### Release Notes

<details>
<summary>yarnpkg/yarn</summary>

### [`v1.22.18`](https://togithub.com/yarnpkg/yarn/releases/v1.22.18)

[Compare Source](https://togithub.com/yarnpkg/yarn/compare/v1.22.17...v1.22.18)

Node 17.7.0 had a regression in `url.resolve` which broke Yarn, causing network errors. This release fixes that, although the regression also got fixed on the Node side starting from 17.7.1, so as long as you keep your Node up-to-date it'll be fine.
