Hi there, in cosmwasm. v0.14.0 struct HumanAddr and other definitions such as HandleResponse, Initresponse and MigrateResponse are depreciated does that means that all the cosmwasm tutorials on [GitHub - enigmampc/SecretNetwork: 𝕊 The Secret Network](https://github.com/enigmampc/SecretNetwork) are also outdated?

As replied in Discord:  
Secret Network uses cosmwasm 0.10, So only cosmwasm tutorials up to 0.11 or 0.12 are precisely applicable. Now, while after that the changes started becoming more noticeable, almost all of them are surface-level changes. if you get the gist of 0.14, you’ll be able to figure out how to use 0.10 as well.
