iOS 26.4 available now: All updates, security improvements to know

Apple released iOS 26.4 on Tuesday, bringing a wide range of new features, quality-of-life improvements, and numerous security patches.

The release touches nearly every corner of the operating system — from the Music and Podcasts apps to the kernel — and includes changes that will be noticeable to casual users and security-conscious ones alike. The update is available for iPhone 11 and later and iPad models going back to the iPad Air 3rd generation, iPad Pro 11-inch 1st generation, iPad 8th generation, and iPad mini 5th generation.

Here's what to know.

Apple Music gets smarter

Music lovers have a few reasons to update. A new Playlist Playground feature lets Apple Music generate a 25-song playlist from a text prompt, with the option to refine the results with follow-up prompts. The feature is currently available only in the US.

Apple Music has also added a "Concerts Near You" section, powered by a Ticketmaster partnership, that surfaces local show info directly in the app. And song recognition — think Shazam-style identification — now works offline, queuing up results to deliver once you're back on a network.

Additionally, the Podcasts app now supports video podcasts, bringing it in line with platforms like YouTube and Spotify that have offered the format for some time.

Security and privacy improvements

One of the more meaningful changes in iOS 26.4 is that Stolen Device Protection is now enabled by default, rather than requiring users to opt in. The feature, which adds biometric requirements for sensitive actions when your iPhone is away from familiar locations, is now on by default for everyone.

On the security patch front, Apple addressed dozens of vulnerabilities across the OS. Notable fixes include a Siri flaw that could have allowed someone with physical access to a locked device to view sensitive information, a Keychain vulnerability that could have given a local attacker access to stored credentials, and several WebKit issues that could have enabled cross-site scripting attacks, sandbox bypasses, or Content Security Policy circumvention when visiting malicious websites.

Multiple kernel-level vulnerabilities were also patched, including issues that could have allowed apps to corrupt kernel memory or leak sensitive kernel state.

New features across the system

iOS 26.4 brings a handful of additions scattered across the operating system. The Messages app has new animations, and a new ambient music widget has been added for the home and lock screens. Freeform now includes a Creator Studio for subscribers, offering access to high-quality graphics, photos, and illustrations not available to free users.

The Reminders app now includes an Urgent section for high-priority tasks. In the Health app, a new average bedtime metric helps users better understand how their sleep schedule affects overall sleep quality, and the Vitals section now shows blood oxygen levels on its line graph overview.

For accessibility, a new "Reduce Bright Effects" option minimizes bright flashes from interface elements, and the existing Reduce Motion setting now more reliably damps down liquid glass animations.

Camera, CarPlay, and more

The Camera app gains Audio Zoom, which focuses recorded audio on the subject when you zoom in — the feature can be turned off in settings. In CarPlay, AI assistants, including Claude, Gemini, and ChatGPT, are now accessible for hands-free questions, though none require a wake word to activate.

Rounding out the update: a new Set Charge Limit action has been added to Shortcuts, and Apple says it has addressed a longstanding keyboard bug that caused characters to be dropped during fast typing.
