- NvBuffer replaced with NvMap, which only manages the creation of raw nvmap objects. Users must map these objects manually to address spaces. - nvAddressSpaceBindToChannel removed. - nvChannelSetNvmapFd is now automatic and has been removed. - Nv3DContext, NvCmdList, NvErrorNotifier, NvGpfifo, NvGpu and NvZcullContext have all been removed. - Introduced NvGpuChannel, which provides all functionality that was part of said removed objects. - Other miscellaneous changes and fixes.
