Updates can address security and reliability
Keep supported devices current using normal manufacturer mechanisms.
Avoid unofficial firmware experiments
Replacing firmware can remove safety, support or ecosystem functions.
Update infrastructure too
Routers, hubs and bridges can affect many downstream devices.
Read major-change notes
A platform migration or architecture change deserves more preparation than a routine patch.
Keep in mind. Compatibility is not permanent. Confirm the current manufacturer, platform and certification information before purchasing, resetting or migrating a device.
