New:

  • flex(double) modifier for layouts which acts as a weight along the main axis.
  • Allow reserving widget, modifier, property, and children tags in the schema. This can be used to document old items which no longer exist and prevent their values from accidentally being reused.
  • Add dangerZone { } DSL to the redwood { } Gradle extension which allows enabling Compose reports and metrics. Currently these features break build caching as Compose forces the use of absolute paths in the Kotlin compiler arguments when in use (hence why they're marked as dangerous).
  • BackHandler composable provides a callback for handling hardware back affordances (currently only on Android).
  • Expose frameClock on StandardAppLifecycle to allow monitoring host frames.
  • CodeListener.onUncaughtException notifies of any uncaught exceptions which occur in Treehouse guest code.
  • Preview: Add Box widget which stacks children on top of each other. This is currently only implemented for Android views and iOS UIKit.
  • Support rememberSaveable in plain Redwood compositions.
  • Programmatic scrolls on LazyListState can now set animated=true for an animated scroll.
  • Add ziplineCreated, manifestReady, and codeLoadSkippedNotFresh event callbacks to Treehouse EventListener.

Changed:

  • The Treehouse Zipline disk cache directory is no longer within the cache directory on Android. This ensures it can't be cleared while the app is running. Zipline automatically constrains the directory to a maximum size so old entires will still be purged automatically.
  • Set the Zipline thread's stack size to 8MiB on Android to match iOS.
  • Use margin-inline-start and margin-inline-end for the start and end margin, respectively, for the HTML DOM layout bindings.
  • TestRedwoodComposition now accepts only the initial UiConfiuration and exposes a MutableStateFlow for changing its value over time.
  • TreehouseLayout now defines a default ID to allow state saving and restoration to work. Note that this will only work when a single instance is present in the hierarchy. If you have multiple, supply your own unique IDs.
  • Emoji Search sample applications now bundle the latest guest code at compile-time and do not require the server running to work.
  • The built-in RedwoodView for HTMLElement now reports density changes to the UiConfiguration.
  • Redwood protocol modules have been renamed to 'guest' and 'host' to match Treehouse conventions.
  • Suppress deprecation warnings in generated code. This code often refers to user types which may be deprecated, and should not cause additional warnings.
  • TreehouseAppContent.preload is now idempotent.
  • LazyList on iOS has changed from UICollectionView to UITableView, and changes to the backing data are now reported granularly rather than reloading everything.
  • Allow arbitrary serializable content within rememberSaveable inside Treehouse.
  • Add a TreehouseApp argument to CodeListener. Combined with the new uncaught exception callback, this provides an easy way to restart a Treehouse application on a crash.
  • EventListener.Factory instances are now supplied as part of a TreehouseApp instead of a TreehouseAppFactory. This more closely scopes them with the lifetime of the Zipline instance.

Fixed:

  • Ensure changes to modifiers notify their parent widget when using Treehouse.
  • Explicitly mark the generated scope objects as @Stable to prevent needless recomposition.
  • Dispose the old composition when the RedwoodContent composable recomposes or is removed from the composition.
  • Ensure UIViewChildren indexes children using typedArrangedSubviews when removing views from a UIStackView.
  • Correctly parse data object modifiers in the schema.
  • Remember the default CodeListener for TreehouseContent to avoid unneccessary recomposition on creation.
  • When calling TreehouseUi.start, fall back to older API signature when newer one does not match. This is needed because an addiitonal parameter was added in newer versions, but older guest code may have the old signature.
  • Persist saved values from Treehouse without jumping back to the UI thread which allows proper restoration after a config change.
  • Reset the requested widths and heights of a layout in the underlying Yoga engine when the size is invalidated. This ensures that the engine will properly measure changed content the grows and shrinks in either dimension.

This version works with Kotlin 1.9.22 by default.
