Recommended Repository and image for ODROID-C4/HC4

Hello,
I am using HA on ODROID HC4 (same ARM CPU as the ODROID-C4) via Docker container on OMV. I have installed it from the default repository (homeassistant/odroid-c4-homeassistant:stable) and have been successfully updating it since. But now I have not received any updates for the last few months so I am stuck on HA version 2023.6.3.

I have reviewed the latest installation instructions for Odroid] and noticed that now it is recommended to use ghcr io repository and the standard image (ghcrDOTio/home-assistant/home-assistant:stable). I have also found that the updated C4 platform image is also available in the ghcr repository (ghcrDOTio/home-assistant/odroid-c4-homeassistant:stable).

Questions:

  1. Is odroid-c4 image on dockerhub repository still being maintained (homeassistant/odroid-c4-homeassistant:stable)
  2. If not, should I use the standard image, or C4 image from ghcr
  3. Can I upgrade from 2023.6.3 directly to the latest version? May this cause any issues/incompatibilities?

Thank you!
