chaijs/chai 3.0.0

3.0.0 / 2015-06-04

on GitHub

This release contains some small breaking changes. Most people are unlikely to
notice them - but here are the breaking changes:

• Switched from "Component" builds to "Browserify" builds for Browsers. If
  you're using RequireJS with Chai, you might notice a change (chai used to
  be a global, now it won't be - instead you'll have to require it).
• .has.property('foo', undefined) will now specifically test to make sure
  that the value 'foo' is actually undefined - before it simply tested that
  the key existed (but could have a value).
• .to.be.a('type') has changed to support more types, including ES6 types
  such as 'promise', 'symbol', 'float32array' etc, this also means using
  ES6's Symbol.toStringTag affects the behaviour .to.be.a(). In addition to
  this, Errors have the type of 'error'.
• assert.ifError() now follows Node's assert.ifError() behaviour - in other
  words, if the first argument is truthy, it'll throw it.
• ReleaseNotes.md is no longer maintained, see the Github Releases Page instead.
• History.md is no longer maintained, see the Github Commit Log instead.
