PQ3 is an improve to the end-to-end encryption that Apple presently makes use of for iMessage. The encryption improve goals to thwart future harvest-now-decrypt-later assaults, the place hackers will stockpile encrypted knowledge with the hopes that future quantum computer systems with sufficient pc energy can break the encryption and supply entry to the encrypted knowledge.
Safety researchers speculate that we’re nonetheless a few decade away from quantum computer systems able to such assaults, however the aim right here is to beat would-be attackers to the punch. Alongside upgraded PQC cryptography protocols, Apple has additionally carried out ongoing PQ3 rekeying, which ought to additional harden safety by issuing new keys mechanically, so even when one key’s compromised, the dialog knowledge can be secured once more by an up to date key.
For all of the nitty-gritty particulars, learn our explainer submit on quantum pc safety for iMessage.
Up to date ‘Hi there’ Display
After upgrading to iOS 17.4, customers will discover an up to date Hi there display screen that includes the profile picture linked to the person’s Apple ID.

With iOS 17.4, Apple Maps will let customers swap the specified show sort between the primary and instrument cluster screens. A map configuration button within the higher right-hand nook lets customers toggle show sort, putting navigation data on the instrument cluster show and affording extra actual property on the primary CarPlay display screen for different apps and actions.
Battery Well being updates
Apple has made a number of modifications to Battery Well being data in iOS 17.4 beta 4. For starters, Battery Well being and Charging optimization data is now decoupled, and every now seems of their respective desire panels inside Settings → Battery.
Additionally modified is a simplified battery well being standing that lets customers study their battery standing at a look. Statuses embrace ‘Regular’ however can even seemingly have ‘Service required’ if the best way the Mac handles battery well being is what Apple is pattering the iOS modifications after.

Lastly, Apple has up to date the iPhone 15 lineup’s battery lifespan. As a result of a number of elements, Apple now says that customers can count on to attain as much as 1000 battery cycles earlier than the battery degrades to 80%, double the earlier steerage. This modification applies to gadgets within the iPhone 15 lineup solely, so iPhone 14 gadgets and under will nonetheless be rated for 500 cycles.
9to5Mac’s take
iOS 17.4 is already an enormous replace because of the EU DMA modifications we’ve mentioned in depth. Nonetheless, Apple continues to be specializing in modifications that don’t straight relate to the necessary updates for customers within the European Union.
The iMessage encryption replace is especially fascinating and exhibits that Apple perceives quantum computing as an actual risk to present encryption schemes. Corporations like Sign have already began to take proactive measures, however we’ll in all probability see different firms introduce comparable encryption updates now that Apple has made this transfer.
