While it was the launch of the Raspberry Pi 4 that snagged all the headlines this week, it wasn't the only new product to come out of the Raspberry Pi Foundation. The not-for-profit also released a new version of its Raspbian Linux distribution, dubbed 'Buster.' You need Buster to run Raspberry Pi 4, but it also works on and improves the experience for any older Raspberry Pi.
