+ <dt>Important changes:</dt>
+ <dd>
+ <ul>
+ <li>Added 64-bit host toolchain set (package name suffix {@code *-x86_64.*}). For more
+ information, see {@code CHANGES.HTML} and {@code NDK-BUILD.html}.</li>
+ <li>Added Clang 3.2 compiler. GCC 4.6 is still the default. For information on using the
+ Clang compiler, see {@code CHANGES.HTML}.</li>
+ <li>Added static code analyzer for Linux/MacOSX hosts. For information on using the
+ analyzer, see {@code CHANGES.HTML}.</li>
+ <li>Added MCLinker for Linux/MacOSX hosts as an experimental feature. The {@code ld.gold}
+ linker is the default where available, so you must explicitly enable it. For more
+ information, see {@code CHANGES.HTML}.</li>
+ <li>Updated ndk-build to use topological sort for module dependencies, which means the
+ build automatically sorts out the order of libraries specified in
+ {@code LOCAL_STATIC_LIBRARIES}, {@code LOCAL_WHOLE_STATIC_LIBRARIES} and
+ {@code LOCAL_SHARED_LIBRARIES}. For more information, see {@code CHANGES.HTML}.
