    <p><b>2.1.3 (August 2016)</b>
    </p>
    <p>
      This update adds compatibility with Gradle 2.14.1, which includes performance
      improvements, new features, and an important <a href=
      "https://docs.gradle.org/2.14/release-notes#local-privilege-escalation-when-using-the-daemon"
      class="external-link">security fix</a>. For more details, see the <a href=

      release notes</a>.
    </p>
    <p>
      By default, new projects in Android Studio 2.1.3 use Gradle 2.14.1. For
      existing projects, the IDE prompts you to upgrade to Gradle 2.14.1 and
      <a href="/studio/releases/gradle-plugin.html#revisions">Android plugin
      for Gradle 2.1.3</a>, which is required when using Gradle 2.14.1 and
      higher.

**2.1.2 (June 2016)**


This update includes a number of small changes and bug fixes:

- [Instant Run](https://developer.android.com/studio/run#instant-run) updates and bug fixes.
- Improvements to LLDB performance and crash notifications.
- Fixed a regression in the Android Studio 2.1.1 security update that caused `git rebase` to fail.

<br />

<br />

**2.1.1 (May 2016)**

Security release update.

<br />

<br />

The Android N platform adds support for [Java 8 language features](https://developer.android.com/studio/write/java8-support), which
require a new experimental compiler called Jack. The latest version of Jack is
currently supported only in Android Studio 2.1. So if you want to use Java 8
language features, you need to use Android Studio 2.1 to build your app.

<br />

<br />

**Note:** [Instant Run](https://developer.android.com/tools/building/building-studio#instant-run)
is disabled when you enable the Jack compiler because they currently are not
compatible.

<br />

<br />

Although Android Studio 2.1 is now stable, the Jack compiler is still
experimental and you must enable it with the `jackOptions`
property in your `build.gradle` file.

<br />

<br />

Other than the changes to support the N Preview, Android Studio 2.1
includes minor bug fixes and the following enhancements:

- The Java-aware C++ debugger is now enabled by default when you're using an N device or emulator and select **Native** debugger mode (in the **Debugger** tab for your run/debug configuration).

For other build enhancements, including incremental Java compilation
and dexing-in-process,update your [Android plugin for
Gradle](https://developer.android.com/tools/revisions/gradle-plugin) to version 2.1.0.
