Dependencies now ships an @DependencyEntry macro for registering dependencies with far less boilerplate. It was tricky to design because the library must model live, preview, and test environments, but the final API manages to stay concise without giving up that power.

The swift-dependencies library now ships a new `@DependencyEntry` macro that dramatically reduces boilerplate when registering dependencies. Inspired by SwiftUI's `@Entry` macro, it handles the library's three-environment model (live, preview, test) through a concise API: the property initializer becomes the `testValue`, while `liveValue:` and `previewValue:` can be passed as macro arguments. Omitting `liveValue` keeps the dependency conforming only to `TestDependencyKey`, preserving the ability to separate interface from live implementation for modular codebases. Available in Dependencies version 1.13 via the `DependenciesMacros` module.
