I just noticed that in Messages it seems like now, in order to send a message you have to hit the blue arrow in the text field. The blue "Send" button has been replaced by return and that goes to a new line like you'd expect. Just curious, is this the same for everyone else? Hadn't seen it discussed in this thread. Not sure how much I like it. The send button was so easy to hit. On the other hand, the arrow button isn't really hard to hit, it'll just take some getting used to. Also, might help prevent accidentally sending messages mid-sentence. Definitely done that a lot in the past.
