This document contains a list of _breaking changes_ for Pinafore. For a full changelog, see [GitHub releases](https://github.com/nolanlawson/pinafore/releases).
## 2.0.0
For self-hosters, the new minimum Node.js versions are v12.20+, v14.14+, or v16.0+ [due to native ES Modules](https://github.com/nolanlawson/pinafore/pull/2064).
Please check your Node version using `node --version` and update as necessary.
This version [switches Pinafore from npm to yarn](https://github.com/nolanlawson/pinafore/pull/927). Those who self-host Pinafore will need to make the following changes:
1. [Install yarn](https://yarnpkg.com/en/docs/install) if you haven't already.
2. Instead of `npm install`, run `yarn --pure-lockfile`.
This change fixes [a functional bug in Webpack](https://github.com/nolanlawson/pinafore/pull/926). If you use npm instead of yarn, Pinafore may not build correctly.
### Notes:
- Using `yarn start` instead of `npm start` should not make a difference.
- Those using Docker shouldn't need to change anything.
