       <dt>Important changes:</dt>
+      <dl>
       <dd>
       <ul>
-        <li>Made GCC 4.8 the default for all 32-bit ABIs.  Deprecated GCC 4.6, and
-            will remove it next release. To restore previous behavior, either add
-            <code>NDK_TOOLCHAIN_VERSION=4.6</code> to ndk-build, or
-            add <code>--toolchain=arm-linux-androideabi-4.6</code> when executing
-            <code>make-standalone-toolchain.sh</code> on the command line. GCC 4.9 remains the
-            default for 64-bit ABIs.</li>
-
-         <li>Stopped all x86[_64] toolchains from adding <code>-mstackrealign</code> by default. The
-             NDK toolchain assumes a 16-byte stack alignment. The tools and options used by default
-             enforce this rule. A user writing assembly code must make sure to preserve stack
-             alignment, and ensure that other compilers also comply with this rule.
-             (GCC bug <a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=38496">38496</a>)</li>
-
-         <li>Added Address Sanitizer functionality to Clang 3.5 support to the ARM and x86 ABIs.
-             More information on this change is available
-             <a href="https://code.google.com/p/address-sanitizer/wiki/Android">here</a>.</li>
-
-         <li>Introduced the requirement, starting from API level 21, to use <code>-fPIE -pie
-             </code> when building. In API levels 16 and higher, ndk-build uses <code>PIE</code>
-             when building. This change has a number of implications, which are discussed
-             <a href="https://code.google.com/p/android-developer-preview/issues/detail?id=888">here</a>.
-             These implications do not apply to shared libraries.</li>
+        <li>Integrated the workaround for Cortex-A53 Erratum 843419 into the
+        <code>aarch64-linux-android-4.9</code> linker. For more information on this workaround, see
+        <a href="https://sourceware.org/ml/binutils/2015-03/msg00446.html">Workaround for cortex-a53
+        erratum 843419.</a></li>
+
+         <li>Added Clang 3.6; <code>NDK_TOOLCHAIN_VERSION=clang</code> now picks that version
+         of Clang by default.</li>
+
+         <li>Removed Clang 3.4.</li>
+
+         <li>Removed GCC 4.6.</li>
+
+         <li>Implemented multithreading support in <code>ld.gold</code> for all architectures. It can
+         now link with or without support for multithreading; the default is to do it without.
+            <ul>
+            <li>To compile with multithreading, use the <code>--threads</code> option.</li>
+            <li>To compile without multithreading:, use the <code>--no-threads</code> option.</li>
+            </ul>
+            </li>
+
+         <li>Upgraded GDB/gdbserver to 7.7 for all architectures.</li>
+
+         <li>Removed the NDK package for 32-bit Darwin.</li>
       </ul>

      <dt>Important bug fixes:</dt>
      <dd>
      <ul>
-        <li>Made more fixes related to
-            <a href="https://gcc.gnu.org/ml/gcc-patches/2014-10/msg00906.html">
-            A53 Errata #835769</a> in the aarch64-linux-android-4.9 linker. As part of this, GCC
-            passes a new option, <code>--fix-cortex-a53-835769</code>, when
-            <code>-mfix-cortex-a53-835769</code> (enabled by default) is specified.
-            For more information, see
-            <a href="https://sourceware.org/ml/binutils/2014-10/msg00198.html">this page</a> and
-            <a href="https://sourceware.org/ml/binutils/2014-11/msg00287.html">this page</a></li>
-
-        <li>Documented a fix to a libc++ <code>sscanf/vsscanf</code> hang that occurred in API level
-            21. The fix itself had been implemented in r10c.
-            (Issue <a href="http://b.android.com/77988">77988</a>)</li>
-
-        <li>Fixed an AutoFDO (<code>-fauto-profile</code>) crash that occurred with GCC 4.9 when
-            <code>-Os</code> was specified. (Issue <a href="http://b.android.com/77571">77571</a>)</li>
+        <li>Fixed a crash that occurred when there were OpenMP loops outside of the main thread.</li>
+
+        <li>Fixed a GCC 4.9 internal compiler error (<i>ICE</i>) that occured when the user declared
+        <code>#pragma GCC optimize ("O0")</code>, but had a different level of optimization specified
+        on the command line. The <code>pragma</code> takes precedence.</li>
+
+        <li>Fixed an error that used to produce a crash with the following error message:
+<pre>
+in add_stores, at var-tracking.c:6000
+</pre>
+        </li>
+
+        <li>Implemented a workaround for a Clang 3.5 issue in which LLVM auto-vectorization
+        generates <code>llvm.cttz.v2i64()</code>, an instruction with no counterpart in the ARM instruction
+        set. When the compiler generates this instruction, the following error message results:
+
+<pre>
+fatal error: error in backend: Cannot select: 0xd5d9098: v2i64 = cttz 0xd5c4698 [ORD=6] [ID=40] dbg:/path/to/file

      <dt>Other bug fixes:</dt>
      <dd>
      <ul>
         <li>Made the following header and library fixes:</li>
            <ul>
-        <li>Added <code>posix_memalign</code> to API level 16. Also, added a prototype in
-            <code>stdlib.h</code> to API levels 16 to 19.
-            (Issue <a href="http://b.android.com/77861">77861</a>.)</li>
-        <li>Fixed <code>stdatomic.h</code> so that it includes <code>&lt;atomic&gt;</code> only for
-            C++11.</li>
-        <li>Modified the following headers for standalone use: <code>sys/user.h</code>, and
-            <code>gl2ext.h</code>, <code>dlext.h</code>, <code>fts.h</code>, <code>sgidefs.h</code>
-            for API level 21.</li>
-        <li>Modified <code>sys/user.h</code> to rename <code>mxcsr_mask</code> as <code>mxcr_mask</code>,
-            and to change the data type for <code>u_ar0</code></li> from <code>unsigned long</code>
-            to </code>struct user_regs_struct*</code>.
-        <li>Changed <code>sysconf()</code> return value type from <code>int</code> to
-            <code>long</code>.</li>
+           <li>Fixed <code>PROPERTY_*</code> in <code>media/NdkMediaDrm.h</code>.</li>
+           <li>Fixed <code>sys/ucontext.h</code> for <code>mips64</code>.</li>

            </ul>
+           </li>
+
+        <li>Fixed a spurious array-bounds warning that GCC 4.9 produced for x86, and reenabled the
+        array bounds warning that GCC 4.9 had produced for ARM. The warning for ARM had
+        previously been unconditionally disabled.</li>
+
+        <li>Fixed Clang 3.5 for <code>mips</code> and <code>mips64</code> to create a writable
+            <code>.gcc_except_table</code> section, thus matching GCC behavior. This change allows you
+            to avoid the following linker warning:
 
-        <li>Fixed ndk-build's handling of <code>thumb</code> for <code>LOCAL_ARM_MODE</code>: In
-            r10d, ndk-build adds <code>LOCAL_LDFLAGS+=-mthumb</code> by default, unless one of the
-            following conditions applies:</li>
-          <ul>
-            <li><code>LOCAL_ARM_MODE</code> has been set equal to <code>arm</code>.</li>
-            <li>You are doing a debug build (with settings such as <code>APP_OPTIM=debug</code> and
-            <code>AndroidManifest.xml</code> containing <code>android:debuggable="true"</code>),
-            where ARM mode is the default in order to retain compatibility with earlier toolchains.
-            (Issue <a href="http://b.android.com/74040">74040</a>)</li>
-          </ul>
+<pre>

+</pre>
+            </li>
 
-        <li>Fixed <code>LOCAL_SRC_FILES</code> in ndk-build to use Windows absolute paths.
-            (Issue <a href="http://b.android.com/74333">74333</a>)</li>
+        <li>Backported a fix for <code>compiler-rt</code> issues that were causing crashes when Clang
+        compiled for <code>mips64</code>. For more information, see LLVM Issue
+        <a href="http://llvm.org/bugs/show_bug.cgi?id=20098">20098</a>.</li>
 
-        <li>Removed bash-specific code from ndk-gdb. (Issue <a href="http://b.android.com/73338">73338</a>)</li>
+        <li>Fixed Clang 3.5 crashes that occurred on non-ASCII comments. (Issue

-            (Issue <a href="http://b.android.com/74145">74145)</a></li>
+        <li>Fixed <code>stlport collate::compare</code> to return <code>-1</code> and <code>1</code>. Previously,
+        it had returned arbitrary signed numbers.</li>
 
-        <li>Revised documentation concerning a fix for <code>System.loadLibrary()</code> transitive
-            dependencies. (Issue <a href="http://b.android.com/41790">41790</a>)</li>
+        <li>Fixed <code>ndk-gdb</code> for 64-bit ABIs. (Issue
+        <a href="https://code.google.com/p/android/issues/detail?id=118300">118300</a>)</li>
 
-        <li>Fixed a problem that was preventing 64-bit packages from extracting on Ubuntu 14.04 and
-            OS X 10.10 (Yosemite). (Issue <a href="http://b.android.com/78148">78148</a>)</li>
+        <li>Fixed the crash that the HelloComputeNDK sample for RenderScript was producing on
+        Android 4.4 (Android API level 19). For more information, see
