How to rebase
Current users can run bazzite-rollback-helper rebase stable for the latest stable, or bazzite-rollback-helper rebase 45.20261105 for this image specifically.
This build is an incremental stable refresh on the Fedora 45 line, not a new major Bazzite version.
Opinion: Fremont detection and anticheat handling are the headlines for Steam Machine / Deck users; CoolerControl Nvidia passthrough is the practical win if you fan-curve an Nvidia Bazzite box.
