Another iOS 27 beta has arrived, and here are all the new features and upgrades

Following the launch of the iOS 27 public beta early last week, the fourth iteration of the developer beta is now rolling out as well. Since the developer beta is slightly ahead of the public option, this means there are a bunch of new features coming to those of you that signed up.

This update isn't particularly extravagant — offering a few small upgrades and fixes rather than a bunch of new features. However, the changes are important quality of life updates, which should improve your overall iOS 27 experience — either as a beta tester or once the official version lands later this year.

Here's what's changed in iOS 27 beta 4.

Changes have come to Siri, with the most noticeable update being a new "splash screen" that appears when you summon the AI from either the Dynamic Island or your home screen. This features a little more information about the "All-New Siri" and gives a brief explainer for those users who may not be familiar with what the changes to Siri mean.

The recent apps menu in the pull-down menu has also been fixed with this new update, with the app options no longer appearing grayed out.

Siri's Expressive Voice feature has been drip feeding us updates over the course of multiple beta updates. Beta 3 added the ability to change the pace and expressiveness for two distinct voices. iOS 27 beta 4 adds new voices and an array of new English-language accents that you can choose from. However, the customization options are still limited to those original two American accents for the time being.

Siri's settings now include a feature to adjust the length of previews in the Siri app too. This lets you pick anywhere between zero lines of preview and five.

The Control Center now supports the AirPods Pro adaptive mode slider, which was introduced in iOS 27 beta 3. This means you can alter the level of ANC and transparency on your AirPods Pro 2, Pro 3 or AirPods 4 without necessarily having to go into the AirPods app first.

Apple TV app now includes a toggle that will set Apple TV to automatically download upcoming episodes of your favorite streaming shows. So long as the show is in your "Continue Watching" list, Apple TV will automatically download the next two episodes, and automatically delete old ones once you've finished watching.

Simply head to Settings > Apps > TV > Automatic Downloads. It's a quick process, and means it should be a lot harder to find yourself caught out with no new episodes to watch offline.

Other smaller inclusions include a new "Zoom Photos to Fill" toggle in Apple Photos, which automatically fits your photos to match your screen's aspect ratio. The camera app now has an option for ProRes log Format if ProRes is switched on, while Wi-Fi settings give you the choice to turn off Connectivity Assist for individual Wi-Fi networks.

Sadly Apple has also removed the wallpaper preview in the Notification Center, which lets you see a cutout of your wallpaper's subject as you're swiping down. It's unclear why, but I'd guess that it was probably a bug that wasn't supposed to be there.
