 # Change Log
 
+## v2.21.0
+
+* Support new [ATD](https://developer.android.com/studio/preview/features#gmd-atd) targets optimized to reduce CPU and memory resources when running instrumented tests: `aosp_atd`, `google_atd`. - [#198](https://github.com/ReactiveCircus/android-emulator-runner/pull/198). Note that currently these targets require the following:
+  * `api-level: 30`
+  * `arch: x86` or `arch: arm64-v8a`
+  * `channel: canary`
+
+## v2.20.0
+
+* Support non-mobile targets: `android-wear`, `android-wear-cn`, `android-tv` and `google-tv`. - [#180](https://github.com/ReactiveCircus/android-emulator-runner/pull/180) @alexvanyo.
+* Update SDK command-line tools to `5.0`. - [#174](https://github.com/ReactiveCircus/android-emulator-runner/pull/174)
+* Update build tools to `31.0.0`. - [#174](https://github.com/ReactiveCircus/android-emulator-runner/pull/174)
+* Add option to specify the `channel` to download SDK components from: `stable` (default), `beta`, `dev` and `canary`. - [#185](https://github.com/ReactiveCircus/android-emulator-runner/pull/185)
+
+## v2.19.1
+
+* Accept all Android SDK Licenses to fix `sdkmanager` installation. - [#172](https://github.com/ReactiveCircus/android-emulator-runner/pull/172) @marcuspridham.
+
+## v2.19.0
+
+* Add option to specify `ram-size` for the AVD. - [#165](https://github.com/ReactiveCircus/android-emulator-runner/pull/165).
+
+
+## v2.18.1
+
+* Added support for setting modern emulator build ids for `emulator-build`. Not all build ids are supported until we are able to figure out at which build id the download URL pattern changed. `7425822` (version 30.7.3) is currently the last known working build id.
+
+## v2.18.0
+
+* Add `force-avd-creation` which when set to `false` will skip avd creation if avd with same name exists. This enables AVD snapshot caching which can significantly reduce emulator startup time. See [README.md](https://github.com/ReactiveCircus/android-emulator-runner/blob/main/README.md#usage) for a sample workflow. - [#159](https://github.com/ReactiveCircus/android-emulator-runner/pull/159)

+
+* Support API 28 system images with `google_apis` or `google_apis_playstore` target - [#117](https://github.com/ReactiveCircus/android-emulator-runner/pull/117).
+
+## v2.14.1
+
+* Fix hang during AVD creation when `profile` is not specified - [#113](https://github.com/ReactiveCircus/android-emulator-runner/issues/113).

 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 short answer is yes but on Github-hosted Linux runners it's expected to be a much worse experience (on some newer API levels it might not work at all) than running it on macOS. You can get it running much faster on self-hosted Linux runners but only if the underlying instances support KVM (which most don't).
