Hello,
What Is any differences between the two versions?
Difference is state in release notes:

there is no zip/rar download pack, just only exe?
I see the download packages in NXP software account only for EB tresos (*.exe) files.

So the SDK will be available in S32DS extension and updates directly.
But I see it supports only v 3.4 and not v3.5 of S32DS.

Best regards,
Peter
