+* Update LLVM to clang-r416183c1, based on LLVM 12 development.
+ * [Issue 1540]: Fixed compiler crash when using coroutines.
+ * [Issue 1544]: Now uses universal binaries for M1 Macs.
+ * [Issue 1551]: Prevent each translation unit from receiving its own copy of
+ emulated thread-local global variables.
+ * [Issue 1555]: Fixed compiler crash for armeabi-v7a.
+* [Issue 1492]: ndk-build.cmd: Stop using make's `-O` (`--output-sync`) flag on
+ Windows to avoid `fcntl(): Bad file descriptor` error.
+* [Issue 1553]: Updated sysroot to latest Android 12.
+* [Issue 1569]: Fixed `-fno-integrated-as` not being able to find the assembler.
+* CMake changes:
+ * [Issue 1536]: Make optimization flags used with CMake more consistent.
+ Historically thumb release builds used `-Oz`, but AGP switched to using
+ `RelWithDebInfo` for release builds in the latest release which was not
+ using `-Oz`. To reduce per-arch differences and behavior differences
+ compared to CMake's defaults, `-Oz` use was removed. You may see code size
+ increases for armeabi-v7a due to this, but also increased optimization. To
+ restore the prior behavior, add `-Oz` to your cflags.
+ * [Issue 1560]: Fixed pull-up of unsupported API levels when using the new
+ CMake toolchain file. This affects CMake 3.21 and
+ `ANDROID_USE_LEGACY_TOOLCHAIN_FILE=ON` use cases, and was the common case
+ for AGP users with a `minSdkVersion` below 21.
+ * [Issue 1573]: Fixed `ANDROID_USE_LEGACY_TOOLCHAIN_FILE` not being obeyed
+ during CMake try-compile.
+ * [Issue 1581]: Added workaround for [CMake Issue 22647], which was causing
+ `MINGW` to be incorrectly defined by CMake when building for Android on a
+ Windows host. This only affected those using the Android toolchain file when
+ CMake 3.21 or newer was used. This likely was not a regression for users not
+ using the Android toolchain. The change will fix both use cases.

workaround will be necessary for this use case to work on all devices until

-* [Issue 1130]: When using `c++_static` and the deprecated linker with ndk-build
- with an `APP_PLATFORM` below 21, undefined references to operator new may
- occur. The fix is to use LLD.
-* 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.
-* [Issue 843]: Using LLD with binutils `strip` or `objcopy` breaks RelRO. Use
- `llvm-strip` and `llvm-objcopy` instead. This issue has been resolved in
- Android Gradle Plugin version 4.0 (for non-Gradle users, the fix is also in
- ndk-build and our CMake toolchain file), but may affect other build systems.
