1.1.0

What's Changed

• Added: An overload of Reducer.onChange(of:) that takes a configurable removeDuplicates closure for the equality check (thanks @ohitsdaniel, #2338).
• Added: Effect.debounce and Effect.throttle, for debouncing and throttling effects on a scheduler (#2372, #2368). This functionality existed in past releases but was removed from 1.0 alongside other deprecated Combine code. Because there is no modern replacement for Effect.throttle we have brought this functionality back to 1.1.
• Fixed: XCTest failures emitted when test stores initialize state (e.g. if Reducer.State.init accesses a dependency that hasn't been overridden) are now shown in the test that creates the store rather than hidden in application code (#2352).
• Fixed: Suppressed a warning that previously emitted when instantiating a test store state with .init() instead of Feature.State() (#2347).
• Fixed: Child features presented by grandparent features are now properly dismissed when the child calls @Dependency(\.dismiss) (#2373).
• Infrastructure: Documentation updates and fixes (#2336; thanks @jayrhynas, #2342; thanks @atimca, #2350; #2353; thanks @hmhv, #2355; thanks @Ryu0118, #2358, #2367; thanks @yimajo, #2357; thanks @ValseLee, #2369, #2370).

0.55.1

What's Changed

• Fixed: BindingViewStore's dynamic member lookup has been weakened to support let properties (#2243).
• Fixed: A regression introduced in 0.55.0 caused tests equating BindingAction to fail has been fixed (thanks @bharath2020, #2248).

• Fixed: WithViewStore initializers introduced in 0.55.0 were ambiguous when working with bindable state but no bindable view state. This has been fixed (#2278).
• Fixed: Some changes to view state containing BindingViewState that SwiftUI failed to observe will now correctly be observed (#2255).
• Infrastructure: Documentation fixes (thanks @yimajo, #2242; @jessetipton, #2256, #2261, #2267; #2280) and updates (thanks @mrtnlst, #2252).

0.54.1

What's Changed

• Fixed: A regression introduced in 0.54.0 prevented some Composable Architecture projects from building in release due to a Swift compiler bug. We have removed some @inlineable attributes to work around this bug (#2201).
