Is Asus Zenfone 8 still maintained - no updates for 5 months

Thank you for the feedback. This will be my first manual update so please confirm two points:

  1. I can go straight from version 1.19 (Android 12) to 2.1 (Android 13)? Skipping the 3 versions in between and upgrading to Android 13.
  2. this post ([HOWTO] Update /e/) is still how I should update?
