## Announcements

 * [LLD](https://lld.llvm.org/) is now available for testing. AOSP is in the
   process of switching to using LLD by default and the NDK will follow
   (timeline unknown). Test LLD in your app by passing `-fuse-ld=lld` when
   linking.

 * The Play Store will require 64-bit support when uploading an APK beginning in
   August 2019. Start porting now to avoid surprises when the time comes. For
   more information, see [this blog post](https://android-developers.googleblog.com/2017/12/improving-app-security-and-performance.html).

## Known Issues

 * This is not intended to be a comprehensive list of all outstanding bugs.
 * [Issue 360]: `thread_local` variables with non-trivial destructors will cause
   segfaults if the containing library is `dlclose`ed on devices running M or
   newer, or devices before M when using a static STL. The simple workaround is
   to not call `dlclose`.
 * [Issue 70838247]: Gold emits broken debug information for AArch64. AArch64
   still uses BFD by default.
 * This version of the NDK is incompatible with the Android Gradle plugin
   version 3.0 or older. If you see an error like
   `No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android`,
   update your project file to [use plugin version 3.1 or newer]. You will also
   need to upgrade to Android Studio 3.1 or newer.
