+## 0.8.6
+
+* Added `com.flet.serious_python_android.PythonActivity` holder class with `mActivity` holding a reference to an app MainActivity. Needed for `plyer`.
+* Android plugin sets `MAIN_ACTIVITY_HOST_CLASS_NAME` environment variable with the name of activity holder class name (`com.flet.serious_python_android.PythonActivity`).
+* Android plugin sets `MAIN_ACTIVITY_CLASS_NAME` environment variable with a class name of an app MainActivity.
+* Android plugin sets `ANDROID_NATIVE_LIBRARY_DIR` environment variable with the path to a directory containing app .so libraries. Needed for patching `ctypes.find_library`.
+* Changed behavior of `SERIOUS_PYTHON_ALLOW_SOURCE_DISTRIBUTIONS` environment variable that should contain a comma-separated list of packages to allow installation from source distribution.
+* Fixed: iOS `site-packages` to `xcframeworks` migration script supports both `library.so` and `library.{something}.so`.
+
 ## 0.8.5
 
 * Added Java `loadLibrary` to Android plugin to support `pyjnius` ([#128](https://github.com/flet-dev/serious-python/issues/128)).

+* Android plugin sets `MAIN_ACTIVITY_HOST_CLASS_NAME` environment variable with the name of activity holder class name (`com.flet.serious_python_android.PythonActivity`).
+* Android plugin sets `MAIN_ACTIVITY_CLASS_NAME` environment variable with a class name of an app MainActivity.
+* Android plugin sets `ANDROID_NATIVE_LIBRARY_DIR` environment variable with the path to a directory containing app .so libraries. Needed for patching `ctypes.find_library`.
+* Changed behavior of `SERIOUS_PYTHON_ALLOW_SOURCE_DISTRIBUTIONS` environment variable that should contain a comma-separated list of packages to allow installation from source distribution.
+* Fixed: iOS `site-packages` to `xcframeworks` migration script supports both `library.so` and `library.{something}.so`.
