In 2013 the Chromecast was released. We rooted it pretty quickly and then every smart TV under the sun had casting ability five or so years later. Chromecast as a physical piece of hardware is now somewhat strange and used mostly for odd duck TVs and to actually use Netflix on a projector without a workaround.
The original Chromecast got an update for the first time in the 2020s… 9to5Google says the last update was over three years ago, but I can’t find when the last release was.
Bug fixes and improvements are all that is listed. They probably updated some security certificates at a minimum so they can get in to the devices later if they ever need to. No details though. I cannot locate my one remaining original Chromecast so I’m unable to tell if anything has actually changed.
This probably means Google takes the lead in the Android-ish device/product support category at nine years supported from the NVIDIA SHIELD which is at seven. Your move NVIDIA. You’ve just got to support the nearly perfect device three more years and hope Google doesn’t one-up you.[Google less than useful update list]
