Hello Swift Community,

The [review](https://forums.swift.org/t/se-0485-outputspan-delegate-initialization-of-contiguous-memory/80032) of [SE-0485 "OutputSpan: delegate initialization of contiguous memory"](https://github.com/swiftlang/swift-evolution/blob/main/proposals/0485-outputspan.md) concluded on June 3, 2025. The proposal is _accepted_ with a few modifications:

- Add the immortal public `init()` initializer to Span and MutableSpan as well, as mentioned in the review thread.

- Fix incorrectly-named `available` property to `freeCapacity`, as discussed in the review thread.

- Defer the bulk-appending operations (e.g., `append` overloads for iterators, sequences, spans, etc.) so they can be handled more comprehensively in a separate proposal.
