The new polls feature allow users to create their own online polls in their Twitter account. The Personalization section, at least for the moment, includes a way to turn video autoplays on or off for posts, except for the ones in the Moments section.
In addition, the exact time and date is now available to see for individual Twitter posts. If you notice anything else that's new or cool in this update, feel free to let us know in the comments:
Thanks to Cy for the tip!
