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 fixes a security vulnerability which allows an attacker to delete images uploaded by other users. You can read the details in the security advisory. Thanks to @Nothing4You for discovering and fixing it.

A new donation dialog is shown to users once per year, to help fund Lemmy development.

There are also various backports from the development branch. Importantly the "Private instance" setting can now be used with federation enabled. This way only logged-in users can browse posts and comments, which stops AI crawlers from overloading the server. Also moderators can now view votes in the post/comment options.
