@mathiasbynens mathiasbynens released this Apr 16, 2020

Big changes

  • Chromium 81.0.4044.0 (r737027)
  • Puppeteer can now fetch a Firefox Nightly binary for you via PUPPETEER_PRODUCT=firefox npm install. Also, there’s now an example showing how to launch Firefox with Puppeteer.
  • File uploads are generally more reliable (#5363) and elementHandle.uploadFile(...filePaths) now triggers a change event, matching the old behavior in Puppeteer v1.20.0. (#5389)
  • Node.js v8.x.x is no longer supported. (#5136)

Behind the scenes

  • Puppeteer is migrating to TypeScript. Although this doesn't affect the way developers can consume Puppeteer, it improves the quality of the Puppeteer type definitions which can be used by modern editors.
  • Our custom test runner framework has been removed in favor of Mocha, reducing maintenance overhead.
  • Our CI setup and the way we deal with test flakiness is being reworked in order to increase our confidence of landing PRs without breaking anything.
