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 fixes the problem of comment context not loading properly. It also fixes a couple other bugs.
## 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](https://join-lemmy.org/donate). 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.

## 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.

# Lemmy v0.18 Release (2023-06-23)
## 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
### HTTP API instead of Websocket
Until now Lemmy-UI used websocket for all API requests. This has [many disadvantages](https://github.com/LemmyNet/lemmy/issues/2841#issuecomment-1535469357), 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](https://lemmygrad.ml/u/CannotSleep420) and [@dessalines](https://lemmy.ml/u/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](https://github.com/LemmyNet/lemmy-ansible/pull/75) 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](https://f-droid.org/es/packages/org.shadowice.flocke.andotp/) or [Authenticator Pro](https://f-droid.org/packages/me.jmh.authenticatorpro/) 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](https://addons.mozilla.org/en-US/firefox/addon/pwas-for-firefox/).
#### 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:
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!
#### Share button
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](https://github.com/SleeplessOne1917), [alectrocute](https://github.com/alectrocute), [jsit](https://github.com/jsit), and many others for their great work on improving and re-organizing lemmy-ui.
#### Database optimizations
Special thanks to [johanndt](https://github.com/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](https://github.com/LemmyNet/lemmy-ansible#upgrading) or [docker](https://join-lemmy.org/docs/en/administration/install_docker.html#updating).
If you need help with the upgrade, you can ask in our [support forum](https://lemmy.ml/c/lemmy_support) or on the [Matrix Chat](https://matrix.to/#/#lemmy-admin-support-topics:discuss.online).
We (@dessalines and @nutomic) have been working full-time on Lemmy for almost three years. This is largely thanks to support from [NLnet foundation](https://nlnet.nl/).
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](https://join-lemmy.org/donate). 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 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
### 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](https://github.com/LemmyNet/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.
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](https://github.com/LemmyNet/lemmy/blob/main/config/defaults.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:
- 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.
- You can always find the latest version [here](https://github.com/LemmyNet/lemmy-ansible/blob/main/VERSION).
- 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](https://github.com/LemmyNet/lemmy-ansible/blob/main/templates/docker-compose.yml).
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](https://github.com/LemmyNet/lemmy/blob/main/docker/dev/docker-compose.yml#L88). 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](https://join-lemmy.org/docs/en/administration/backup_and_restore.html).
If you need help with the upgrade, you can ask in our [support forum](https://lemmy.ml/c/lemmy_support) or on the [Matrix Chat](https://matrix.to/#/#lemmy-admin-support-topics:discuss.online).
We (@dessalines and @nutomic) have been working full-time on Lemmy for almost three years. This is largely thanks to support from [NLnet foundation](https://nlnet.nl/).
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](https://join-lemmy.org/donate). 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 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 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](https://joinpeertube.org/)! Be aware that this requires Peertube [v4.2.0-rc.1](https://github.com/Chocobozzz/PeerTube/releases/tag/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](https://crates.io/crates/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](https://github.com/Nutomic/lemmyBB). Its in a very early stage,
so contributions are welcome!
In other development news, our test instances ([ds9.lemmy.ml](https://ds9.lemmy.ml/), [voyager.lemmy.ml](https://voyager.lemmy.ml/), [enterprise.lemmy.ml](https://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](https://join-lemmy.org/) and its instance list are also updated automatically every night.
## Upgrade notes
Follow the [Docker or Ansible upgrade instructions here.](https://join-lemmy.org/docs/en/administration/administration.html)
We (@dessalines and @nutomic) have been working full-time on Lemmy for almost two years. This is largely thanks to support from [NLnet foundation](https://nlnet.nl/).
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](https://join-lemmy.org/donate). 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?
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
### 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](https://github.com/LemmyNet/lemmy-ansible/pull/24/files) 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](https://join-lemmy.org/docs/en/client_development/theming.html).
### 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](https://sr.ht/~vpzom/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](https://lemmy.ml/post/184152) 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:
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](https://github.com/dessalines/jerboa), which is now on [F-Droid](https://f-droid.org/packages/com.jerboa) and [Google Play](https://play.google.com/store/apps/details?id=com.jerboa).
Follow the [Docker or Ansible upgrade instructions here.](https://join-lemmy.org/docs/en/administration/administration.html)
There are three lemmy.hjson config changes. See [defaults.hjson](https://github.com/LemmyNet/lemmy/blob/main/config/defaults.hjson) for comments and default values.
- changed boolean `email.use_tls` to `email.tls_type`
- added `setup.default_theme`
- added `federation.worker_count`

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](https://github.com/LemmyNet/Lemmy/issues/2003) and [Jaeger + opentelemetry](https://github.com/LemmyNet/Lemmy/issues/1992) to our dev setups, so we can better identify performance bottlenecks.
## What is Lemmy?
[Lemmy](https://join-lemmy.org/) 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.
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.
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.
## Upgrade notes
Follow the [Docker or Ansible upgrade instructions here.](https://join-lemmy.org/docs/en/administration/administration.html)
## Support development
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](https://join-lemmy.org/donate). 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.
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.

Almost one year after [first enabling federation](https://lemmy.ml/post/42833), 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](https://nlnet.nl/) for funding our full time work on Lemmy, and to [@lanodan](https://queer.hacktivis.me/users/lanodan) and [@asonix](https://masto.asonix.dog/@asonix) for helping to figure out how Pleroma and Mastodon federation works (it's difficult because they have almost no documentation).
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.
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.
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](https://github.com/LemmyNet/lemmy/blob/b18ea3e0cc620c3f97f9804c09b92f193809b846/config/config.hjson#L8-L12) 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](https://the-federation.info/)). 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](https://github.com/LemmyNet/lemmy/issues/868) 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.
The [`lemmy.hjson` `additional_slurs` field has changed its name to `slur_filter`. ](https://github.com/LemmyNet/lemmy/blob/b18ea3e0cc620c3f97f9804c09b92f193809b846/config/config.hjson#L8-L12)
Follow the [Docker or Ansible upgrade instructions here.](https://join-lemmy.org/docs/en/administration/administration.html)
## Lemmy-Ansible
We've now separated our ansible install method (the preferred way to deploy Lemmy) into its own repo, [lemmy-ansible](https://github.com/LemmyNet/lemmy-ansible). Let us know if you need help migrating existing installations over to it.

Since our last release in February, we've had [~150](https://github.com/LemmyNet/lemmy/compare/0.9.9...main) 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.
- A full list of the API changes can be seen on this diff of [lemmy-js-client: 0.9.9 -> 0.10.0](https://github.com/LemmyNet/lemmy-js-client/compare/0.9.9...0.10.0-rc.13) .

- Rewrote in inferno isomorphic, added i18n support via [weblate](https://weblate.yerbamate.ml/projects/lemmy/joinlemmy/).
- 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](https://github.com/LemmyNet/lemmy/blob/main/ansible/templates/config.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:
- 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](https://github.com/LemmyNet/lemmy-js-client/compare/0.9.9...0.10.0-rc.13) .
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.
- Added some active user counts, including `users_active_day`, `users_active_week`, `users_active_month`, `users_active_half_year` to `SiteAggregates` and `CommunityAggregates`. (Also added to lemmy-ui)
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/LemmurOrg/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.
- [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`.
- 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.
We've been working at warp speed since our `v0.7.0` release in June, adding over [870 commits](https://github.com/LemmyNet/lemmy/compare/v0.7.0...main) since then. :sweat:
- Split out i18n [lemmy-translations](https://github.com/LemmyNet/lemmy-translations), that any app or site developers can import and use. Lemmy currently supports [~30 languages!](https://weblate.yerbamate.ml/projects/lemmy/lemmy/)
- Documentation for [admins](https://join-lemmy.org/docs/administration_federation.html) and [devs](https://join-lemmy.org/docs/contributing_federation_overview.html) on how federation works
- It's now a fully isomorphic application using [inferno-isomorphic](https://infernojs.org/docs/guides/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.
We'd also like to thank both the [NLnet foundation](https://nlnet.nl/) for their support in allowing us to work full-time on Lemmy ( as well as their support for [other important open-source projects](https://nlnet.nl/project/current.html) ), [those who sponsor us](https://lemmy.ml/sponsors), and those who [help translate Lemmy](https://weblate.yerbamate.ml/projects/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.
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](https://enterprise.lemmy.ml/), [ds9](https://ds9.lemmy.ml/), [voyager](https://voyager.lemmy.ml/) ).
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](https://github.com/LemmyNet/lemmy/blob/main/config/defaults.hjson#L60) 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](https://voyager.lemmy.ml/search/q/!main%40ds9.lemmy.ml/type/All/sort/TopAll/page/1).
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`
We've [added a lot](https://github.com/LemmyNet/lemmy/compare/v0.7.40...v0.7.0) 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.
- 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](https://radical.town/@felix). Theyve created a better documentation system, implemented RSS feeds, simplified docker and project configs, upgraded actix, working on federation, a whole lot else.
