Migration to 13.0.0

This guide describes all breaking changes introduced with v13.0.0.

Wallet

onSign, onMessageSign callbacks were removed on the wallet side

Check allowance to sign on the account side instead, using aeppOrigin, aeppRpcClientId options.

All wallet provided nodes have the same name

Specified in name option of connectToWallet.

Select option removed from connectToWallet

If you are using connectNode then the current node would always be the same as wallet provides.
