v1.11.0 RC 1

Thanks to all the amazing contributors who participated in this release cycle! 🎉 🐶

We love seeing the community involved, so we're trying something new this time.

Instead of our monthly release, this is a release candidate. We want to encourage the community to review the code introduced, and to report and help us fix significant bugs in the release branch, should any show up. The review period will last for a week, after which we'll release v1.11.0.

You'll find the release candidate in the next tag of the npm package.

$ npm install openzeppelin-solidity@next

We know some of you have been waiting for the implementation of the now final ERC721. You will find it here, but for any serious use please wait for the review period to be over. 🙂
