Tonight I was able to create a dynamic updater for Oxwall.
I Created a Plugin that combines OxBackup into one page for OxUpdater and included Symfony, Git and GitHub client API libraries.
With those libraries, I was able to create an admin section that pulls the latest Smarty Release Versions dynamically along with their download links.
Throwing those into a SelectBox dynamically allows future releases to show up automatically without needing to update the actual plugin.
The only plugin updates that will need to be included for these Library Updates in the future are to the filters to remove unstable versions if a future version doesn't work properly.
It actually pulled so many versions that I had to filter out much older versions, but you can see the actual changes immediately...
No More Deprecation Notice and Updated Latest Version Dynamically!
Core Updates will be the same, dynamically pulling the latest GitHub version...
