That's not entirely true. You can now find your history and remove the logs of your viewing. They try to force you manually to click on a lot to remove everything but if you do it will remove your viewing history and revert to showing you starting at the beginning of episodes. I confirmed this on my account.
If you have any semblance of experience with web-programming instead of clicking you can run a jQuery function within the browser console. For instance, in Chrome, right click on anything then click on the "Inspect Element" option. It doesn't matter where on the page you do this. Just make sure your on the netflix page with your history. In the console type jQuery('.deleteBtn').click(); and click enter. This command simulates mouseclicks on all your checkboxes to removing everything in your history at once without the annoyance of having to manually scroll down and click on everything. The rows in the table will look like they're updating. If you wait it'll look like the page is hanging but you don't need to let the page reload. After you follow the steps, give the page about 2-3 seconds then refresh the page-the previously displayed history records should be gone. Rinse and repeat until all your viewing history is gone.
Note if you want to only do this for one particular series, don't use the above command. Netflix has a way to remove your history for a particular series in two clicks. Click once to remove an episode, then it gives an option to remove history for an entire series.
