This release adds Kotlin extensions for more ergonomic list rendering with HtmlFlow Value Slots. The new APIs support ordinary and indexed iteration while preserving existing engine behavior and compatibility.

Kotlin list rendering with Value Slots​

Templates can now use Element<T, Z>.forEachOf(...) and Element<T, Z>.forEachIndexedOf(...) to render repeated content with an idiomatic Kotlin API.

The extensions include:

  • Overloads with an explicit extractor from a model to Iterable<E>.
  • Convenience overloads for models that are already Iterable<E>.
  • Indexed iteration through Slot<Indexed<E>> for templates that need each item's position.

The behavior aligns with the Java-side forEachOf and forEachIndexedOf methods, including nested loops and conditionals. This lets you write cleaner Kotlin templates with less boilerplate while retaining repeatable renders and the same rendering guarantees.
