Mastodon 4.0 also improves multi-language support. Posts can now be translated from one language to another, using either DeepL or LibreTranslate behind the scenes, if the administrator running your server sets it up. You can also set preferred languages for trending status and links, and filter posts by language.

There are many other minor changes in the update. You can now directly upload HEIC, AVIF, and WebP files, instead of converting them manually first. The web interface also looks slightly different, matching the project’s current purple logo and color scheme, and changing the “Toot” button to “Publish.” Server administrators can also create roles and assign them to specific accounts, like roles in web forums or Discord servers.
