Apple’s iOS 26.5 and iPadOS 26.5 Release Candidate 2 Nears Public Deployment

What Are Release Candidate Builds?

Release candidate (RC) builds are the final pre-release versions of software that Apple sends to developers before a public launch. They typically incorporate all planned features and fixes, with only minor last-minute adjustments if critical bugs surface. The release of a second RC—like the one we’re seeing now with iOS 26.5 and iPadOS 26.5—is often a signal that Apple is fine-tuning the update to ensure stability, but it can also indicate that the final version is just around the corner.

Second RC Build Arrives One Week After Fourth Beta

Apple has seeded a second round of release candidate builds for iOS 26.5 and iPadOS 26.5, bringing the updates a step closer to public release. This new RC build—identified by the number 23F77 on Apple’s developer portal—replaces the earlier RC build 23F75, which was released on May 4. The timing is notable: the second RC arrived exactly one week after the fourth beta cycle, suggesting that internal testing uncovered a relatively small set of issues that needed to be addressed before the green light is given for a wide rollout.

Tiny Fixes, Big Importance

Although the changelog for the second RC is likely light—focusing on minor bug squashes and performance tweaks—these adjustments are critical for ensuring a smooth experience on millions of iPhones and iPads. Release candidates are notorious for being the final builds Apple ships publicly unless major bugs force additional revisions during last-minute testing. By issuing a second RC, Apple is demonstrating its commitment to polish and reliability.

The Return of ‘Liquid Glass’ in iOS 26.5

One of the marquee features of the iOS 26 series is the Liquid Glass interface, which first appeared in earlier betas. This design language uses translucent, glass-like elements to create a sense of depth and fluidity. In iOS 26.5, Liquid Glass is being refined with smoother animations and improved responsiveness, especially on older devices. While the second RC doesn’t introduce any dramatic visual overhauls, it does contain optimizations that make the Liquid Glass effects feel more natural and less resource-intensive.

What iOS 26.5 and iPadOS 26.5 Bring to the Table

Beyond the Liquid Glass enhancements, iOS 26.5 and iPadOS 26.5 are expected to include a range of improvements:

• Security patches: Addresses vulnerabilities discovered since the last major update.
• Bug fixes: Resolves issues with Bluetooth connectivity, app crashes, and battery drain reported during the beta phase.
• Performance tweaks: Optimizations for multitasking on iPad and smoother animations across the system.
• New emoji: Adds a handful of new characters as part of the Unicode 15.1 update.

These builds are also expected to lay the groundwork for future features, such as enhanced release candidate stability for the next major iOS iteration.

Timeline to Public Release

With the second RC now in developers’ hands, the public release of iOS 26.5 and iPadOS 26.5 is likely imminent—perhaps within a week or two. Historically, Apple has released final versions shortly after seeding an RC 2 when no further critical issues are found. Users can expect the update to appear as an over-the-air (OTA) download for compatible iPhones and iPads.

Compatible Devices

iOS 26.5 will support the same devices as iOS 26, including the iPhone 15 series down to the iPhone XR. iPadOS 26.5 will run on iPad Pro models from 2018 onward, iPad Air 3rd generation and later, iPad mini 5th generation and later, and iPad 6th generation and later.

What to Watch For

As the final release approaches, developers conducting thorough tests may uncover last-minute bugs that could prompt a third RC. However, given the incremental nature of this second RC, it’s more likely that Apple will proceed directly to a public launch. Users who are eager to try the latest features can install the RC by enrolling their devices in Apple’s developer program or the public beta program, but as with any pre-release software, caution is advised.

Conclusion

The release of a second RC build for iOS 26.5 and iPadOS 26.5 brings Apple’s software update cycle one step closer to a stable public version. With build number 23F77 now on developer servers, the focus remains on polishing the Liquid Glass interface, ironing out minor bugs, and ensuring overall system reliability. Users can expect the final release to land within days, bringing a refined and secure experience to their devices.
