Some of the improvements that were incorporated were support in conjunction with the Linux 5.5 Kernel in the DisplayPort Multi-Stream Transport (DP MST), several video fixes, a bug fix in DXVK in relation to the compilation of shaders that were in a loop infinity and a new PRIME Synchronization as seen in the other releases of the 440 series of the driver.
The other news and improvements were:
Disabled frame rate limit for configurations without active screens when HardDPMS is enabled.
Restricted the maximum number of screens per GPU device, to prevent the X server from crashing when more than one GPU screen is configured for a single device.
Fixed a bug that could cause the X server to crash when exiting DPMS with HardDPMS enabled.
Added a standard file when saving the file for video configuration in nvidia-settings if it is not detected.
Added support for audio through DisplayPort Multi-Stream. This support requires Linux kernel version 5.5 or later.
Updated the NVIDIA driver to allow high definition audio controllers NVIDIA (HDA) respond to display hotplug events while the HDA is suspended at run time.
Fixed a bug that caused titles DXVK infinite loop during compilation of the shader, if no OpSource instructions were present.
Sync support added PRIME for the kernel Linux 5.4 and later.

Well, now wait for the arrival of the 440.59 driver in the Linux distros repositories, if not already in some. But I'm really excited to be able to test with the Ubuntu 20.04 LTS, which in my view, will be a very good edition for hybrid notebooks.
