance with the ActivityPub standard.
+
+- fixed: [Community bans not federating](https://github.com/LemmyNet/lemmy/issues/1287)
+- fixed: [Local posts sometimes got marked as remote](https://github.com/LemmyNet/lemmy/issues/1302)
+- fixed: [Creator of post/comment is not notified about new child comments](https://github.com/LemmyNet/lemmy/issues/1325)
+- fixed: [Community deletion not federated](https://github.com/LemmyNet/lemmy/issues/1256)
+
+None of these are breaking changes, so federation between 0.9.0 and 0.8.11 will work without problems.
+
+
+## Upgrading
+
+If you'd like to make a DB backup before upgrading, follow [this guide](https://lemmy.ml/docs/en/administration_backup_and_restore.html).
+
+- [Upgrade with manual Docker installation](https://lemmy.ml/docs/en/administration_install_docker.html#updating)
+- [Upgrade with Ansible installation](https://lemmy.ml/docs/en/administration_install_ansible.html)
