According to the rather short release notes, the new RSCRE 17.10.3 driver only fixes crash or application hangs during the game launch in Wolfenstein II: The New Colossus on RX Vega graphics cards and a game crash or application hang during single player mission six in Destiny 2 on RX Vega series graphics cards.
The same release notes also list a couple of known bugs including a random system hang on configurations with 12 GPUs for compute workloads, which was strangely one of the big updates in the RSCRE 17.10.2 driver, issue with Assassin's Creed: Origins on Windows 7 OS, corruption in Forza Motorsport 7, issue with OverWatch, issue with high state GPU usage and clocks with Radeon ReLive and more. Hopefully, AMD will get to fix all those problems in the next WHQL driver release.
As always, you can find the new Radeon Software Crimson ReLive Edition 17.10.3 driver over at AMD's support page.
