This version drops support for IE8. events no longer includes polyfills
for ES5 features. If you need to support older environments, use an ES5 shim
like es5-shim. Both the shim and sham
versions of es5-shim are necessary.

• Update to events code from Node.js 10.x
  • (semver major) Adds off() method
• Port more tests from Node.js

Another for v17!
