The second iOS 18.4 Release Candidate build is rolling out to developers and public beta testers today. In conjunction with that, Apple has shared the official release notes for iOS 18.4 for the first time. The release notes cover much of what weve reported here at 9to5Mac over the last month, but with a few new tidbits. Apple has confirmed that iOS 18.4 will be released to everyone in April. With beat testing winding down, were likely looking at a release date as soon as next week. iOS 18.4 will be available to all iPhone models that run iOS 18. Apple Intelligence changes, however, are only available on a subset of those phones.
