+## [1.8.0] - 2026-05-25
+
+### Additions
+
+- `NameSpecification` and its elements now conform to `ExpressibleByStringLiteral`, allowing simplified option and flag name declarations. For example, `[.customLong("hex-output"), .customShort("x")]` can now be written as `"--hex-output -x"`. ([#745])
+- New `@Option` initializers accept a `defaultAsFlag:` parameter, creating options that work both as a bare flag (`--format`) and as an option with a value (`--format json`). ([#830])
+- Custom completion closures for `AsyncParsableCommand` types now support `async`/`await`. ([#855])
+
+### Changes
+
+- The minimum Swift version for `swift-argument-parser` has been updated to Swift 6. Users of older Swift versions can continue using version 1.7.1 of the library. ([#882])
+
+### Fixes
+
+- Command aliases now appear in generated man-pages for both single-page and multi-page output. ([#891])
+- Declaring `@Flag var x: Bool?` without an `inversion:` parameter now produces a useful diagnostic message. ([#892])
+
+The 1.8.0 release includes contributions from [bkhouri], [natecook1000], [nkimon00], [rauhul], and [rgoldberg]. Thank you!
