The biggest addition of this release is support the .property assertion. Huge thanks to @scottnonnenberg for this!

Other notable additions include official support for Node.js v5.x (v6.x should be supported just fine, but CI tools are not building against it yet) and minor documentation improvements and additions.

v1.5.4

See the full changelog

This release brings some minor documentation improvements and dependency upgrades, as well as a nice fix by @jakelazaroff:

• Document how to integrate chai-immutable with chai-as-promised (PR #38)
• Update minor and patch versions of non-essential devDependencies
• Add Chai's Code of Conduct (PR #42)
• Use Iterable.isIterable for Immutable check to fix false results when using multiple copies of Immutable (PR #36 by @jakelazaroff)

v1.5.3

See the full changelog

This releases adds some niceness to failing tests:

• Clean up the output messages on failures to a human-readable format on equal, include and keys assertions (issue #7)
• Make sure the diff is shown when an assertion using equal is failing

Additionally, it ensures future compatibility with the new documentation system for Chai plugins (issue #34 on chai-docs).
