new SDK version (4.1.7) and new firmware, will it cause problem?

Good day.

I would like to ask some technical information about the new SDK version (4.1.7).

I have applications written in CIQ that work without issue. I run into problems by switching the SDK to a new version, to avoid this I turned off the check like this:

project.typecheck = 0

The question is, now I'm using the new SDK (4.1.7) and everything works as it should, but what if Garmin releases a different firmware (CIQ 5), does aplkication stop working for me, or does it

depend on the minSDK"" parameter in the manifests. xml file?

Thanks for the replies and advice.
