+      <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.
+             For more information on this change, see the
+             <a href="https://code.google.com/p/address-sanitizer/wiki/Android">Address
+             Sanitizer</a> project.</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 in
