| Announcements |
| ------------- |
| |
| * GCC is no longer supported. It will be removed in NDK r18. |
| |
| * `libc++` is now the default STL for CMake and standalone toolchains. If you |
| manually selected a different STL, we strongly encourage you to move to |
| `libc++`. Note that ndk-build still defaults to no STL. For more details, see |
| [this blog post](https://android-developers.googleblog.com/2017/09/introducing-android-native-development.html). |
| |
| * gnustl, gabi++, and stlport have been removed. |
| |
| * Support for ARMv5 (armeabi), MIPS, and MIPS64 has been removed. Attempting to |
| build any of these ABIs will result in an error. |
| |
| * Support for ICS (android-14 and android-15) has been removed. Apps using |
| executables no longer need to provide both a PIE and non-PIE executable. |
| |
| * 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). |

| NDK |
| --- |
| |
| * Updated Clang to build 4393122 based on ??? |
| * AArch64 now uses gold by default, matching the other architectures. |
| * Updated gtest to upstream revision 0fe96607d85cf3a25ac40da369db62bbee2939a5. |
| * Fixed parsing of the NDK revision in CMake. NDK version information is now |
| available in the following CMake variables: |
| * `ANDROID_NDK_REVISION`: The full string in the source.properties file. |
| * `ANDROID_NDK_MAJOR`: The major revision of the NDK. For example: the 16 |
| in r16b. |
| * `ANDROID_NDK_MINOR`: The minor revision of the NDK. For example: the b |
| (represented as 1) in r16b. |
| * `ANDROID_NDK_BUILD`: The build number of the NDK. This is 0 in the case |
| of a local development build. |
| * `ANDROID_NDK_BETA`: The beta version of the NDK. This is 0 for a stable |
| release. |
| |
| 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`. |
