Originally, our constraint was 160 (limit of a text) minus username. But we noticed @biz got 1 more than @jack. For fairness, we chose 140. Now texts are unlimited. Also, we realize that 140 isn't fair—there are differences between languages. We're testing the limits. Hello 280!— Biz Stone (@biz) September 26, 2017

It appears that everyone has the 280 character count now. Too bad... I appreciated the 140 limit, because it forced you to distill your thoughts and mercilessly edit your posts!
In addition to the longer character count, they also removed the character counter, and replaced it with a stupid circle that fills as you type.
Everyone hates it.
