Lemmy v0.10.0 Release (2021-04-05)

Changes

Since our last release in February, we've had ~150 commits to Lemmy. The biggest changes, as we'll outline below, are a split of Lemmy's user tables into federated and local tables, necessitating a v3 of Lemmy's API, federated moderation, i18n support in join.lemmy.ml, and lots of back-end cleanup.

Lemmy Server

General

• Rewrote config implementation, finally allowing us to use newer Rust versions.
• Removed categories.
• Various refactors.

API

• A full list of the API changes can be seen on this diff of lemmy-js-client: 0.9.9 -> 0.10.0 .
• Login invalidation on password change, thanks to @Mart-Bogdan

Federation

• It is now possible to add users from other instances as community mods.
• Federating Matrix ID.
• Many changes for better compatibility with ActivityPub standard.

Database

• Split the user_ into person and local_user tables.
• Strictly typed commonly used ID columns, to prevent DB errors using i32 as ids.
• Strictly typed URL fields, thanks to ajyoon.
• Created default DB forms, now used in all the unit tests.

Lemmy UI

• Now using utf-8 emojis.
• Support for all the above changes to Lemmy.
• Typescript-safe i18n strings, thanks to @shilangyu.
• Added expandable post text (click on open book icon).
• Prettier cross-posting, which does smart quoting.
• Bugfixes for restoring scroll position on post page, custom site favicons, and autocomplete for login fields.

Lemmy Docs

• Gazconroy built an Async API spec for Lemmy, that now serves as our main API docs.

join.lemmy.ml

• Rewrote in inferno isomorphic, added i18n support via weblate.
• Added a section on the support page thanking contributors.
• Changed some page urls / titles

Upgrade notes

Important: there are multiple breaking changes:

• Configuration via environment variables is not supported anymore, you must have all your config in the lemmy.hjson file ( except for LEMMY_CONFIG_LOCATION ).
• The config format for allowed_instances and blocked_instances has changed, and you need to adjust your config file manually:
  • before: allowed_instances: ds9.lemmy.ml,enterprise.lemmy.ml
  • now: allowed_instances: ["ds9.lemmy.ml", "enterprise.lemmy.ml"] , and only one of the allowed_instances or blocked_instances blocks can be set.
• The API has been upgraded from v2 to v3, so all clients need to be updated: lemmy-js-client: 0.9.9 -> 0.10.0 .

If you'd like to make a DB backup before upgrading, follow this guide.

To upgrade your instance to v0.10.0, simply follow the instructions in the documentation:

• Upgrade with manual Docker installation
• Upgrade with Ansible installation

Compilation time

	v0.9.0 (Rust 1.47)	v0.10.0 (Rust 1.47)	v0.10.0 (Rust 1.51)
Clean	140s	146s	119s
Incremental	28s	22s	19s

Despite ongoing efforts to speed up compilation, it has actually gotten slower when comparing with the same Rust version. Only thanks to improvements in newer Rust versions has our build process gotten faster. This could be simply because we added more code, while Lemmy v0.9.0 had 22.4k lines of Rust, v0.10.0 has 23.8k (an increase of 6%).

v0.9.0 build graph:

v0.10.0 build graph:

We extracted the crates lemmy_api_crud and lemmy_apub_receive from lemmy_api and lemmy_apub, respectively, and renamed lemmy_structs to lemmy_api_common. In the second graph you can see how parts of the api and apub crates are now built nicely in parallel, speeding up builds on multi-core systems.

On the other hand, some crates have gotten much slower to compile, in particular lemmy_db_queries (6.5s slower), lemmy_apub (6.5s slower if we include lemmy_apub_receive). And lemmy_db_views is quite slow, just as before.

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 v2 of 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 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.

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.

Upgrading

If you'd like to make a DB backup before upgrading, follow this guide.

• Upgrade with manual Docker installation
• Upgrade with Ansible installation

Lemmy v0.8.0 Release (2020-10-16)

Changes

We've been working at warp speed since our v0.7.0 release in June, adding over 870 commits since then. 😓

Here are some of the bigger changes:

LemmyNet projects

• Created LemmyNet, where all lemmy-related projects live.
• Split out the frontend into a separete repository, lemmy-ui
• Created a lemmy-js-client, for any js / typescript developers.
• Split out i18n lemmy-translations, that any app or site developers can import and use. Lemmy currently supports ~30 languages!

Lemmy Server

Federation

• The first federation public beta release, woohoo 🎆
• All Lemmy functionality now works over ActivityPub (except turning remote users into mods/admins)
• Instance allowlist and blocklist
• Documentation for admins and devs on how federation works
• Upgraded to newest versions of @asonix activitypub libraries
• Full local federation setup for manual testing
• Automated testing for nearly every federation action
• Many additional security checks
• Lots and lots of refactoring
• Asynchronous sending of outgoing activities

User Interface

• Separated the UI from the server code, in lemmy-ui.
• The UI can now read with javascript disabled!
• It's now a fully isomorphic application using inferno-isomorphic. This means that page loads are now much faster, as the server does the work.
• The UI now also supports open-graph and twitter cards! Linking to lemmy posts (from whatever platform you use) looks pretty now:
• Improved the search page ( more features incoming ).
• The default view is now Local, instead of All, since all would show all federated posts.
• User settings are now shared across browsers ( a page refresh will pick up changes ).
• A much leaner mobile view.

Backend

• Re-organized the rust codebase into separate workspaces for backend and frontend.
• Removed materialized views, making the database a lot faster.
• New post sorts Active (previously called hot), and Hot. Active shows posts with recent comments, hot shows highly ranked posts.
• New sort for Local ( meaning from local communities).
• Customizeable site, user, and community icons and banners.
• Added user preferred names / display names, bios, and cakedays.
• Visual / Audio captchas through the lemmy API.
• Lots of API field verifications.
• Upgraded to pictrs-v2 ( thanks to @asonix )
• Wayyy too many bugfixes to count.

Contributors

We'd also like to thank both the NLnet foundation for their support in allowing us to work full-time on Lemmy ( as well as their support for other important open-source projects ), those who sponsor us, and those who help translate Lemmy. Every little bit does help. We remain committed to never allowing advertisements, monetizing, or venture-capital in Lemmy; software should be communal, and should benefit humanity, not a small group of company owners.

Upgrading

• with manual Docker installation
• with Ansible installation

Testing Federation

Federation is finally ready in Lemmy, pending possible bugs or other issues. So for now we suggest to enable federation only on test servers, or try it on our own test servers ( enterprise, ds9, voyager ).

If everything goes well, after a few weeks we will enable federation on lemmy.ml, at first with a limited number of trusted instances. We will also likely change the domain to https://lemmy.ml . Keep in mind that changing domains after turning on federation will break things.

To enable on your instance, edit your lemmy.hjson federation section to enabled: true, and restart.

Connecting to another server

The server https://ds9.lemmy.ml has open federation, so after either adding it to the allowed_instances list in your config.hjson, or if you have open federation, you don't need to add it explicitly.

To federate / connect with a server, type in !community_name@server.tld, in your server's search box like so.

To connect with the main community on ds9, the search is !main@ds9.lemmy.ml.

You can then click the community, and you will see a local version of the community, which you can subscribe to. New posts and comments from !main@ds9.lemmy.ml will now show up on your front page, or /c/All

Lemmy v0.7.40 Pre-Release (2020-08-05)

We've added a lot in this pre-release:

• New post sorts Active (previously called hot), and Hot. Active shows posts with recent comments, hot shows highly ranked posts.
• Customizeable site icon and banner, user icon and banner, and community icon and banner.
• Added user preferred names / display names, bios, and cakedays.
• User settings are now shared across browsers (a page refresh will pick up changes).
• Visual / Audio captchas through the lemmy API.
• Lots of UI prettiness.
• Lots of bug fixes.
• Lots of additional translations.
• Lots of federation prepping / additions / refactors.

This release removes the need for you to have a pictrs nginx route (the requests are now routed through lemmy directly). Follow the upgrade instructions below to replace your nginx with the new one.
