Mastodon at a glance
Mastodon is self-hostable software for decentralized social networks that federates with other instances across the Fediverse using the ActivityPub protocol. Sysadmins deploy Mastodon to run their own servers for associations, companies, or communities, including user management, moderation, and integration with external storage and mail services. The application is built on Ruby on Rails and a Node.js streaming service and requires PostgreSQL and Redis.
New versions arrive as major and minor releases along with regular patch releases that frequently include security-relevant fixes. When upgrading, administrators should review the release notes for database migrations, changed dependencies, and any required configuration adjustments. Backing up the database and media storage before an upgrade is strongly recommended.
Because security updates are shipped promptly and older branches receive only limited maintenance, monitoring the official release channels is worthwhile. This helps plan maintenance windows and keep the instance on a supported release.
