Advanced Profiling
------------------

Android Studio’s Advanced Profiling feature rewrites OkHttp bytecode for instrumentation.
Unfortunately it crashes on OkHttp 4.x’s bytecode. Until [Google’s bug][advanced_profiling_bug] is
fixed you must disable advanced profiling in Android Studio.

    Supporting a full decade of Android releases on our 3.12.x branch is tricky!


## Version 3.12.9

_2020-02-24_

 *  Fix: Don't crash on Android 11 due to use of restricted methods. This prevents a crash with the
    exception, "Expected Android API level 21+ but was 29".


## Version 3.12.8
