+title: Upgrading to a new release

+
+When a new version of Mastodon comes out, it appears on the [GitHub releases page](https://github.com/tootsuite/mastodon/releases). Please mind that running unreleased code from the `master` branch, while possible, is not recommended.
+
+Mastodon releases correspond to git tags. First, switch to the `mastodon` user:
+
+```sh
+su - mastodon
+```
+
+And navigate to the Mastodon root directory:
+
+```sh
+cd /home/mastodon/live
+```
+
+Download the releases's code, assuming that the version is called `v2.5.0`:
+
+```sh
+git fetch --tags
+git checkout v2.5.0
+```
+
+The release page contains a changelog, and below it, upgrade instructions. This is where you would execute them, for example, if the release mentions that you need to re-compile assets, you would execute:
+
+```sh
+RAILS_ENV=production bundle exec rails assets:precompile
+```
+
+After you have executed all special release-specific instructions, the last thing remaining is restarting Mastodon. *Usually* the streaming API is not updated, and therefore does not require a restart. Restarting the streaming API can lead to an unusually high load on the server, so it is advised to avoid it if possible.
+
+You would restart Sidekiq:
+
+```sh
+systemctl restart mastodon-sidekiq
+```
+
+And you would reload the web process to avoid downtime:
+
+```sh
+systemctl reload mastodon-web
+```
+
+**That's all!** You're running the new version of Mastodon now.
