Greetings Swiftlings,

The [review](https://forums.swift.org/t/se-0546-same-file-memberwise-initializer-extensions/89120/14) of [SE-0546 Same-file memberwise initializer extensions](https://github.com/swiftlang/swift-evolution/blob/main/proposals/0546-memberwise-init-extensions.md) concluded on September 4, 2026. Feedback was generally positive. During the review period it was suggested that the same rule should apply to default `init()` initializers, and the author and LSG agreed with this suggested change, so it was incorporated. The proposal is **accepted**.

Thank you to everyone who participated in the review for helping to make Swift a better language!
