Microsoft's support forum says the updates are just for general "stability and quality improvements."
Once installed, the firmware version number should be 01078.00037.16082.410xx.
Keep in mind that this update may take a few days or even weeks to reach all owners of those phones, due to "phone model, region or network service provider" options. Currently, our UK variants are not seeing the update.
