Where can I find the change log for Android 4.0.4? I'm curious what changed in Android 4.0.4. Is there an official change log somewhere? It seems very well hidden.
It's just a maintenance update for bug fixes. This is the best I can find:

  Note: This system image includes support for emulator hardware
  graphics acceleration when used with SDK Tools r17 or higher. (more
