* First release of Upgradeable variant, replacing Ethereum Package variant which is now deprecated.
### Upgrading from OpenZeppelin Contracts Ethereum Package
* The dependency on `@openzeppelin/contracts-ethereum-package` should be replaced by `@openzeppelin/contracts-upgradeable`.
* All contracts, interfaces, and libraries now have an `Upgradeable` suffix, instead of the `UpgradeSafe` suffix that only contracts used to have. The only exception is the `Initializable` contract which retains its original name.
*`Address` → `AddressUpgradeable`
*`ERC20UpgradeSafe` → `ERC20Upgradeable`
* This change improves compatibility with the main OpenZeppelin Contracts package, allowing both to be used side by side.
* Solidity files are now also suffixed, to keep the Solidity convention of equal file and contract name.
