+
+# SwiftWasm 5.8.0 is now available
+
+We're happy to announce the new release of SwiftWasm tracking upstream Swift 5.8!
+
+Notable WebAssembly-specific changes in this release:
+
+- The toolchain is now available for Ubuntu 22.04 on the `x86_64` architecture. (Note that `aarch64` support is available only for macOS and Ubuntu 20.04 for now.)
+- Support for [Distributed Actors](https://github.com/apple/swift-evolution/blob/main/proposals/0336-distributed-actor-isolation.md) on WebAssembly was added.
+- The `ghcr.io/swiftwasm/swift` Docker image is now based on Ubuntu 22.04 by default for `latest` and `5.8` tags.
+
+As for changes in upstream Swift 5.8, we recommend referring [to the official
+changelog](https://github.com/apple/swift/blob/release/5.8/CHANGELOG.md#swift-58).
+
+For more information about SwiftWasm in general and for getting started, please visit [the project documentation](https://book.swiftwasm.org/).
+If you have any questions, please come and talk to us on [the SwiftWasm discussion forums](https://github.com/swiftwasm/swift/discussions)
+or [open an issue](https://github.com/swiftwasm/swift/issues/new)!
+
+## Acknowledgements
+
+We'd like to thank [our GitHub sponsors](https://github.com/sponsors/swiftwasm) and [OpenCollective
+contributors](https://opencollective.com/swiftwasm) for their support, which allowed us to continue working on SwiftWasm
+and related projects.
+
+We're committed to publishing transparent and open finances, so all expenses and transactions can be
+viewed publicly on our [OpenCollective Transactions](https://opencollective.com/swiftwasm/transactions) page.
+
+So far we've spent money on monthly CI bills that cover new `aarch64` CPU architecture and [community CI](https://ci-external.swift.org/job/oss-swift-RA-linux-ubuntu-20.04-webassembly),
+domain registration, email hosting, and development hardware for our maintainers.
+
+Many thanks to [MacStadium](https://www.macstadium.com) for giving us access to Apple Silicon hardware.
+
+Additionally, we'd like to thank everyone who contributed their work and helped us make this release
+happen. These new releases wouldn't be possible without the hard work of them and the Swift community as a whole.
+
+
+## About the last release
+
+We forgot to announce the [last release of SwiftWasm 5.7](https://github.com/swiftwasm/swift/releases/tag/swift-wasm-5.7.3-RELEASE) in this blog, so here's a quick summary of what was included in
+that release:
+
+- The Foundation and XCTest core libraries were shipped without release optimizations.
+  [Now they're built with release optimizations enabled](https://github.com/swiftwasm/swift/pull/4355), which should improve performance of SwiftWasm apps.
+- Support for [duration-based `Task.sleep`](https://github.com/apple/swift-evolution/blob/main/proposals/0329-clock-instant-duration.md) was added.
