 # Change Log
 
-## v2.1.0
-
-* Added support for multi-line script.
-
-## v2.0.0
-
-* Added action input `emulator-options` for providing command-line options used when launching the emulator. Default value is `-no-window -no-snapshot -noaudio -no-boot-anim`.
-* Removed `headless` action input which is equivalent to specifying `-no-window` in the new `emulator-options` action input (included by default).
-
 ## v1.0.2
 
 * Increased emulator boot timeout to **5 mins**.

 A GitHub Action for installing, configuring and running Android Emulators on macOS virtual machines.
 
-The old ARM-based emulators were slow and are no longer supported by Google. The modern Intel Atom (x86 and x86_64) emulators require hardware acceleration (HAXM on Mac & Windows, QEMU on Linux) from the host to run fast. This presents a challenge on CI as to be able to run hardware accelerated emulators within a docker container, **KVM** must be supported by the host VM which isn't the case for cloud-based CI providers due to infrastructural limits. If you want to learn more about this, here's an article I wrote: [Running Android Instrumented Tests on CI](https://dev.to/ychescale9/running-android-emulators-on-ci-from-bitrise-io-to-github-actions-3j76).

 The **masOS** VM provided by **GitHub Actions** has **HAXM** installed so we are able to create a new AVD instance, launch an emulator with hardware acceleration, and run our Android 
 tests directly on the VM.
