+# Lemmy Release 0.14.0: Federation with Mastodon and Pleroma (2021-11-17)
+
+Today is an exciting day for the Lemmy project.
+
+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).
+
+
+## Major Changes
+
+### Federation code rewrite
+
+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. 
+
+Mastodon and Pleroma users can:
+
+- View Lemmy communities, user profiles, posts and comments
+- Follow Lemmy communities to receive new posts and comments
+- Replies (mentions) work in both directions, including notifications
+
+In addition, Pleroma users can exchange private messages with Lemmy users.
+
+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.
+
+### Hardcoded slur filter removed
+
+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.
+
+```
+curl https://your-instance.com/api/v3/site | jq -c .federated_instances.linked
+```
+
+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.
+
+## Changes
+
+### API
+
+- There is now a `GetUnreadCount` in the API to check the count of your unread messages, replies, and mentions.
+- A full list of the API changes can be seen on this diff of [lemmy-js-client: 0.13.0 -> 0.14.0-rc.1](https://github.com/LemmyNet/lemmy-js-client/compare/0.13.0...0.14.0-rc.1) .
