cloudflare/miniflare v2.7.0

on GitHub

⚠️ Miniflare's minimum supported Node.js version is now 16.13.0. This was the first LTS release of Node.js 16.

We recommend you use the latest Node.js version if possible, as Cloudflare Workers use a very up-to-date version of V8. Consider using a Node.js version manager such as https://volta.sh/ or https://github.com/nvm-sh/nvm.
