+## 4.2.0
+
+* **Android:** `armeabi-v7a` (32-bit ARM) is now bundled for Python **3.13** and **3.14**, not just 3.12 — `flet-dev/python-build` `20260630` publishes 32-bit ARM runtimes for those minors (built with `dart_bridge` **1.4.1**). The `package` command's hardcoded "3.12-only" `armeabi-v7a` skip is replaced by a manifest-driven check against each minor's `PythonRelease.androidAbis`, so the wheel fan-out (and the Android plugin's `abiFilters`) follow whatever python-build publishes per minor.
+* Bundle **3.12.13 / 3.13.14 / 3.14.6** (python-build `20260630`; CPython-standalone `20260623`); Pyodide **0.27.7 / 0.29.4 / 314.0.1** (3.14 bumped 314.0.0 → 314.0.1).
+
 ## 4.1.1
 
 * **Android:** fix two startup crashes — apps crashing on launch on Android 8.1 and below (API < 28) due to an unguarded `getLongVersionCode()` call, and the interpreter failing to start on a non-primary ABI (e.g. an x86_64 emulator) with `ModuleNotFoundError: No module named '_sysconfigdata__android_<arch>-linux-android'`. See `serious_python_android` 4.1.1.

+* **`armeabi-v7a` (32-bit ARM) is now bundled for Python 3.13 and 3.14**, not just 3.12. `flet-dev/python-build` `20260630` publishes 32-bit ARM runtimes for those minors (built with `dart_bridge` **1.4.1**), so the per-minor `android_abis` in `python_versions.properties` now include `armeabi-v7a` across the board and `defaultConfig.ndk.abiFilters` + the per-ABI download/copy fan-out pick it up automatically — no Gradle change needed.
+
 ## 4.1.1
 
 * Fix app crashing on launch on Android 8.1 and below (API < 28). The `getAppVersion` method-channel handler, called on every startup, used `PackageInfo.getLongVersionCode()` (API 28+) unconditionally. R8 outlines this call into a synthetic class that it can merge with other API 28+ outlines — notably Flutter 3.41's `ImageDecoder`-based image decoder — and invoking that merged class on API < 28 fails verification with `NoClassDefFoundError: android.graphics.ImageDecoder$OnHeaderDecodedListener`. The call is now guarded with a `Build.VERSION.SDK_INT` check, falling back to the deprecated `versionCode` int field on older devices.
