"Drupal 8.2.0, the next planned minor release of Drupal 8, is scheduled for Wednesday, October 5, 2016. Minor releases include new features, usability improvements, and backwards-compatible API improvements."
"As part of 8.1.x we introduced a way to test javascript code in a end-to-end testing way, this means, the entire Drupal site, (exactly like in WebTestCase / BrowserTestBase) is set up."
