There's a new server browser! If you click on multiplayer you'll get access to the server browser, which in addition to showing local network games can now show online games as well by clicking the Refresh button. To add your game to the list, click on Create Game in the bottom right. You'll then have the option to name your server, set max players, and choose whether or not to have it publicly listed on the server browser. If you do, your game will be shown on the server browser and anyone will be able to join.

There's also been a lot of memory improvements. Overall the RAM usage should be less than half of what it was, and those of you with limited RAM should experience fewer crashes.
