Yes, with care. Mostly UI changes plus security fixes. If you're still on firmware older than 5.0.0, your settings won't carry over and the printer starts at factory settings, so note them first. Prusa recommends updating straight to 8.0.x instead.
⚠️ What breaks
Nothing explicitly breaking is flagged, but the notes mention migrations, deprecations or larger changes. Most setups upgrade fine. Back up first and update when you have time to check.
From the release notes
- Release notes: settings from firmware older than 5.0.0 are no longer migrated; updating directly from such a version starts the printer with factory settings.
- Release notes: the multi-material tool mapping screen is redesigned (Filament button becomes Details, Change becomes Remap).
- Release notes: includes security fixes; Prusa recommends going straight to 8.0.0, which contains everything in 7.0.0.
✅ What to do first
- Read the official release notes (linked in “What breaks”).
- Back up config and data (snapshot the VM/volume if you can).
- Note the version you are on now, so you can roll back.
- Update, then check logs and core functions before walking away.
