[Batuhan Icoz](https://www.checklyhq.com/blog/author/batuhan/)

March 20, 2020 · Updated January 15, 2024

We’ve just upgraded the Puppeteer library for our browser checks from v1.19 to v2.0.0.

This release of Puppeteer is stable and includes [73 commits](https://github.com/puppeteer/puppeteer/compare/v1.19.0...v2.0.0) of new features, enhancements and bug fixes. Here are some notable changes from the Puppeteer release notes:

## Notable changes

### An updated Chromium

Chromium version is upgraded to 79.0.3942.0 (r706915) from 77.0.3844.0 (r674921).

### NodeJS v10

Browser checks now use NodeJS version 10 instead of version 8. With this upgrade, your startup/teardown scripts and browser scripts now all run on the same version.

### New API's

Along with general improvements, this Puppeteer upgrade brings these new API's you can use in your browser checks:

### Other changes

- page.screenshot now clips elements to the viewport ([#5080)](https://github.com/puppeteer/puppeteer/issues/5080)
- **Breaking change**: [page.emulateMedia(type)](https://github.com/GoogleChrome/puppeteer/blob/v2.0.0/docs/api.md#pageemulatemediatype) was deprecated and removed. You can use [page.emulateMediaType(type)](https://github.com/GoogleChrome/puppeteer/blob/v2.0.0/docs/api.md#pageemulatemediatypetype) instead. Unless you are using this API in your browser scripts, your existing checks will work without any problem. If you encounter any issues, please don't hesitate to contact us.
