After a little less than six months of active development, after the release of first versioned release, the first major version is presented pleroma β federated social network for microblogging, written in the Elixir language and using the standardized W3C protocol Activity Pub. It is the second largest network in Fediverse..
Unlike its closest competitor, Mastodon, which is written in Ruby and relies on a large number of resource-intensive components, Pleroma is a high-performance server that can run on low-powered systems such as Raspberry Pi or cheap VPS.
Pleroma also implements the Mastodon API, allowing it to be compatible with alternative Mastodon clients such as tusky or fedilab. What's more, Pleroma ships with a fork of the source code for the Mastodon interface (or, to be more precise, the interface Glitch Social), making it smoother for users to navigate from Mastodon or Twitter to the TweetDeck interface. It is usually available at a URL like https://instancename.ltd/web.
Changes in this version:
- sending statuses with a delay / scheduled sending statuses (explanation);
- federated votes (supported by Mastodon and misskey);
- frontends now correctly save user settings;
- setting for secure private messages (post is sent only to the addressee at the beginning of the message);
- built-in SSH server for accessing settings via the protocol of the same name;
- LDAP support;
- integration with XMPP server MongooseIM;
- login with OAuth providers (for example, Twitter or Facebook);
- support for visualization of metrics using Prometheus;
- federated submission of user complaints;
- the initial version of the administrative interface (usually at a URL like https://instancename.ltd/pleroma/admin);
- support for emoji packs and tagging of emoji groups;
- Lots of internal changes and bug fixes.
