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.
- New published module tree-structure-compose: a LazyTree composable for Compose
Multiplatform (JVM/desktop, iOS, Wasm) with lazy rendering and expand/collapse.
- Fix an O(n^2) regression in addChild(): only walk ancestors for cycle detection
when the child already has a subtree (a fresh leaf can never form a cycle), so
building deep trees is O(n) again. Caught by the deep-chain stack-safety test on JS.
- README: Compose usage section; align all install snippets to 4.0.0.
- Version catalog: Compose Multiplatform + compose-compiler plugins.
Verified locally: JVM, JS(node), Wasm(node), iOS-simulator tests + apiCheck all green;
Compose module compiles for JVM, Wasm and iOS.
v3.4 modernization (continued):
- Migrate to Kotlin 2.x (K2); introduce gradle/libs.versions.toml version catalog;
simplify the JS/Wasm/Node and iOS source-set wiring for the K2 hierarchy template.
- Apply binary-compatibility-validator and Kover plugins.
- New published module tree-structure-serialization: @Serializable TreeNodeDto with
toDto()/toTreeNode() round-trip (kotlinx.serialization).
- New published module tree-structure-coroutines: asFlow()/pre/post/levelOrderFlow()
(kotlinx.coroutines Flow traversal).
- Docs: README examples for Sequence/navigation/functional APIs, class-level KDoc
(thread-safety/complexity), and a CHANGELOG.md.
- Ignore subproject build/ directories.
- Bump version to 3.4.0.
All JVM tests green (core + both modules).
