[wix-users] Backward compatibility level of latest 3.X version of WIX with 3.4/3.5 version?

[Rajeev Bansal (WSSC)]

Hi,

What is the backward compatibility level of latest 3.X version of WIX with 3.4/3.5 version?
We are at the 3.5 version of WIX and wants to upgrade to latest 3.X version, so want to know if we have some breaking changes on the way and do we claim latest WIX 3.X versions are fully backward compatible?

Thanks,
Rajeev
