Apple has seeded the first betas of iOS 26.3 and iPadOS 26.3 to developers for testing. The build number is 23D5089e.
This beta cycle begins just three days after the public launch of iOS 26.2. That update brought opacity controls for the Liquid Glass UI, AirDrop verification codes, and several improvements to Apple Music and Podcasts.
We are currently installing the update to see what's new. Given the timing, this likely focuses on bug fixes and stability improvements that didn't make the cut for the holiday release. However, we are keeping an eye out for early signs of the Siri overhaul rumored for the spring. We'll update this article if we find anything significant.
Developers can download the new build from the Apple Developer Center at the link below. You can also grab it over-the-air via Settings > General > Software Update by selecting the iOS 26 Developer Beta option.
