In the new update, True Neverclick has been removed. Also, Uncanny Clicker has been moved from Shadow to Regular achievement.
3 new upgrades have also been introduced: Snickerdoodles, Stroopwafels, and Macaroons; all of which costing 100 trillion (minus 1) cookies, and increasing your cookie income by 15% each! They require you to hit 1 trillion (minus 1) cookies to unlock. In addition, Quintillion Fingers increases your mouse and cursor cookie amounts by 100 instead of 50, making the upgrade twice as efficient! Also, another golden cookie upgrade (Get Lucky) has been added, costing 77.777... trillion cookies, which doubles the length of golden cookie effects. Lastly, another new upgrade (Sacrificial Rolling Pins) has been introduced, allowing your Elder Pledges to last twice as long. It costs 28.888... trillion cookies, and is only available after pledging 10 times to the elders.
