If you’ve been using Raspberry Pi’s single board computers since they were first introduced in 2012, then change should come as no surprise. The singleboard computer hardware has gone through several revisions as it offers more and more features. If you’ve been using the Raspbian operating system (OS), new releases have brought in their changes. In 2022, the OS changed its name to Raspberry Pi OS. Under the new name, it also released a beta 64-bit version.
