  • The update "merges support for both Surface Pro X SQ1 and SQ2 devices" in several areas.

Microsoft's Surface Pro X recently received a firmware update. Specifically, the update is for the Surface Pro X with an SQ2 processor, which is also referred to as the Surface Pro X (2020). As is normally the case, the firmware update doesn't include any new features. It does, however, include several improvements.

This update appears to mark a merging of support for the Surface Pro X with SQ1 and SQ2 processors in several areas. Several items in the changelog state, "Improves system stability and merges support for both Surface Pro X SQ1 and SQ2 devices." This seems to imply that going forward, changes will roll out to both devices together, at least for the items mentioned.
