iOS 17.4 was released last week following over a month of beta testing, and the update includes many new features and changes for the iPhone.
iOS 17.4 introduces major changes to the App Store, Safari, and Apple Pay in the EU, in response to the Digital Markets Act. Other new features include Apple Podcasts transcripts, an iMessage security upgrade, new emoji options, and more.
Below, we have provided more details about iOS 17.4's new features and changes.
App Store Changes in EU
To comply with the EU's Digital Markets Act, Apple announced major changes to the App Store, Apple Pay, Safari, and more. These changes have been implemented with iOS 17.4 for iPhone users who reside in the 27 countries that belong to the EU.
First and foremost, Apple now allows alternative app marketplaces and alternative payment options on the App Store in the EU. Other changes in the EU include a new default web browser selection screen in Safari, the ability for third-party web browsers to use web engines other than Apple's WebKit on the iPhone, the ability for third-party mobile wallet apps to access the iPhone's NFC chip for contactless payment functionality, and more.
For more details, read our recap of all of the EU changes in iOS 17.4 and Apple's overview.
Apple Podcasts Transcripts
Starting with iOS 17.4, the Apple Podcasts app now offers transcripts for podcasts, allowing listeners to read the full text of an episode, search for a specific word or phrase, and tap on the text to jump to a certain part of the episode. As an episode plays, each word is highlighted, similar to Apple Music song lyrics.
Apple says it automatically generates transcripts after a new episode is published. Transcripts are available for podcasts in English, French, German, and Spanish, and they will be added for older episodes in a podcast's catalog over time.
iMessage Security Upgrade
Apple recently announced a new post-quantum cryptographic protocol for iMessage called PQ3. Apple says this "groundbreaking" and "state-of-the-art" protocol provides "extensive defenses against even highly sophisticated quantum attacks."
iMessage already supports end-to-end encryption, but security researchers recognize that existing cryptographic protocols used by messaging apps rely on mathematical problems that could potentially be solved by future quantum computers. While these computers do not exist yet, Apple is preparing for the future with PQ3's new protections.
PQ3 will be gradually rolling out for supported iMessage conversations starting with iOS 17.4, iPadOS 17.4, macOS 14.4, and watchOS 10.4, according to Apple, and the company says it will fully replace iMessage's existing cryptography protocol within all supported conversations starting later this year. All devices in an iMessage conversation must be updated to the above-mentioned software versions or later to be eligible.

New Emoji
iOS 17.4 adds new emoji, including a broken chain, a brown mushroom, a head shaking horizontally, a head shaking vertically, a lime, and a phoenix.
Next-Generation CarPlay Apps
iOS 17.4 includes code for eight next-generation CarPlay apps:
- Auto Settings: This app will let you manage paired iPhones and adjust vehicle settings.
- Car Camera: This app will display the vehicle's rear-view camera feed.
- Charge: For electric vehicles, this app will display battery level, charging status, time remaining until the battery is fully charged, and more.
- Climate: This app will provide access to a vehicle's climate controls within CarPlay, allowing you to adjust the temperature of the A/C or heating system, fan speed, heated seats, heated steering wheel, and more.
- Closures: This app will display if any of the vehicle's doors are opened, and it might also display vehicle warning symbols.
- Media: This app will provide access to FM and AM radio station controls within CarPlay, along with other media options like SiriusXM. It is unclear if SiriusXM will offer satellite connectivity, or remain limited to internet streaming. Users will be able to select from a list of music genres, such as Top 40 and Rock.
- Tire Pressure: This app will display air pressure for each of the vehicle's tires, and provide low pressure, high pressure, and flat tire warnings.
- Trips: This app will provide a variety of driving-related data, including the vehicle's average speed, fuel efficiency or energy efficiency, the total time elapsed and distance traveled on a trip, and more.
Apple says the first vehicles with next-generation CarPlay will be released "in 2024," but the company has yet to provide a more specific timeframe. Aston Martin and Porsche previewed their next-generation CarPlay interfaces in December.
