The MagSafe Charger has received another update, but it isn't clear what it is for.
Nearly every tech accessory has firmware, and the MagSafe Charging puck is no exception. Apple provides updates to accessories like this in the background with no release notes or any way to push the update manually.
According to a tweet from iSoftware Updates, the new firmware is version 10M3761, up from version 10M1821. The update will install automatically when the MagSafe Charger is in use and connected to power, though the user will not be notified of any change.
It isn't clear what this update is for. Apple hasn't released any new products that is compatible with the MagSafe charger. It could be a bug fix update or provide improved compatibility with products like AirPods Pro 2.
