2020.3.17f1 Release Notes

Features

  • Android: Added more complete support for running Android apps on the Chrome OS platform. These changes enable building and running Android on x86 and x86-64 CPUs, now officially supported on Chrome OS devices. These changes also include input-related and windowing improvements for Chrome OS.

Improvements

  • Android: Added boot-config/command-line switch "platform-android-cpucapacity-threshold" that can be used to specify which CPU cores are treated as big cores.
