Lemmy v0.9.0 Release (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.
We’ve also seen the first release of Lemmur, an android / iOS (soon) / windows / linux client, as well as Lemmer, a native iOS client. Much thanks to @krawieck, @shilangyu, and @uuttff8 for making these great clients. If you can, please contribute to their patreon to help fund lemmur development.
LemmyNet projects
Lemmy Server
- Moved views from SQL to Diesel. This was a spinal replacement for much of lemmy.
- Removed all the old fast_tables and triggers, and created new aggregates tables.
 
 - Added a 
v2of the API to support the hierarchical objects created from the above changes. - Moved continuous integration to drone, now includes formatting, clippy, and cargo build checks, unit testing, and federation testing. Drone also deploys both amd64 and arm64 images to dockerhub.
 - 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.
 
Federation
This release includes some bug fixes for federation, and some changes to get us closer to compliance with the ActivityPub standard.
- Community bans now federating.
 - Local posts sometimes got marked as remote.
 - Creator of post/comment was not notified about new child comments.
 - Community deletion now federated.
 
None of these are breaking changes, so federation between 0.9.0 and 0.8.11 will work without problems.
Lemmy javascript / typescript client
- Updated the lemmy-js-client to use the new 
v2API. 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.
 
Lemmy-UI
- Updated it to use the 
v2API vialemmy-js-client, required changing nearly every component. - Added a live comment count.
 - Added drone deploying, and builds for ARM.
 - Fixed community link wrapping.
 - Community Titles are now used instead of names.
 - 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.
