There isn't much changed over the earlier beta with NVIDIA 515.48.07 simply being the first stable release. This includes the prior beta changes including the NVIDIA open kernel driver option -- but for consumer GPUs the proprietary kernel driver remains the default for now.
This NVIDIA R515 release also has support for the VK_EXT_external_memory_dma_buf and VK_EXT_image_drm_format_modifier extensions, NVIDIA installer updates, Valve Gamescope compositor handling work, systemd service file updates, and a variety of other mostly small fixes.
NVIDIA 515.48.07 is out today as the newest stable Linux driver to end out the month of May.
