Apple's busy today -- on top of finally releasing Photos, it's rolling out the long-expected iOS 8.3 update. It's not as huge as 8.2 was, but you'll likely appreciate it if you're a tech-savvy driver. The upgrade brings wireless CarPlay in supporting vehicles, so you don't have to plug in your iPhone just to get directions or music on your car's center display. You'll also find more diverse emoji (as in OS X), the option to download free apps without a password and a much easier way of signing into Google accounts when you use two-factor authentication. There's a whole bunch of app performance and interface fixes on top of this, so you'll definitely want to grab the 8.3 patch when you get the chance.
