NVIDIA have released driver 550.142, and brief details are here:  https://www.nvidia.com/en-us/drivers/details/237853/  The ‘Release Highlights’ section is especially frugal on specifics..

The ‘softlink  / file not found’ error when compiling with Kernel 6.13 has finally been fixed (tested with 6.13-rc2):

It should be mentioned that the compilation of recent drivers still throws a _lot_ of warnings, including the ‘no previous prototype’ for multiple lines of code, and this one, repeated multiple times..

It would be nice if some attempt were made to clean these up, but at least the compilation completes successfully..
