_requireMinted() is in master but is not in v4.6

[oksusu12]

For contracts/token/ERC721/ERC721.sol, it seems to be that _requireMinted() function was introduced in v.4.7.
https://github.com/OpenZeppelin/openzeppelin-contracts/blob/release-v4.7/contracts/token/ERC721/ERC721.sol
has requireMinted()
but https://github.com/OpenZeppelin/openzeppelin-contracts/blob/release-v4.6/contracts/token/ERC721/ERC721.sol
does not have requireMinted().

in master branch:
https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC721/ERC721.sol
The second line says that it is last updated v.4.6.
// OpenZeppelin Contracts (last updated v4.6.0) (token/ERC721/ERC721.sol)
But it doesn't have requireMinted().

Is this expected?
I assumed that it was a minor bug in master branch. Should be
// OpenZeppelin Contracts (last updated v4.7.0) (token/ERC721/ERC721.sol)

_requireMinted() was introduced in #3438, which is part of 4.7

It was not part of 4.6 or any other version before that.

The last updated message is updated when a version is fully released. 4.7 is still a release candidate, and was not yet merged back in the master, so the last updated message was not yet updated on master.

@Amxx one of my ERC721 contracts does not have the _requireMinted() function yet does that pose a malicious risk to the contract? or this just for clarity? Thanks I'll be anticipating your response.

That is not a security concern. Don't worry
