Raw Blame History

Lemmy v0.18.3 Release (2023-07-28)

What is Lemmy?

Lemmy is a self-hosted social link aggregation and discussion platform. It is completely free and open, and not controlled by any company. This means that there is no advertising, tracking, or secret algorithms. Content is organized into communities, so it is easy to subscribe to topics that you are interested in, and ignore others. Voting is used to bring the most interesting items to the top.

Major Changes

This version brings major optimizations to the database queries, which significantly reduces CPU usage. There is also a change to the way federation activities are stored, which reduces database size by around 80%. Special thanks to @phiresky for their work on DB optimizations.

The federation code now includes a check for dead instances which is used when sending activities. This helps to reduce the amount of outgoing POST requests, and also reduce server load.

In terms of security, Lemmy now performs HTML sanitization on all messages which are submitted through the API or received via federation. Together with the tightened content-security-policy from 0.18.2, cross-site scripting attacks are now much more difficult.

Other than that, there are numerous bug fixes and minor enhancements.

Support development

@dessalines and @nutomic are working full-time on Lemmy to integrate community contributions, fix bugs, optimize performance and much more. This work is funded exclusively through donations.

If you like using Lemmy, and want to make sure that we will always be available to work full time building it, consider donating to support its development. No one likes recurring donations, but they’ve proven to be the only way that open-source software like Lemmy can stay independent and alive.

Lemmy v0.18.1 Release (2023-07-07)

What is Lemmy?

Major Changes

This release includes major improvements to performance, specifically optimizations of database queries. Special thanks to @phiresky, @ruud, @sunaurus and many others for investigating these. Additionally this version includes a fix for another cross-site scripting vulnerability. For these reasons instance admins should upgrade as soon as possible.

As promised, captchas are supported again. And as usual there are countless bug fixes and minor improvements, many of them contributed by community members.

Upgrade instructions

Follow the upgrade instructions for ansible or docker.

If you need help with the upgrade, you can ask in our support forum or on the Matrix Chat.

Lemmy v0.18 Release (2023-06-23)

What is Lemmy?

Major Changes

HTTP API instead of Websocket

Until now Lemmy-UI used websocket for all API requests. This has many disadvantages, like making the code harder to maintain, and causing live updates to the site which many users dislike. Most importantly, it requires keeping a connection open between server and client at all times, which causes increased load and makes scaling difficult. That's why we decided to rip out websocket entirely, and switch to HTTP instead. This change was made much more urgent by the sudden influx of new users. @CannotSleep420 and @dessalines have been working hard for the past weeks to implement this change in lemmy-ui.

HTTP on its own is already more lightweight than websocket. Additionally it also allows for caching of server responses which can decrease load on the database. Here is an experimental nginx config which enables response caching. Note that Lemmy doesn't send any cache-control headers yet, so there is a chance that private data gets cached and served to other users. Test carefully and use at your own risk.

Two-Factor Authentication

New support for two-factor authentication. Use an app like andOTP or Authenticator Pro to store a secret for your account. This secret needs to be entered every time you login. It ensures that an attacker can't access your account with the password alone.

Custom Emojis

Instance admins can add different images as emojis which can be referenced by users when posting.

Other changes

Progressive Web App

Lemmy's web client can now be installed on browsers that support PWAs, both on desktop and mobile. It will use an instance's icon and name for the app if they are set, making it look like a given instance is an app.

Note for desktop Firefox users: the desktop version of Firefox does not have built in support for PWAs. If you would like to use a Lemmy instance as a PWA, use use this extension.

Error Pages

Lemmy's web client now has error pages that include resources to use if the problem persists. This should be much less jarring for users than displaying a white screen with the text "404 error message here".

Route Changes

Pages that took arguments in the route now take query parameters instead. For example, a link to lemmy.ml's home page with a few options used to look like this:

https://lemmy.ml/home/data_type/Post/listing_type/All/sort/Active/page/1

The new route would look like this:

https://lemmy.ml?listingType=All

Note that you now only have to specify parameters you want instead of all of them.

Searchable select redesign

The searchable selects, such as those used on the search page, have a new look and feel. No more inexplicable green selects when using the lightly themes!

Posts on the web client now have a share button on supported browsers. This can be used to share posts to other applications quickly and easily.

Lemmy-UI Overall look and feel

lemmy-ui is now upgraded to bootstrap 5, and every component is now much cleaner.

Special thanks to sleepless, alectrocute, jsit, and many others for their great work on improving and re-organizing lemmy-ui.

Database optimizations

Special thanks to johanndt, for suggesting improvements to Lemmy's database queries. Some of these suggestions have already been implemented, and more are on the way.

Query speed is Lemmy's main performance bottleneck, so we really appreciate any help database experts can provide.

Captchas

Captchas are not available in this version, as they need to be reimplemented in a different way. They will be back in 0.18.1, so wait with upgrading if you rely on them.

Upgrade instructions

The installation instructions have been slightly updated. However there are no breaking changes, other than removing websocket.

Follow the upgrade instructions for ansible or docker.

If you need help with the upgrade, you can ask in our support forum or on the Matrix Chat.

Support development

We (@dessalines and @nutomic) have been working full-time on Lemmy for almost three years. This is largely thanks to support from NLnet foundation.

If you like using Lemmy, and want to make sure that we will always be available to work full time building it, consider donating to support its development. No one likes recurring donations, but they've proven to be the only way that open-source software like Lemmy can stay independent and alive.

Changes

API

Our HTTP API docs are at https://join-lemmy.org/api/
- These are now auto-generated directly from our rust type definitions, using ts-rs.
- A comparison from the last release
There are two breaking changes since the last release:
- GetSite.taglines is now required, and is an empty array.
- SortType and ListingType are now numbered enums, rather than strings in some places, and numbers in others.

Config

No changes, but you can see the current config options here.

Lemmy v0.17.0 Release (2023-01-31)

What is Lemmy?

Major Changes

Language Tags

Content can now be tagged to indicate the language it is written in. These tags can be used to filter content, so that you only see posts in languages which you actually understand. Instances and communities can also specify which languages are allowed, and prevent posting in other languages.

In the future this will also allow for integrated translation tools.

Comment trees

Lemmy has changed the way it stores comments, in order to be able to properly limit the comments shown to a maximum depth.

Included are proper comment links (/comment/id), where you can see its children, a count of its hidden children, and a context button to view its parents, or the post.

Featured posts

Admins and mods can now "feature" (this used to be called "sticky" ala reddit) posts to the top of either a community, or the top of the front page. This makes possible announcement and bulletin-type posts.

Special thanks to @makotech for adding this feature.

Federation

Lemmy users can now be followed. Just visit a user profile from another platform like Mastodon, and click the follow button, then you will receive new posts and comments in the timeline.

Votes are now federated as private. This prevents other platforms from showing who voted on a given post, and it also means that Lemmy now counts votes from Mastodon.

This release also improves compatibility with Pleroma. If you previously had trouble interacting between Pleroma and Lemmy, give it another try.

We've extracted the main federation logic into its own library, activitypub-federation-rust. It is open source and can be used by other projects to implement Activitypub federation, without having to reinvent the wheel. The library helps with handling HTTP signatures, sending and receiving activities, fetching remote objects and more.

Other changes

Admins can now purge content and pictures from the database.
Mods can distinguish a comment, "stickying" it to the top of a post. Useful for mod messages and announcements.
Number of new / unread comments are now shown for each post.
Lemmy now automatically embeds videos from Peertube, Youtube and other sites which provide an embed link via Opengraph attribute.
You can give your site "taglines", short markdown messages, which are shown at the top of your front page. Thanks to @makotech for adding this.
You can now report private messages.
Most settings have been moved from the config file into the database. This means they can be updated much easier, and apply immediately without a restart.
When setting up a new Lemmy instance, it doesn't create a default community anymore. Instead this needs to be done manually.
Admins can choose to receive emails for new registration applications.
An upgrade of diesel to v2.0, our rust -> postgres layer.
Too many bugfixes to count, they are listed below.

Upgrade instructions

This upgrade requires a newer version of postgres, which must be done manually. Do not try to use Ansible.

cd to your lemmy docker directory which can be found in /srv/lemmy/(domainname) and run this helper script:

sudo wget https://raw.githubusercontent.com/LemmyNet/lemmy/main/scripts/postgres_12_to_15_upgrade.sh
sudo sh postgres_12_to_15_upgrade.sh

This script saves a copy of your old database as 12_15.dump.sql. Do not delete this file until you've followed all the instructions below, and the upgrade is complete.

Next, manually edit your lemmy.hjson to account for a few breaking changes:

pictrs_url is removed, and the pictrs config is now a block. If using docker, it should look like:
```
pictrs: {
  url: "http://pictrs:8080/"
  api_key: "{{ postgres_password }}"
}
```
The rate_limit, federation, captcha, and slur_filter blocks should be removed, as they are now in the database, and can be updated through the UI.
The site setup has removed a few fields.
See the link above for every setting.

Next, edit your docker-compose.yml file to use the newer version of lemmy and lemmy-ui.

The image lines should look like:

image: dessalines/lemmy:0.17.0 for lemmy
image: dessalines/lemmy-ui:0.17.0 for lemmy-ui

The lemmy-ui environment variables have changed, and should now look like:

  environment:
    - LEMMY_UI_LEMMY_INTERNAL_HOST=lemmy:8536
    - LEMMY_UI_LEMMY_EXTERNAL_HOST={{ domain }}
    - LEMMY_UI_HTTPS=true

You can always find the latest version here.
Ensure that postgres is postgres:15-alpine (the upgrade script above should have already set this correctly)

If you're having any problems, your docker-compose.yml should look similar to the one from the lemmy-ansible repo.

Finally, run sudo docker-compose up -d, and wait for lemmy to start up.

Note: On production databases with thousands of comments, this upgrade takes several hours. If your system has problems upgrading, or you'd like to speed up the upgrade, consider tuning your postgres database using the instructions here. If not, just wait for the database migrations to complete, as this large migration of the comment table only ever needs to be run once.

Note: If you have any issues upgrading, you can restore your old database using the backup and restore instructions here.

If you need help with the upgrade, you can ask in our support forum or on the Matrix Chat.

Support development

We (@dessalines and @nutomic) have been working full-time on Lemmy for almost three years. This is largely thanks to support from NLnet foundation.

If you like using Lemmy, and want to make sure that we will always be available to work full time building it, consider donating to support its development. No one likes recurring donations, but they've proven to be the only way that open-source software like Lemmy can stay independent and alive.

Lemmy v0.16.4 Release : Peertube federation, Rust API and other improvements (2022-05-27)

What is Lemmy?

Major changes

This version adds a new community setting "restricted". If this is active, only moderators can post in the community (but anyone can comment). This can be useful for announcements or blogs.

In your site settings there is a new field for legal information. This can be used to present terms of service, privacy policy etc.

We've also added an admin setting for the default post listing type. This determines whether users without login, and newly registered users, will see the Local or All timeline by default.

HTML tags are now disabled in markdown, as the were causing some issues.

Federation

Lemmy now federates with Peertube! Be aware that this requires Peertube v4.2.0-rc.1 or later. You can now follow Peertube channels from Lemmy and comment on videos. If there is other functionality that you would like to see federated, please open an issue (the same goes for federation with other projects).

When browsing remote Lemmy communities, you will now see the site description and rules in the sidebar. Some federated actions did not generate mod log entries previously, this has been fixed. Also, federation with Friendica was approved, Lemmy now correctly receives comments with hashtags. Additionally, the previous version had a check which rejected federation in case the domain of user avatars or banners didn't match the user's domain. This check broke federation with some instances, and was removed.

Rust API

If you are thinking of developing a Rust application which interacts with Lemmy, this is now much easier. The lemmy-api-common crate has a new feature which disables all heavy dependencies (like diesel) by default. You can add the crate to your project, and interact with Lemmy API using the exact same structs that Lemmy itself uses. For an example, have a look at lemmyBB. Its in a very early stage, so contributions are welcome!

In other development news, our test instances (ds9.lemmy.ml, voyager.lemmy.ml, enterprise.lemmy.ml) are now updated automatically every night with the latest development version. This should make it easier for admins and users to test new features before they are released. At the same time, join-lemmy.org and its instance list are also updated automatically every night.

Upgrade notes

Follow the Docker or Ansible upgrade instructions here.

Support development

We (@dessalines and @nutomic) have been working full-time on Lemmy for almost two years. This is largely thanks to support from NLnet foundation.

If you'd like to support development, and make sure that we will always be available to work full time on Lemmy, consider donating to support its development. We've spent hundreds of hours on Lemmy, and would like to be able to add more developers to our little open-source co-op as time goes on.

Lemmy v0.16.0 Release: Theming and Federation improvements (2022-03-08)

What is Lemmy?

Major Changes

Theming

Customizing Lemmy is now much easier than before. Instance admins can select a default instance theme under /admin which applies to all users who are not logged in, and those who haven't explicitly picked a theme.

It is also possible now to add custom themes to an instance, without having to recompile lemmy-ui. When running with Docker, make sure that these lines are present in docker-compose.yml (Ansible will add them automatically if you updated the repo). Then put your .css file into ./volumes/lemmy-ui/extra_themes. The new theme can then be selected by users, or set as instance default.

For native installation (without Docker), themes are loaded by lemmy-ui from ./extra_themes folder. A different path can be specified with LEMMY_UI_EXTRA_THEMES_FOLDER environment variable.

For instructions how to create a new theme, have a look at the documentation.

Federation

@nutomic made many changes to federation to increase compatibility with other software. Lemmy can now receive deletions from [Pleroma], comments from [Friendica] and communities from lotide. Other actions were already compatible before. Mastodon can now display communities even when a user with identical name exists (but the user can't be viewed in that case). There were no breaking changes necessary, so federation is fully compatible with 0.15. If you notice something in another project that doesn't federate but should, please open an issue.

Multiple users have pointed out that posts, comments and votes don't federate reliably. We first attempted to fix this in Lemmy 0.15.4 a few days ago, but that didn't help much. Later @nutomic noticed that Lemmy was only sending out activities with 4 worker threads, which is not enough for a big instance like lemmy.ml. At the same time, many of those workers were taken up by sending to broken instances, trying to connect for a minute or more. This version adds a timeout and increases the number of workers.

Federated bans

Until now, only community bans were federated, and the "Remove content" option didn't work over federation. The new version fixes this behaviour, so that both site bans and community bans federate, including "Remove content" option and expiry. Note that this change only affects new bans, those which were issued before upgrading to 0.16 will not be federated.

Hide communities

@dayinjing implemented a funcionality for instance admins to hide controversial communities. A hidden community is only visible to those users who subscribe to it. This represents a milder alternative to removing a community. This functionality is not implemented in lemmy-ui yet, but admins can hide a community like this via command line:

curl -X PUT https://example.com/api/v3/community/hide \
    -H "Content-Type: application/json" \
    -d \
    '{"community_id":3,"hidden":true,"reason":"*reason for mod log*","auth":"*admin jwt token*"}'

Jerboa: a new android app

To help adoption, and since most people use social media through their smartphones nowadays, @dessalines has been working on a native android app for Lemmy called Jerboa, which is now on F-Droid and Google Play.

It is still at an alpha level, but is very usable. We'd love to have experienced android developers contribute to it.

This now makes three smartphone apps for Lemmy: Lemmur and Jerboa for Android, and Remmel for iOS.

Upgrade notes

Follow the Docker or Ansible upgrade instructions here.

There are three lemmy.hjson config changes. See defaults.hjson for comments and default values.

changed boolean email.use_tls to email.tls_type

Lemmy now has private instances, optional registration applications, optional email verification, and temporary bans! These are described in detail below.

Special thanks to @asonix for adding tokio-console and Jaeger + opentelemetry to our dev setups, so we can better identify performance bottlenecks.

What is Lemmy?

Lemmy is similar to sites like Reddit, Lobste.rs, or Hacker News: you subscribe to communities you're interested in, post links and discussions, then vote and comment on them. Lemmy isn't just a reddit alternative; its a network of interconnected communities ran by different people and organizations, all combining to create a single, personalized front page of your favorite news, articles, and memes.

Major Changes

Required email verification

Admins can turn this on, and new users will need to verify their emails. Current users will not have to do this.

Registration applications

Admins can now optionally make new users fill out an application to join your server. There is a new panel in their top bar where they can approve or deny pending applications.

This works in conjunction with the require_email field. If that is also turned on, the application will only be shown after their email has been verified. The user will receive an email when they have been accepted.

Closed / Private instances

The instance settings now includes a private instance option, which if turned on, will only let logged in users view your site. Private instances was one of our first issues, and it was a large effort, so its great to finally have this completed.

Temporary Bans

When banning users from your site or community, moderators can now optionally give a number of days for the ban to last.

Allow comment replies from blocked users

It used to be that if a user blocked you, you couldn't respond to their public posts and comments. This is now fixed. They won't see your content, but others can.

Changes

API

We've removed a list of banned users from GetSite, added a few endpoints related to registration applications, made a few changes allowing temporary bans, site settings, made a few changes to the login response. These are non-destructive and current clients should work with this release.

A full list of the API changes can be seen on this diff of lemmy-js-client: 0.14.0 -> 0.15.0 .

Config

There is a new rate limit for creating new comments in the config.hjson.

Lemmy Release v0.14.0: Federation with Mastodon and Pleroma (2021-11-17)

Today is an exciting day for the Lemmy project.

Almost one year after first enabling federation, we now federate with other projects for the first time! According to some people's definition, this finally makes us part of the Fediverse.

It took a lot of work to make this possible, so big thanks to NLnet for funding our full time work on Lemmy, and to @lanodan and @asonix for helping to figure out how Pleroma and Mastodon federation works (it's difficult because they have almost no documentation).

Major Changes

Federation code rewrite

The rewrite of the federation code started by @nutomic in August is now mostly complete. As a result, the code is much cleaner, and has tests to guarantee no breaking changes between Lemmy versions. As a side effect of this rewrite, it was now relatively easy to enable federation with other projects.

Mastodon and Pleroma users can:

View Lemmy communities, user profiles, posts and comments
Follow Lemmy communities to receive new posts and comments
Replies (mentions) work in both directions, including notifications

In addition, Pleroma users can exchange private messages with Lemmy users.

Note that Pleroma and Mastodon rely on a compatibility mode in Lemmy, which means that they won't receive events like Deletes or Votes. Other projects whose federation works similar to Pleroma/Mastodon will likely also federate.

Hardcoded slur filter removed

Lemmy finally has essential moderation tools (reporting, user/community blocking), so the hardcoded filter isn't necessary anymore. If you want to keep using the slur filter, copy these lines to your config file when upgrading, and adjust to your liking.

Upgrade notes

Federation with Pleroma/Mastodon works automatically, you don't need to change anything, assuming that your allowlist/blocklist configuration permits it.

Note that Mastodon and Pleroma are much, much bigger than Lemmy at this point, with a combined 3 milion users and 4500 instances, compared to 20.000 users and 35 instances for Lemmy (source). The existing mod tools in Lemmy might not be adequate to handle that at the moment.

Be aware that if you have federation enabled in the Lemmy config, Mastodon and Pleroma users can now fetch all posts and comments, to view them and share with their followers. The Lemmy blocklist/allowlist can not prevent this, it only prevents posts/comments from blocked instances to be shown on your own instance. The only solution to this problem is disabling federation, or waiting for signed fetch to be implemented.

If you want to use federation, but review new instances before federating with them, use the allowlist. You can switch from open federation to allowlist federation by pasting the output of the command below into federation.allowed_instances in the Lemmy config.

curl https://your-instance.com/api/v3/site | jq -c .federated_instances.linked

The lemmy.hjson additional_slurs field has changed its name to slur_filter.

Follow the Docker or Ansible upgrade instructions here.

Lemmy-Ansible

We've now separated our ansible install method (the preferred way to deploy Lemmy) into its own repo, lemmy-ansible. Let us know if you need help migrating existing installations over to it.

Changes

API

There is now a GetUnreadCount in the API to check the count of your unread messages, replies, and mentions.
A full list of the API changes can be seen on this diff of lemmy-js-client: 0.13.0 -> 0.14.0-rc.1 .

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.org, 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.org

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:

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.

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.

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

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.

chmod +x migrate-pictshare-to-pictrs.bash
sudo bash migrate-pictshare-to-pictrs.bash

Note: After upgrading, all users need to reload the page, then logout and login again, so that images are loaded correctly.

Lemmy v0.6.0 Release (2020-01-16)

v0.6.0 is here, and we've closed 41 issues!

This is the biggest release by far:

Avatars!
Optional Email notifications for username mentions, post and comment replies.
Ability to change your password and email address.
Can set a custom language.
Lemmy-wide settings to disable downvotes, and close registration.
A better documentation system, hosted in lemmy itself.
Huge DB performance gains (everthing down to < 30ms) by using materialized views.
Fixed major issue with similar post URL and title searching.
Upgraded to Actix 2.0
Faster comment / post voting.
Better small screen support.
Lots of bug fixes, refactoring of back end code.

Another major announcement is that Lemmy now has another lead developer besides me, @felix@radical.town. Theyve created a better documentation system, implemented RSS feeds, simplified docker and project configs, upgraded actix, working on federation, a whole lot else.
