 - Defender: Fix handling of license types for block explorer verification, support `licenseType` and `skipLicenseType` options. ([#1013](https://github.com/OpenZeppelin/openzeppelin-upgrades/pull/1013))
 
 ### Breaking changes
+
 - When deploying through Defender, if your contract does not have an SPDX license identifier, the verified source code on Etherscan will no longer show any license type.
   - If you want the license type to appear as "None", either set your contract to have `// SPDX-License-Identifier: UNLICENSED` according to [Solidity docs](https://docs.soliditylang.org/en/latest/layout-of-source-files.html#spdx-license-identifier), or set the `licenseType` option to `"None"`.

 ### Breaking changes

 This new major version requires `ethers` v6 and `@nomicfoundation/hardhat-ethers` v3 as peer dependencies.  
 For Etherscan verification, it also requires `@nomicfoundation/hardhat-verify`.
 
 ### How to update from a previous version

 Update your existing project according to [Hardhat Toolbox v3's release notes](https://github.com/NomicFoundation/hardhat/releases/tag/%40nomicfoundation%2Fhardhat-toolbox%403.0.0).
