Podman 5.1 dependency on yocto/linux versions

[msom-apex]

Hi Podman team,
It was overwhelming to see such a huge information about developments and bug fixes since 4.1.2
I would like to explore the latest stable 5.1.1 but am concerned about any changes that needs to be made wrt time and dependencies.

On a high level, here are the concernes:

Linux version : Do any component in 5.1.1 need a specific or higher linux version than arm 4.14?
Yocto version : Can we still work with thud ranch of yocto? do we need a different one? details on the dependency if yes
Libraries: What are the libraries required for the latest podman?
Database : Is a database compulsory to get on with 5.1.1? is yes, what is the minimum that can be adopted? space and other dependencies of the database
Communication modification: OCI instead of HTTP: can we still use older method as in 4.2.1 ? if no, what are the dependencies for this?
