Upgrading HandlebarJS to v 4.7.6 from v3.0.3

[asklimetech]

Could you please help me to understand, does upgrading Handlebarjs V3.0.3 to V4.7.6 will cause any backward compatibility issue or any other issues?
As the Project size too big, so just want to be more careful before upgrading the version.

Thanks.
