Walkthrough

Bumps Kotlin from 2.3.21 to 2.4.0, KSP from 2.3.6 to 2.3.9, and compileSdk from 36 to 37. All other file changes are auto-generated consequences: binary API dumps across every module have lambda accessor method suffixes renamed to include LandscapistDemo, and Compose Stability Analyzer outputs reclassify several parameters from RUNTIME/UNSTABLE to UNKNOWN.

Changes

Kotlin 2.4.0 + compileSdk 37 toolchain upgrade

Layer / File(s)	Summary
Kotlin 2.4.0, KSP 2.3.9, compileSdk 37 version bumps gradle/libs.versions.toml, buildSrc/src/main/kotlin/com/github/skydoves/landscapist/Configuration.kt	Kotlin bumped from 2.3.21 → 2.4.0, KSP from 2.3.6 → 2.3.9, and compileSdk from 36 → 37.
Generated binary API dumps: LandscapistDemo suffix rename coil/api/coil.api, coil3/api/android/coil3.api, coil3/api/desktop/coil3.api, fresco/api/fresco.api, glide/api/glide.api, landscapist-image/api/*/landscapist-image.api, landscapist-image-gallery/api/*/landscapist-image-gallery.api	All ComposableSingletons lambda accessor method JVM names across every module gained a LandscapistDemo_ prefix in their suffix (e.g., $coil_release → $LandscapistDemo_coil_release).
Generated Compose Stability dumps: RUNTIME/UNSTABLE → UNKNOWN coil/stability/*, fresco/stability/*, fresco-websupport/stability/*, glide/stability/*, landscapist-transformation/stability/*	Parameters such as previewPlaceholder, key, ref, context, imageLoader, imageModel, imageBitmap, and painter are reclassified from RUNTIME or UNSTABLE to UNKNOWN in both debug and release stability dumps.

Poem

🐰 Hop, hop, the SDK grew,
From thirty-six to thirty-seven, brand new!
Kotlin leapt to two-point-four,
The lambdas gained a LandscapistDemo before.
Stability now reads UNKNOWN — how mysterious the view,
A rabbit rebuilt the world, and off to lunch it flew! 🥕
