 # Change Log
 
+## 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)
+
+## v2.17.0
+
+* Add option to toggle Linux hardware acceleration - [#154](https://github.com/ReactiveCircus/android-emulator-runner/pull/154) @stevestotter
+
+## v2.16.0
+
+* Avoid wrapping script code in quotes - [#134](https://github.com/ReactiveCircus/android-emulator-runner/pull/134) @hostilefork
+* Add option to disable spellcheck - [#143](https://github.com/ReactiveCircus/android-emulator-runner/pull/143) @AfzalivE
+* Add support for arm64-v8a for Apple Silicon Macs - [#146](https://github.com/ReactiveCircus/android-emulator-runner/pull/146) @Jeehut
+
+## v2.15.0
+
+* Added support for specifying the number of cores to use for the emulator - [#130](https://github.com/ReactiveCircus/android-emulator-runner/pull/130).

 ## v2.14.3
 
 * Support `macos-11.0` (Big Sur) runner - [#124](https://github.com/ReactiveCircus/android-emulator-runner/pull/124).

 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).

 ## Can I use this action on Linux VMs?
 
-The short answer is yes but 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.
+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).
