While the Catalyst driver for Windows was released a number of
days ago, the Catalyst Linux driver was missing. It has, however, been
released today. AMD's Linux engineers ended up delaying the Catalyst 9.3
release so they could spend additional time tuning this driver, since it
will be the last release that supports the R300 through R500 series as
the support is being dropped. The significant feature that was pushed
back into the Catalyst 9.3 Linux driver is improved Composite support.
