const docMigration = `ERC20, ERC721, and ERC1155
These breaking changes will require modifications to ERC20, ERC721, and ERC1155 contracts, since the _afterTokenTransfer and _beforeTokenTransfer functions were removed. 
Thus, any customization made through those hooks should now be done overriding the new _update function instead.
Minting and burning are implemented by _update and customizations should be done by overriding this function as well. _transfer, _mint and _burn are no longer virtual (meaning they are not overridable) to guard against possible inconsistencies.

For example, a contract using ERC20's _beforeTokenTransfer hook would have to be changed in the following way.
More about ERC721
In the case of ERC721, the _update function does not include a from parameter, as the sender is implicitly the previous owner of the tokenId. The address of this previous owner is returned by the _update function, so it can be used for a posteriori checks. In addition to to and tokenId, a third parameter (auth) is present in this function. This parameter enabled an optional check that the caller/spender is approved to do the transfer. This check cannot be performed after the transfer (because the transfer resets the approval), and doing it before _update would require a duplicate call to _ownerOf.

In this logic of removing hidden SLOADs, the _isApprovedOrOwner function was removed in favor of a new _isAuthorized function. Overrides that used to target the _isApprovedOrOwner should now be performed on the _isAuthorized function. Calls to _isApprovedOrOwner that preceded a call to _transfer, _burn or _approve should be removed in favor of using the auth argument in _update and _approve. This is showcased in ERC721Burnable.burn and in ERC721Wrapper.withdrawTo.

The _exists function was removed. Calls to this function can be replaced by _ownerOf(tokenId) != address(0).`
