Hi,
Thank you so much for your interest in our products and for using our community.
There is no internal plan of a new release. Sorry for the inconvenient.
Auto Zephyr has 2 versions: downstream (Flexera) and upstream (github). The downstream version has the latest version of CD4 as in Apr/23. It can be found in S32K3 Reference Software package:

The upstream version has been included in the Zephyr community in Sep/23 and maintained by Zephyr community since then. Upstream Zephyr version 4.0.0 shall be published on 15/Nov/24.
Hope it helps you.
Have a nice day!
