Raspberry Pi 4 Gets A New, Feature-Packed Version Of Raspbian Called Buster
In addition to pulling a new Raspberry Pi 4 from the oven, the Raspberry Pi Foundation has cooked up a brand new version of its Raspberry Pi operating system, called Raspbian Buster. As the name implies, it is based on Buster, the latest version of Debian Linux (and named after the actual dog in Pixar's Toy Story movies).
Interestingly, Raspbian Buster is debuting slightly ahead of the official Debian release. The Raspberry Pi Foundation says this is because the open source OpenGL video driver is now being used by default, and it was developed using the most recent version of Debian.
"It would have been a lot of work to port everything required for it back on to Raspbian Stretch, so we decided that we would launch on Raspbian Buster—the only question was whether Buster would be ready before the hardware was!," the Raspberry Pi Foundation stated in a blog post.
It turns out it was not quite ready before the hardware—the official launch date for Buster is July 7 (incidentally, the same day AMD's Ryzen 3000 series desktop processors will hit retail, in unrelated news). Buster has sat in a "frozen" state for a couple of months, with only minor changes being made. That said, the version that is available now is "pretty much identical" to what is coming next week by Debian.
"There are no huge differences between Debian Stretch and Debian Buster. In a sad reflection of the way the world is nowadays, most of the differences are security changes designed to make Buster harder to hack. Any other differences are mostly small incremental changes that most people won’t notice," the Raspberry Pi Foundation said.

One thing the developers focused on with Buster is making it visually different from previous versions. The overall appearance of the desktop has remained largely the same for a few years now, and is a bit dated. So, Buster gets a "mild refresh" (think of it as a shot of Botox, as opposed to an all-out facelift).
In addition, Buster makes the Thonny Python development environment its default Python editor (IDLE is no longer included by default). For those who want an alternative, the Mu Python IDE is also still available in Recommended Software.
Other changes include tweaks to the taskbar, a new Screen Configuration tool when the GL driver is in use, hardware acceleration for the desktop environment (when using the new Raspberry Pi 4), a USB Attached SCSI Protocol (UASP) driver in place of the USB Mass Storage (UMS) driver, and a few other bits.
The Raspberry Pi Foundation does not recommend doing an in-place upgrade from an existing Stretch (or earlier) system to Buster, and instead says a new clean image is the best route. Follow this link to grab it.
