Jest Environment JSDOM has released a new version, 26.6.2, succeeding the previous stable version 26.6.1. Both versions maintain the MIT license and are part of the Jest testing framework, residing in the packages/jest-environment-jsdom directory of the Jest repository. Examining the changes, the core dependencies on jsdom, jest-mock, jest-util, @jest/types, @types/node, @jest/environment, and @jest/fake-timers have been updated to versions 26.6.2 from 26.6.1 to ensure better compatibility.
A notable addition in 26.6.2 is the inclusion of @jest/test-utils as a dev dependency and the dependency to @types/jest and @jest/environment. These additions likely aim to improve the environment's internal testing capabilities and possibly provide better utility functions for developers extending or contributing to the JSDOM environment.

Upgrade to the newest version is recommended for the improvements to the testing environment, along with a better integration with Jest framework.
