<ul>
<li>New features:
<ul>
<li>PowerPC/e500v2 port of the LuaJIT interpreter is complete.</li>
<li>Various minor features from Lua 5.2: Hex escapes in literals,
<tt>'\*'</tt> escape, reversible <tt>string.format("%q",s)</tt>,
<tt>"%g"</tt> pattern, <tt>table.sort</tt> checks callbacks,
<tt>os.exit(status|true|false[,close])</tt>.</li>
<li>Lua 5.2 <tt>__pairs</tt> and <tt>__ipairs</tt> metamethods
(disabled by default).</li>
<li>Initial release of the FFI library.</li>
</ul></li>
<li>Correctness and completeness:
<ul>
<li>Fix <tt>string.format()</tt> for non-finite numbers.</li>
<li>Fix memory leak when compiled to use the built-in allocator.</li>
<li>x86/x64: Fix unnecessary resize in <tt>TSETM</tt> bytecode.</li>
<li>Fix various GC issues with traces and <tt>jit.flush()</tt>.</li>
<li>x64: Fix fusion of indexes for array references.</li>
<li>x86/x64: Fix stack overflow handling for coroutine results.</li>
<li>Enable low-2GB memory allocation on FreeBSD/x64.</li>
<li>Fix <tt>collectgarbage("count")</tt> result if more than 2GB is in use.</li>
<li>Fix parsing of hex floats.</li>
<li>x86/x64: Fix loop branch inversion with trailing
<tt>HREF+NE/EQ</tt>.</li>
<li>Add <tt>jit.os</tt> string.</li>
<li><tt>coroutine.create()</tt> permits running C functions, too.</li>
<li>Fix OSX build to work with newer ld64 versions.</li>

<li>Improve bytecode coalescing of <tt>nil</tt> constants.</li>
<li>Compile calls to vararg functions.</li>
<li>Compile <tt>select()</tt>.</li>
<li>Improve alias analysis, esp. for loads from allocations.</li>
<li>Tuning of various compiler heuristics.</li>
<li>Refactor and extend IR conversion instructions.</li>
<li>x86/x64: Various backend enhancements related to the FFI.</li>
