Use current python-picamera2 with Arudcam B0272

I’m very confused with installation for B0272 as described here.

From the logs while installing I see that it downgrades python3-picamera2 to version 0.3.12-2
Is this intended?
How can we use current versions to profit from performance enhancements?
Is it compatible?
How often does custom arducam libcamera packages etc. get updated?
How do we know? Is there a repository to follow?

Hi,

If you find that picamera2 is downgraded, you can reinstall it directly using the command sudo apt install python3-picamera2.

Arducam custom libcamera update follows when the Raspberry Pi updates libcamera.
This is the repository: GitHub - ArduCAM/libcamera
