Add the `android` target to the Compose Multiplatform library and a sensible
default renderer, so the largest Compose audience is a first-class consumer.
- Core `tree-structure` and `tree-structure-compose` now build and publish an
`-android` variant (compileSdk 35, minSdk 21). The core needs it too: its
inline `tree { }` DSL is built per target, and Android consumers (JVM 11/17)
cannot inline a JVM-21 build.
- `TreeNodeRow`: a foundation-only default node row (clickable, indented, with a
`▾`/`▸` marker, no Material dependency), plus a no-content `LazyTree(root,
label = …)` overload that uses it. The existing lambda overload is unchanged.
- New `samples` Android app module demonstrating `LazyTree` + `@Preview`
(not published; excluded from API validation).
- Toolchain: Gradle wrapper 8.5 -> 8.10.2, Android Gradle Plugin 8.7.2.
- binary-compatibility-validator now emits per-target dumps (api/jvm, api/android)
for the two multi-JVM-target modules; CI assembles the Android outputs.

# Changelog
|
||
|
||
All notable changes to this project are documented here. The format is based on
|
||
[Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this project adheres to
|
||
[Semantic Versioning](https://semver.org/spec/v2.0.0.html).
|
||
|
||
## [Unreleased]
|
||
|
||
### Added
|
||
- **Android target.** The core `tree-structure` module and `tree-structure-compose` now publish an
|
||
`-android` variant (`minSdk` 21), so both can be consumed directly in Android projects.
|
||
- `tree-structure-compose`: a foundation-only `TreeNodeRow` composable — a sensible default node row
|
||
(clickable, indented, with a `▾`/`▸` marker and no Material dependency) — plus a no-content
|
||
`LazyTree(root, label = …)` overload that renders each node with it. The existing lambda overload
|
||
is unchanged.
|
||
- A runnable Android sample app in the new `samples` module, with `@Preview` composables.
|
||
|
||
### Changed
|
||
- Upgraded the Gradle wrapper to 8.10.2 and introduced Android Gradle Plugin 8.7.2 (`compileSdk` 35).
|
||
No source or behavior changes to existing targets.
|
||
|
||
## [4.1.1] - 2026-06-08
|
||
|
||
### Fixed
|
||
- Restored the Apple/iOS artifacts (`iosArm64`, `iosX64`, `iosSimulatorArm64`) for the core and every
|
||
module. The release workflow published from a Linux runner, which cannot build Kotlin/Native Apple
|
||
targets, so they were silently omitted from 3.1.5–4.1.0; publishing now runs on macOS. No API or
|
||
behavior changes from 4.1.0 — this is a packaging fix only.
|
||
|
||
## [4.1.0] - 2026-06-07
|
||
|
||
### Added
|
||
- Structural mutation helpers on `TreeNode`: `insertChild`, `removeChildAt`, `replaceChild`,
|
||
`moveChild`, `addChildren`, and `sortChildren`.
|
||
- Tree query extensions: `lowestCommonAncestor`, `distance`, `pathBetween`, and `contains` for
|
||
finding common ancestors, edge distances, the path between two nodes, and value membership.
|
||
- Customizable `prettyString(connectors, render)` extension: choose connector glyphs via
|
||
`TreeConnectors` (`Default` box-drawing or `Ascii`) and supply a per-node renderer that receives
|
||
the value, its depth and whether it is its parent's last child. The all-defaults call is
|
||
byte-identical to the existing no-arg `prettyString()`.
|
||
- New `tree-structure-immutable` module: a persistent `ImmutableTreeNode` with structural sharing
|
||
(`addChild`/`removeChild`/`mapValues` return new roots; pre/post/level-order traversals,
|
||
`nodeCount`, and `height`).
|
||
|
||
### Changed
|
||
- Rewrote the README for clarity: one consistent example tree, task-oriented sections
|
||
(building, traversal, navigation, functional, utilities, mutating), per-module usage, and a
|
||
condensed maintainer "Releasing" section.
|
||
|
||
## [4.0.0]
|
||
|
||
A breaking release that cleans up the core API and enforces an explicit public surface.
|
||
|
||
### Changed (breaking)
|
||
- `TreeNode.treeIterator` is now a read-only `val` (set it via the constructor). Use
|
||
`iterator(order)` or `asSequence(order)` to traverse in a different order per call.
|
||
- `removeChild(child)` now only removes a **direct** child of the receiver (previously it removed
|
||
the node from its actual parent regardless). Use `child.detach()` to unhook a node from wherever
|
||
it lives.
|
||
- `addChild(child)` now throws `TreeNodeException` if `child` already has a parent or if the
|
||
attachment would create a cycle. Call `detach()` first to move a node.
|
||
- `clear()` no longer detaches the receiver from its own parent; it only removes its descendants.
|
||
- `path(descendant)` now returns `List<TreeNode<T>>?` (`null` when `descendant` is the root or not a
|
||
descendant) instead of throwing `TreeNodeException`.
|
||
|
||
### Added
|
||
- `TreeNode.detach()` — removes a node from its parent.
|
||
- `TreeNode.iterator(order)` — a one-shot iterator in a specific order.
|
||
- Strict `explicitApi()` mode across all modules.
|
||
- New `tree-structure-compose` module: a `LazyTree` composable for Compose Multiplatform.
|
||
|
||
### Migration
|
||
- `node.treeIterator = PostOrder; for (n in node) { … }` → `for (n in node.asSequence(PostOrder)) { … }`
|
||
- `root.removeChild(deepNode)` → `deepNode.detach()`
|
||
- `try { node.path(x) } catch (e: TreeNodeException) { … }` → `node.path(x)?.let { … }`
|
||
|
||
## [3.4.0]
|
||
|
||
### Added
|
||
- Lazy `Sequence` traversal: `asSequence(order)`, `preOrderSequence()`, `postOrderSequence()`,
|
||
`levelOrderSequence()` — composes with the Kotlin stdlib and short-circuits.
|
||
- Navigation extensions: `isLeaf`, `degree`, `root()`, `ancestors()`, `siblings()`, `leaves()`,
|
||
`descendants()`.
|
||
- Functional extensions: `findNode`, `filterNodes`, `anyNode`, `allNodes`, `countNodes`,
|
||
`foldNodes`, `mapValues`, `deepCopy`, `structurallyEquals` (all stack-safe).
|
||
- New optional modules published as separate artifacts:
|
||
- `tree-structure-serialization` — `kotlinx.serialization` support via a `TreeNodeDto`.
|
||
- `tree-structure-coroutines` — `Flow` traversal (`asFlow`, `preOrderFlow`, …).
|
||
- `CHANGELOG.md`, expanded README examples, and class-level KDoc (thread-safety / complexity).
|
||
|
||
### Changed
|
||
- `nodeCount()`, `height()`, `clear()` and the post-order iterator are now iterative — deep or
|
||
degenerate (linear) trees no longer throw `StackOverflowError`.
|
||
- Migrated to Kotlin 2.x (K2 compiler) and introduced a Gradle version catalog.
|
||
- Build now uses `binary-compatibility-validator` (committed `.api` baselines) and Kover.
|
||
|
||
## [3.1.5]
|
||
|
||
### Fixed
|
||
- Removed a stray `println` in `TreeNode.removeChild()` that printed to stdout on every removal.
|
||
|
||
### Removed
|
||
- Deleted the `Example.ws.kts` worksheet and the `kotlin("script-runtime")` dependency from the
|
||
published JVM artifact, plus the leftover `ExampleUnitTest` template test.
|
||
|
||
### Changed
|
||
- Bumped `actions/checkout` v2 → v4 in CI workflows.
|
||
|
||
## [3.1.4]
|
||
- Updated Kotlin and JS dependencies; added the `wasmJs` target.
|
||
|
||
## [3.1.3]
|
||
- iOS targets and Maven Central (Sonatype Central Portal) publishing.
