They’ll be released as/when they are ready. The packages likely haven’t been updated because they’re not ready yet. There is no public ETA.
For the CUDA APT repository, NVIDIA have not published updated packages. I assume that these packages are still undergoing development and/or quality-assurance, particularly given some of the packagingfeedback flagged up after the beta release and reported in the main 565 driver-series thread.
Debian, not NVIDIA, are responsible for the contents of the deb.debian.org package archive. There is generally a non-trivial delay between NVIDIA publishing new major driver versions and Debian incorporating them into their distribution and publishing updated versions. The nvidia-graphics-drivers tracker page describes the recent history of these packages and links to other relevant resources if you’d like to know more.
Bear in mind that Debian is a community-developed distribution made up substantially of volunteers. (Which is not to dismiss their fantastic works, but rather to highlight that complaining that they’re not keeping up promptly would be a bit like complaining that Wikipedia isn’t yet fully up to date with current events!)
In both cases, I expect that development of both has been substantially delayed by people quite rightly taking a break over Christmas.
I need 565.77:
I installed Debian unstable KDE with Nvidia’s nvidia-driver 565.57.01-1 [HowTo] Install Debian unstable KDE by mmdebstrap from a live testing - Debian User Forums, patched Patch for 565.57.01 + Linux kernel 6.12
dkms remove -m nvidia -v 565.57.01 -k 6.12.6-amd64;dkms install -m nvidia -v 565.57.01 -k 6.12.6-amd64
: landing on SDDM, Plasma (Wayland), log in, black screen few seconds then relanding on SDDM.
X11 works.
Not that issue with NVIDIA-Linux-x86_64-565.77.run: * Fixed a bug that could cause KDE Plasma 6 to crash when running as a Wayland compositor.".
