Thanks to everyone

We'd like to thank our many contributors and users of Lemmy for coding, translating, testing, and helping find and fix bugs. We're glad many people find it useful and enjoyable enough to contribute.

Support development

We (@dessalines and @nutomic) have been working full-time on Lemmy for over three years. This is largely thanks to support from NLnet foundation, as well as donations from individual users.

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. A recurring donation is the best way to ensure that open-source software like Lemmy can stay independent and alive, and helps us grow our little developer co-op to support more full-time developers.

Here is an update that explains what we have been working on recently (apologies for not having these for a few months, summer vacations and all that). This should allow average users to keep up with development, without reading Github comments or knowing how to program.

@privacyguard added Single-Sign-On (SSO) support to lemmy (this still needs some UI work and testing, but the bulk of the work is done). Special thanks to Privacy Portal for working on this!

@carlos-cabello added a way to filter posts by title only (and not body) when searching.

@Freakazoid182 added custom emoji and tagline views.

@nothing4u made our scheduled cleanup job delete denied users.

@sunaurus made a few image proxy fixes.

@sleepless has been working hard on lemmy-ui-leptos, which may eventually replace lemmy-ui. He made improvements to how posts are displayed; made SI formatting consistent with how the current UI handles it; added translations; added post content actions, creator, and community listings; and made some plugins for markdown-it.

@nutomic cleaned up the issue tracker by closing invalid issues and adding tags like good first issue. He also made some simple improvements, like adding a category to RSS feeds, fixing an issue with activitypub ids, and removing the enable_nsfw setting in favor of content_warning.

@dessalines integrated a new rust clearurls library into lemmy that will remove tracking params for any post or comment text (Much thanks to @jendrikw for creating this library), increased the bio max length from 300 to 1000, removes lemmy's reliance on openssl, made the list logins response more uniform, added the ability to restore content on an unban, added a default comment sort type for both the local site, and your user.

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 v0.19.4 release is a big one, with > 200 pull requests merged since v0.19.3. As such we can only give a general overview of the major changes in this post, and without going into detail. For more information, read the full changelogs at the bottom of this post.

Local Only Communities

Communities have a new visibility setting, which can be either Public (current behaviour) or LocalOnly. The latter means that the community won't federate, and can only be viewed by users who are logged in to the local instance. This can be useful for meta communities discussing moderation policies of the local instance, where outside users shouldn't be able to participate. It is also a first step towards implementing private communities. Local only communities still need more testing and should be considered experimental for now.

Image Proxying

There is a new config option called image_mode which provides a way to proxy external image links through the local instance. This prevents deanonymization attacks where an attacker uploads an image to his own server, embeds it in a Lemmy post and watches the IPs which load the image.

Instead if image_mode is set to ProxyAllImages, image urls are rewritten to be proxied through /api/v3/image_proxy. This can also improve performance and avoid overloading other websites. The setting works by rewriting links in new posts, comments and other places when they are inserted in the database. This means the setting has no effect on posts created before the setting was activated. And after disabling the setting, existing images will continue to be proxied. It should also be considered experimental.

Many thanks to @asonix for adding this functionality to pict-rs v0.5.

Post hiding

You can now hide a post as a dropdown option, and there is a new toggle to filter hidden posts in lemmy-ui. Apps can use the new show_hidden field on GetPosts to enable this.

Moderation enhancements

With the URL blocklist admins can prevent users from linking to specific sites.

Admins and mods can now view the report history and moderation history for a given post or comment.

The functionality to resolve reports automatically when a post is removed was previously broken and is now fixed. Additionally, reports for already removed items are now ignored.

The site.content_warning setting lets admins show a message to users before rendering any content. If it is active, nsfw posts can be viewed without login.

Mods and admins can now comment in locked posts.

Mods and admins can also use external tools such as LemmyAutomod for more advanced tools.

Media

There is a new functionality for users to list all images they have previously uploaded, and delete them if desired. It also allows admins to view and delete images hosted on the local instance.

When uploading a new avatar or banner, the old one is automatically deleted.

Instance admins should also checkout lemmy-thumbnail-cleaner which can delete thumbnails for old posts, and free significant amounts of storage.

Federation

Lemmy can now federate with Wordpress, Discourse and NodeBB. So far there was only minor testing and these projects are still under heavy development. If you encounter any issues federating with these platforms, open an issue either in the Lemmy repo or in the respective project's issue tracker. You can test it by fetching the following posts:

• Wordpress
• Discourse
• NodeBB

In order to improve interoperability with Mastodon and other microblogging platforms, Lemmy now automatically includes a hashtag with new posts. The hashtag is based on the community name, so posts to /c/lemmy will automatically have the hashtag #lemmy. This makes Lemmy posts much easier to discover.

Reliability and security of federation have been improved, and numerous bugs squashed. Signed fetch was broken and is fixed now.

Vote display user setting

There is now a user setting to change the way vote counts are displayed, called vote display mode.

You can specify which of the following vote data you'd like to see (or hide): Upvotes, Downvotes, Score, Upvote Percentage, or none of the above. The default (based on user feedback) is showing the upvotes + downvotes.

App developers will need to update their apps to support this setting.

RSS Feeds

RSS feeds now include post thumbnail and embedded images.

Security Audit

A security audit was recently performed on Lemmy. Big thanks to Radically Open Security for the generous funding, and to Sabrina Deibe and Joe Neeman for carrying out the audit. The focus was on federation logic, and discovered various problems in this area. Most of the problems are being mitigated as part of this release. Fortunately no critical security vulnerabilities were discovered.

This is already the third security audit of Lemmy, all organized by ROS. We're greatly indebted to them for their support.

Other Changes

• Added Community local_subscribers count
• Support for custom post thumbnail
• For new user accounts the interface language and discussion languages are set automatically based on accept-language HTTP header
• Added instance-level default sort type
• Indicate to user when they are banned from community
• Added alt_text for image posts
• Dont require leading ! or @ to fetch a user or community
• Extra fields for PostReport and CommentReport views

Full Changelog

• API changes - lemmy-js-client 0.19.3 -> 0.19.4
• Lemmy Backend
• Lemmy-UI

Here is our regular update that explains what we have been working on for the past two weeks. This should allow average users to keep up with development, without reading Github comments or knowing how to program.

The last two weeks had these changes merged:

@Sleepless added a field so that users can see if they've been banned from a community. Has been refactoring Lemmy's exports to make them more easily used by 3rd party libraries, such as their lemmy-client-rs , and lemmy-ui-leptos. Added an animated avatar setting for users.

Has also been making improvements to lemmy-ui such as fixing a scroll bug, and hiding WYSIWYG buttons on preview. Has also been working a lot on lemmy-ui-leptos.

@Nutomic created an rfc for private communities, fixed an issue with the database logging connection URLs on an error. Added an optional site content warning and post-listing-mode. Also did a lot of code reviews.

@dullbananas fixed an issue with Comment Report reads, added better query plans, and is working on many DB improvements.

@dessalines added an instance-level default post sort. Added a maintenance task to clean up old denied users from the DB.. Made sure that blocking an instance also hides private messages from their users, to prevent harassment. He also added the ability to specify custom thumbnails for posts. Fixed an issue with auto-resolving reports when removing a post or comment.

Has also been making a lot of additions to Jerboa, such as admin registration applications, report queues, comment distinguishing, banning users from their profile page, privacy policies, and muted / smaller federated names.

@sunaurus created an rfc for separate report inboxes for mods and admins.

Here is our regular update that explains what we have been working on for the past two weeks. This should allow average users to keep up with development, without reading Github comments or knowing how to program.

The last two weeks were rather quiet, with only some minor changes merged:

@Elara6331 made improvements to the RSS feeds, adding thumbnails and filtering invalid characters. She also made a change to account creation, so that new accounts automatically have the correct interface language.

@iatenine increased the font sizes in lemmy-ui.

@Kradyz improved the message of the add mod dialog.

@dessalines has been adding more mod tools to jerboa: adding ban actions and viewing votes.

@Sleepless has been working on lemmy-ui-leptos, as well as creating a rust api library for lemmy called lemmy-client-rs.

This is a chance for any users, admins, or developers to ask anything they'd like to myself, @nutomic@lemmy.ml , SleeplessOne , or @phiresky@lemmy.world about Lemmy, its future, and wider issues about the social media landscape today.

NLNet Funding

First of all some good news: We are currently applying for new funding from NLnet and have reached the second round. If it gets approved then @phiresky@lemmy.world and SleeplessOne will work on the paid milestones, while @dessalines and @nutomic will keep being funded by direct user donations. This will increase the number of paid Lemmy developers to four and allow for faster development.

You can see a preliminary draft for the milestones. This can give you a general idea what the development priorities will be over the next year or so. However the exact details will almost certainly change until the application process is finalized.

Development Update

@ismailkarsli added a community statistic for number of local subscribers.

@jmcharter added a view for denied Registration Applications.

@dullbananas made various improvements to database code, like batching insertions for better performance, SQL comments and support for backwards pagination.

@SleeplessOne1917 made a change that besides admins also allows community moderators to see who voted on posts. Additionally he made improvements to the 2FA modal and made it more obvious when a community is locked.

@nutomic completed the implementation of local only communities, which don't federate and can only be seen by authenticated users. Additionally he finished the image proxy feature, which user IPs being exposed to external servers via embedded images. Admin purges of content are now federated. He also made a change which reduces the problem of instances being marked as dead.

@dessalines has been adding moderation abilities to Jerboa, including bans, locks, removes, featured posts, and vote viewing.

In other news there will soon be a security audit of the Lemmy federation code, thanks to Radically Open Security and NLnet.

The full description of the bug is in the linked issue above, but the short version is:

Our CreatePrivateMessageReport endpoint had a bug that would allow anyone, not just the recipient, to create a report, and then receive the details about private messages.

This allowed anyone to iterate over ids, creating thousands of reports in order to receive details about private messages.

Since those reports are visible to admins, it would be easy to discover if someone was abusing this, and luckily we haven't heard of anyone doing so on production instances (so far).

If you haven't, please be sure to upgrade to at least 0.19.1 for the fix.

Many thanks to @Nothing4You for finding this one.

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.

Here is our regular update that explains what we have been working on for the past two weeks. This should allow average users to keep up with development, without reading Github comments or knowing how to program.

Yesterday we released Lemmy 0.19.2, which included various federation fixes, as well as a way for admins to view votes.

@phiresky fixed a federation loop bug, and worked on lemmy-federation-state, a tool to help visualize federation status.

@sleepless fixed a lemmy-ui theming issue, as well as an issue with lemmy-ui's error pages.

@dessalines fixed an issue with resolving reports, added the ability for admins to view votes to prevent downvote trolling, upgraded our woodpecker-ci to 2.1, and helped fix various CI issues, and is adding comment and post removing to jerboa.

@nutomic is fixing an issue with mastodon follows, working on local-only communities, fixed an issue with the lemmy-stats-crawler, fixed an issue with cache-control headers, better handling of federated reports from mastodon and kbin, and much more.

@dullbananas is fixing up some Lemmy DB triggers, adding a better-organized cursor-based pagination library, and a query plan viewer.

Sometime early this morning, our database started having issues, most likely due to a disk corruption issue.

Unfortunately the postgres database was unrecoverable, and we had to restore from a nightly backup, so a few hours of posts and comments will be missing.

Apologies again for the downtime, and for the disruption.

Here is our regular update that explains what we have been working on for the past two weeks. This should allow average users to keep up with development, without reading Github comments or knowing how to program.

Last Friday we finally released Lemmy 0.19.0, after a long development time and extensive bug fixing. Read the announcement to find out about the major changes. A few days later on Wednesday we had to publish 0.19.1 to fix a few more bugs that slipped through.

@phiresky fixed the critical bug with outgoing federation in 0.19. Previously he fixed an authentication bug in lemmy-ui which was blocking the 0.19 release.

@dessalines fixed the broken logic for "hide read posts". He also fixed a problem with email login being case sensitive

@nutomic reenabled pushing to crates.io so Rust developers can easily interact with Lemmy. He also made performance optimizations for /api/v3/site and the optimized the Activitypub context sent by Lemmy, reducing the database size and the amount of data sent between instances. He fixed various tests to prevent random failures in continuous integration 1 2

@dullbananas has long been busy improving the database queries for Lemmy, such as fixing a bug in the way different posts sorts are combined, and improving the test cases.

This is our last update for 2023. It was a very busy year for Lemmy, and it looks like 2024 might have even more changes in store. So lets enjoy these holidays, have a Merry Christmas and Happy New Year!

Support development

We (@dessalines and @nutomic) have been working full-time on Lemmy for over three years. This is largely thanks to support from NLnet foundation, as well as donations from individual users.

This month we are running a funding drive with the goal of increasing recurring donations from currently €4.000 to at least €12.000. With this amount @dessalines and @nutomic can each receive a yearly salary of €50.000 which is in line with median developer salaries. It will also allow one additional developer to work fulltime on Lemmy and speed up development.

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 release is very large with almost 400 commits since 0.18.5. As such we can only give a general overview of the major changes in this post, and without going into detail. For more information, read the full changelog and linked issues at the bottom of this post.

Improved Post Ranking

There is a new scaled sort which takes into account the number of active users in a community, and boosts posts from less-active communities to the top. Additionally there is a new controversial sort which brings posts and comments to the top that have similar amounts of upvotes and downvotes. Lemmy's sorts are detailed here.

Instance Blocks for Users

Users can now block instances. Similar to community blocks, it means that any posts from communities which are hosted on that instance are hidden. However the block doesn't affect users from the blocked instance, their posts and comments can still be seen normally in other communities.

Two-Factor-Auth Rework

Previously 2FA was enabled in a single step which made it easy to lock yourself out. This is now fixed by using a two-step process, where the secret is generated first, and then 2FA is enabled by entering a valid 2FA token. It also fixes the problem where 2FA can be disabled without passing any 2FA token. As part of this change, 2FA is disabled for all users. This allows users who are locked out to get into their account again.

New Federation Queue

Outgoing federation actions are processed through a new persistent queue. This means that actions don't get lost if Lemmy is restarted. It is also much more performant, with separate senders for each target instance. This avoids problems when instances are unreachable. Additionally it supports horizontal scaling across different servers. The endpoint /api/v3/federated_instances contains details about federation state of each remote instance.

Remote Follow

Another new feature is support for remote follow. When browsing another instance where you don't have an account, you can click the subscribe button and enter the domain of your home instance in the popup dialog. It will automatically redirect you to your home instance where it fetches the community and presents a subscribe button. Here is a video showing how it works.

Authentication via Header or Cookie

Previous Lemmy versions used to send authentication tokens as part of the parameters. This was a leftover from websocket, which doesn't have any separate fields for this purpose. Now that we are using HTTP, authentication can finally be passed via jwt cookie or via header Authorization: Bearer <jwt>. The old authentication method is not supported anymore to simplify maintenance. A major benefit of this change is that Lemmy can now send cache-control headers depending on authentication state. API responses with login have cache-control: private, those without have cache-control: public, max-age=60. This means that responses can be cached in Nginx which reduces server load.

Moderation

Reports are now resolved automatically when the associated post/comment is marked as deleted. This reduces the amount of work for moderators. There is a new log for image uploads which stores uploader. For now it is used to delete all user uploads when an account is purged. Later the list can be used for other purposes and made available through the API.

Cursor based pagination

0.19 adds support for cursor based pagination on the /api/v3/post/list endpoint. This is more efficient for the database. Instead of a query parameter ?page=3, listing responses now include a field "next_page": "Pa46c" which needs to be passed as ?page_cursor=Pa46c. The existing pagination method is still supported for backwards compatibility, but will be removed in the next version.

User data export/import

Users can now export their data (community follows, blocklists, profile settings), and import it again on another instance. This can be used for account migrations and also as a form of backup. The export format is designed to remain unchanged for a long time. You can make regular exports, and if the instance becomes unavailable, register a new account and import the data. This way you can continue using Lemmy seamlessly.

Time zone handling

Lemmy didn't have any support for timezones, which led to bugs when federating with other platforms. This is now fixed by using UTC timezone for all timestamps.

ARM64 Support

Thanks to help from @raskyld and @kroese, there are now offical Lemmy releases for ARM64 available.

Activity now includes voters

• Previously, site and community activity counts were only based on people who commented, or posted. Those counts now include anyone who voted on a comment or post as well. Thanks to @Ategon for this change.

Upgrade instructions

Follow the upgrade instructions for ansible or docker. The upgrade should take less than 30 minutes.

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

Pict-rs 0.5 is also close to releasing. The upgrade takes a while due to a database migration, so read the migration guide to speed it up. Note that Lemmy 0.19 still works perfectly with pict-rs 0.4.

Thanks to everyone

We'd like to thank our many contributors and users of Lemmy for coding, translating, testing, and helping find and fix bugs. We're glad many people find it useful and enjoyable enough to contribute.

Here is our regular update that explains what we have been working on for the past two weeks. This should allow average users to keep up with development, without reading Github comments or knowing how to program.

This week we finally started deploying 0.19 release candidates to lemmy.ml, as a final testing step before release. Unfortunately there are some nasty authentication which we have been attempting to debug all week, without success so far. So it will take some more time to fix this and other issues before publishing the final version.

@rasklyd made Lemmy releases for ARM64 platforms possible. @kroese did the same for lemmy-ui. This means that official releases from Lemmy 0.19 will work on devices such as Raspberry Pi.

@dessalines has been very busy attempting to fix the previously mentioned authentication bug. He also worked on other bug fixes and upgraded Jerboa for Lemmy 0.19.

@nutomic again fixed various problems that were introduced during 0.19 development, to get ready for the release.

@Sleeplessone1917 implemented the frontend for user settings import/export. He also started work on an overhaul of context menus.

In anticipation of Lemmy's upcoming 0.19 release, and to work out any final issues, we're going to deploy a test release on lemmy.ml within the next few days.

We're doing this testing on lemmy.ml only, so that we can encounter any issues before the release, and to make sure the upgrade process is smooth for other production servers.

Some of the following will happen during the process:

• Apps will likely break (only for lemmy.ml)
• Lemmy.ml may experience some downtime for the upgrade to complete (ideally no more than an hour).
• If anything goes wrong, we may have to restore from a database backup, meaning content made in between backups may be lost.

If all goes well, we'll have an official announcement for the release after this testing period.

I apologize for the difficulties this might cause. At most this will be a week of hair-pulling, but its vital that we catch any issues before telling other servers to upgrade.

Some months have passed on since the Reddit blackout this June. It led to an explosive growth in Lemmy users, and lots of urgent work in scaling, bug fixes, user onboarding and more. Since then things have calmed down significantly, giving us breathing room and time to get more long-term work done.

As of Nov. 2023, Lemmy is at ~36k active daily users 🥳 (those who have posted or commented within the last month). While user counts are not an explicit goal of ours, this is still a tremendous achievement, and one which we can all be proud to be a part of. It shows that people truly do want alternatives to US tech companies, and will use them if they exist.

Join-Lemmy Redesign

Most recently we've been working on a redesign of join-lemmy.org to provide a better onboarding experience and cater towards new users. This includes:

• A helpful new instance picker to reduce choice overload.
• The instances page is now filterable, based a set of topics and languages, as well as sortable based on activity. The default sort is Random, to encourage people to join smaller servers.
• The apps page now has sections for Android, iOS, and web apps, as well as libraries. Feel free to do a pull request to add any apps that are missing.
• The donate page now shows the total amount of monthly donations across all platforms. More details below.
• The technology used is Typescript with tailwind and daisyUI CSS frameworks.

For server admins: If your instance isn't listed already, you must explicitly add your server topics and languages by doing a pull request to this file.

As you may have noticed, texts on the website are unchanged, and images on the main page are still generic placeholders. We are hoping for your contributions to improve them. For the texts, edit this file. Translations are managed via weblate. Images are located in this folder. If you are good with AI tools, consider replacing main_federation.webp and similar with more colorful images. More main_screen_x.webp images with custom themes or alternative frontends would be nice too. In general feel free to open issues or pull requests for improvements to the site.

Funding Drive

Before the Reddit migration, our income was almost exclusively made up of generous donations from the NLnet foundation. This funding was based on getting paid for implementing new features, specified in advance.

We've known that this funding could not last indefinitely, and that after several years of funding, NLnet's resources are better spent getting other projects up and running. Additionally, much of our time is spent on other equally important work: reviewing changes from community contributors, fixing bugs, doing support, and various organizational tasks.

That is why we are launching our first annual funding drive. The goal is to increase monthly, recurring donations from currently €4.000 to at least €12.000. With this amount @dessalines and @nutomic can each receive a yearly salary of €50.000 which is in line with median developer salaries. It will also allow one additional developer to work fulltime on Lemmy and speed up development.

Recurring donations from Lemmy users are the most sustainable solution for the future. It also means that we need to worry less about funding, and can focus more on improving Lemmy. And instead of being accountable to an external organization, we work directly for Lemmy's users. While one-time donations are also welcome, they are too unpredictable for long-term planning.

You can find available donation options on the donate page. This page was also updated during the redesign to display current donations and funding goals. If each active Lemmy user donated ~€0.33 per month it would be enough for 3 full-time developers. So please consider donating if you use Lemmy every day. Our preferred donation platform is Liberapay because it doesn't have any payment fees or delays, and is itself open source.

Besides Lemmy's developers, please consider donating to those who develop open-source apps or software for the Lemmy ecosystem, as well as server admins and moderation teams who are the backbone of the Lemmyverse. We would be happy to add donation links for the above to join-lemmy.org as well!

If you have any suggestions in regards to the topics mentioned in this post, please let us know. We also want to use this opportunity to thank the countless contributors who are working on Lemmy now.

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.

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!

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, 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.

The new major version of Lemmy is now ready, and we need your help with testing. Most importantly it uses HTTP for API requests now, which is much more efficient than websocket. Additionally Two-factor-auth is supported. There are also countless other improvements and bug fixes.

You can register on any of the following servers to start testing, no approval required. You can post to your hearts content to find out if anything is broken. The test instances only federate with each other to avoid affecting production instances with spam.

• Enterprise
• Voyager

If you encounter any bugs that aren't present in 0.17, open an issue and mention in the title that it happened with a release candicate version. Over the next days we will publish new RC versions to fix bugs that will invariably pop up.

Instance admins can try the new version by using Docker images dessalines/lemmy-ui:0.18.0-rc.2 and dessalines/lemmy:0.18.0-rc.1. Make sure that working backups are in place. For production instances its better to wait at least some days for the major issues to be fixed.

Its been a hectic week everyone, so I apologize that I haven't been as responsive as usual. We realized that we could either spend all our day answering questions, or coding to make lemmy better, so we're prioritizing the latter.

Reddit caught us right in the middle of one of our larger performance improvements, so I apologize for the instability of instances like this one. But I'm confident that lemmy will improve, especially due to all the new contributors helping out with performance, security fixes, and stability.

Please use our the issue trackers for the various lemmy projects to report issues, otherwise they will likely get lost.

Call for testers

• You can help us test patch releases like this one at https://enterprise.lemmy.ml
• We're readying the 0.18.0 release soon, you can help us test at https://voyager.lemmy.ml , and https://ds9.lemmy.ml
  • App devs should use voyager.lemmy.ml to test and prepare for 0.18.0, which should come in the next few weeks. The API changes and new types can be seen here.
  • 0.18.0 should give servers a big performance boost by removing websockets and switching entirely to HTTP. It also will add a lot of features like 2fa / TOTP.

Mostly bugfixes.

Changelog

Its been a long time coming 🥳 .

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.

We're getting ready to release a new version of Lemmy, which will require a database upgrade, so we'll have a few hours of downtime.

All the old pictures are restored from a backup, and should be working now. We've bought more hard drive space too, so we should be okay for a while.
