According to the rather short release notes, the new Geforce 378.57 hotfix driver fixes crashes in Minecraft and some other Java-based titles as well as resolving the "Debug Mode" default option on Pascal-based GPUs.
As was the case with earlier hotfix drivers, this one also brings all the fixes, optimizations and support from earlier drivers so in case you are playing Minecraft or running any Pascal GPU, it should be wise to update your drivers.
The new Geforce 378.57 hotfix driver is available directly from Nvidia's support page and is available for Windows 10 and Windows 8.1/7 OS in both 32-bit and 64-bit options.
