Back on 8 August there was evidently the Catalyst 14.8 Linux driver replace to succeed the Catalyst 14.6 Beta that was last updated in mid-July. AMD didn't make any announcement about the 14.8 Linux driver update and we didn't even notice until now when a Phoronix reader stumbled across Catalyst 14.8.
Unfortunately AMD didn't publish a change-log for the Catalyst 14.8 Linux driver update so we're really not sure what (if any) significant changes made it into this latest release, but we would certainly assume there's more Linux game bug-fixes to be found in this newest version. Given it was released at the end of last week, there's not OpenGL 4.5 support expected. It's also likely too soon to expect any Linux 3.16 kernel compatibility.
The Catalyst 14.8 Linux x86/x86_64 driver is marked as fglrx 14.201.1005 and can be found for download at AMD.com. Stay tuned for tests on Phoronix of this new driver and see what else we're able to uncover about its release.
