Release Notes

Starcounter-Jack/JSON-Patch

### [`v2.2.1`](https://togithub.com/Starcounter-Jack/JSON-Patch/releases/v2.2.1) [Compare Source](https://togithub.com/Starcounter-Jack/JSON-Patch/compare/v2.2.0...v2.2.1) This patch release fixes a regression introduced in 2.2.0, namely: the default import using ES6 with Webpack/Babel stopped working ([#​233](https://togithub.com/Starcounter-Jack/JSON-Patch/issues/233)). This version fixes the problem by adding an explicit default import. ### [`v2.2.0`](https://togithub.com/Starcounter-Jack/JSON-Patch/releases/v2.2.0) [Compare Source](https://togithub.com/Starcounter-Jack/JSON-Patch/compare/v2.1.0...v2.2.0) New feature: - Ability to generate test operations for original values in the first object, also known as "invertible" operations. Search fro the word `invertible` in `README.md` for details about usage (PR [#​228](https://togithub.com/Starcounter-Jack/JSON-Patch/issues/228), PR [#​226](https://togithub.com/Starcounter-Jack/JSON-Patch/issues/226)). Code quality: - Replace `deep-equal` with `fast-deep-equal` (PR [#​227](https://togithub.com/Starcounter-Jack/JSON-Patch/issues/227)) - Remove traces for support for legacy browsers which were broken since [v2.0.7](https://togithub.com/Starcounter-Jack/JSON-Patch/releases/tag/v2.0.7) (PR [#​229](https://togithub.com/Starcounter-Jack/JSON-Patch/issues/229)) - Fix testing framework
