<li>x86/x64: Fix <tt>bit.*</tt> argument checking in interpreter.</li>
<li>Catch early out-of-memory in memory allocator initialization.</li>
<li>Fix data-flow analysis for paths leading to an upvalue close.</li>
<li>Fix check for missing arguments in <tt>string.format()</tt>.</li>
<li>Fix Solaris/x86 build (note: not a supported target).</li>
<li>Fix recording of loops with instable directions in side traces.</li>
<li>x86/x64: Fix fusion of comparisons with <tt>u8</tt>/<tt>u16</tt>

</ul></li>
<li>FFI library:

<li>Add <tt>ffi.errno()</tt>. Save <tt>errno</tt>/<tt>GetLastError()</tt>
around allocations etc.</li>
<li>Fix <tt>__gc</tt> for VLA/VLS cdata objects.</li>
