Stadia Bluetooth upgrade deadline looms — officially at least

TL;DR

• Google killed off Stadia nearly three years ago, but released a Bluetooth upgrade for Stadia controllers.
• After pushing back its deadline for installing the Bluetooth firmware twice, today is looking like the last official day you’ll be able to use Google’s flashing tool.
• Even after Google takes its tool offline, third-party efforts have preserved the Bluetooth firmware and allow you to host the flashing tool yourself.
