## Unreleased
* `ERC20Votes`: add a new extension of the `ERC20` token with support for voting snapshots and delegation. This extension is compatible with Compound's `Comp` token interface. ([#2632](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/2632))
* `ERC20Votes`: add a new extension of the `ERC20` token with support for voting snapshots and delegation. ([#2632](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/2632))
* `ERC20VotesComp`: Variant of `ERC20Votes` that is compatible with Compound's `Comp` token interface but restricts supply to `uint96`. ([#2706](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/2706))
* Enumerables: Improve gas cost of removal in `EnumerableSet` and `EnumerableMap`.
* Enumerables: Improve gas cost of lookup in `EnumerableSet` and `EnumerableMap`.
* `Counter`: add a reset method. ([#2678](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/2678))
* Tokens: Wrap definitely safe subtractions in `unchecked` blocks.
* Tokens: Wrap definitely safe subtractions in `unchecked` blocks.
* `Math`: Add a `ceilDiv` method for performing ceiling division.
* `ERC1155Supply`: add a new `ERC1155` extension that keeps track of the totalSupply of each tokenId. ([#2593](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/2593))
### Breaking Changes
* `ERC20FlashMint` is no longer a Draft ERC. ([#2673](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/2673)))
**How to update:** Change your import paths by removing the `draft-` prefix from `@openzeppelin/contracts/token/ERC20/extensions/draft-ERC20FlashMint.sol`.

/**
* @dev Extension of ERC20 to support Compound's voting and delegation. This version exactly matches Compound's
* interface, with the drawback of only supporting supply up to (2^96^ - 1).
*
* NOTE: You should use this contract if you need exact compatibility with COMP (for example in order to use your token
* with Governor Alpha or Bravo) and if you are sure the supply cap of 2^96^ is enough for you. Otherwise, use the
* {ERC20Votes} variant of this module.
*
* This extensions keeps a history (checkpoints) of each account's vote power. Vote power can be delegated either
* by calling the {delegate} function directly, or by providing a signature to be used with {delegateBySig}. Voting
* power can be queried through the public accessors {getCurrentVotes} and {getPriorVotes}.
*
* By default, token balance does not account for voting power. This makes transfers cheaper. The downside is that it
* requires users to delegate to themselves in order to activate checkpoints and have their voting power tracked.
* Enabling self-delegation can easily be done by overriding the {delegates} function. Keep in mind however that this
* will significantly increase the base gas cost of transfers.
*
* _Available since v4.2._
