Apple has released the third beta of iOS 26.3 for developers and public beta testers. The third beta update was initially expected last week, but Apple skipped all update releases during that period. Today, however, the company has rolled out multiple updates, including iOS 26.3 Beta 3.
In addition to iOS 26.3 Beta 3, Apple has also released iOS 26.2.1, iPadOS 26.2.1, watchOS 26.2.1, iOS 18.7.4, iOS 16.7.13, iOS 15.8.6, iOS 12.5.8, iPadOS 26.3 Beta 3, watchOS 26.3 Beta 3, tvOS 26.3 Beta 3, macOS Tahoe 26.3 Beta 3, and visionOS 26.3 Beta 3.

The iOS 26.3 Beta 3 comes with build number 23D5114d, while the iOS 26.2.1 is available with build 23C71. With each new beta release, we are getting closer to the public release of iOS 26.3. Therefore, this and upcoming beta builds will not feature major changes but rather a few improvements and bug fixes.
The iOS 26.2.1 is also a minor update that includes security improvements and bug fixes. Although it is a small update, it is still important due to its security fixes.
If you are using iOS 26.3 Beta, you can update your device to the latest iOS 26.3 Beta 3 by going to Settings > General > Software Update. If you are using a public build like iOS 26.2, you can update to the iOS 26.2.1 update.
It is recommended that you take a backup of your data before installing an update just in case. If you are wondering when iOS 26.3 will be released to the public, it is expected to be released in the second or third week of February.
