This is a great defensive plugin. The ability to easily browse changelogs is a huge improvement to WP Rollback.

WordPress has gone update crazy - update core to the latest beta, update WooCommerce to a beta 3, face security issues (WordPress 4.7.x through to 4.7.4), incompatibility, endless software renewal costs, troubleshooting. In the end, you have to hire professionals (us) to clear up the mess. Latest fun is in 4.8 where the flexible text widget was force replaced with a WYSIWYG widget which broke a huge number of existing text widgets and hence sites.

How this user pain is supposed to result in higher WordPress satisfaction ratings and market share is a mystery to me.

Our own defensive approach has been to give site owners back control of updates. Update what you want, when you want, while automatically applying security updates (which go back to 3.7.x still). With control over updates, we've reduced our clients' maintenance burden by a factor of four - they are delighted to spend their budgets on real site and business improvements.
