Hi all,

The [focused re-review](https://forums.swift.org/t/focused-re-review-se-0461-run-nonisolated-async-functions-on-the-callers-actor-by-default/78921) of [SE-0461: Run nonisolated async functions on the caller's actor by default](https://github.com/swiftlang/swift-evolution/blob/main/proposals/0461-async-function-isolation.md) concluded on April 4, 2025. The language steering group has decided to accept the proposal with the [modifications](https://forums.swift.org/t/accepted-with-modifications-and-focused-re-review-se-0461-run-nonisolated-async-functions-on-the-callers-actor-by-default/78920) detailed after the first review and a further modification.

Feedback was light but relatively positive on the proposed explicit spelling for the future default behavior of `nonisolated` async functions that run on the caller's actor—namely, `nonisolated(nonsending)`. The steering group agreed with the suggestion put forward during review and accepted by proposal authors that `@concurrent` specifically can imply `nonisolated`, and the proposal will be modified so that writing `nonisolated` is optional in conjunction with `@concurrent`.

Thank you, as always, to all participants in this review process for helping to make Swift a better language.
