Apple software engineers are testing iOS 26.5.1, according to the Woozad visitor logs, which have been a reliable indicator of upcoming iOS releases.
iOS 26.5.1 will almost certainly be a minor update fixing bugs and/or security vulnerabilities, and it will likely be released by the end of next week.
The logs show that Apple has also ramped up testing of iOS 26.6, with an early beta version of this update likely to be released at some point in June. iOS 26.6 will likely be a minor update as well. Last year, Apple released the first beta of iOS 18.6 to developers on Monday, June 16, three days after WWDC 2025 ended.
Apple is turning its attention to iOS 27, which is expected to be revealed during the WWDC 2026 keynote on Monday, June 8 at 10 a.m. PT.
