Token transfer

After the hard fork, I cannot use my old wallet to transfer stx. I wanna konw how many changes are applied to the stx transfering process in the hard fork.
I am a developer and the wallet program is coded by myself。
I find nothing technical about the hard fork.
I need help

Nothing changed regarding token transfers. However, I have noticed in my node’s log that a few token transfers are being rejected by the network because the consensus hash is invalid. If this was you, can you make sure that you’re getting a consensus hash from a version 21.0.0.x node?
