Lemmy v0.19.6 Release

join-lemmy.org 2024-11-08 - Lemmy Release v0.19.6

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.

Changes

This release took a long time to complete due to a major performance problem which brought lemmy.ml to a crawl every time we tried to deploy the new version. It took a lot of testing (in production) to narrow it down to a single commit, and finally fix the problem.

The release itself contains numerous bug fixes and minor improvements:

Upgrade instructions

This upgrade could take as long as ~30 minutes for larger servers, due to needing to recalculate controversy ranks for all historical posts.

There are no breaking changes with this release.

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.

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.

Special shout out to @SleeplessOne1917, @phiresky, @dullbananas, @mv-gh, @Nothing4u, @asonix, @sunaurus, @flamingo-cant-draw, and @Freakazoid182 for their many code contributions and helpful insights.

Support development

We (@dessalines and @nutomic) have been working full-time on Lemmy for over five 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.

so, no need to resize images before upload on account of "image too large", lemmy will handle that?
- Nothing changed there. The image resolution changes have to do with thumbnails fetched from other sites or servers.
  
  how about adding the cutoff limit in the ui then? find myself shrinking and shrinking an image until it gets accepted and then promptly forgetting what the limit was.
  
  afaik this is configured in pictrs service and each instance has it set differently
