As reported by Phoronix, the Haiku operating system
"has added (untested) support for the newest AMD Radeon graphics cards
to its open-source driver for the BeOS-compatible operating system." (Specifically, that support is for the "Mullins" and "Hawaii" graphics processors.) Impressive that this project keeps the BeOS flag raised and continues to modernize; Haiku has been around since 2001 — years longer than Be, Inc.
