Release Notes

Cedar Aim app updates are usually automatic, via the Apple (iOS) or Google (Android) app store.

Hopper firmware updates must be applied by the user; see Updating for instructions.

Cedar Aim and Hopper firmware need not be updated in lock-step; newer versions of Cedar Aim can work with older versions of Hopper firmware and vice-versa. But it is best to keep both updated together to get the latest features and fixes.
