+<ul>
+<li><tt>goto</tt> is a keyword and not a valid variable name anymore.</li>

+<p>
+Note: this provides only partial compatibility with Lua 5.2 at the
+language and Lua library level. LuaJIT is API+ABI-compatible with
+Lua&nbsp;5.1, which prevents implementing features that would otherwise
+break the Lua/C API and ABI (e.g. <tt>_ENV</tt>).

-Obviously there will be some <b>bugs</b> in a VM which has been
-rewritten from the ground up. Please report your findings together with
-the circumstances needed to reproduce the bug. If possible, reduce the

-There is no formal bug tracker at the moment. The best place for

-The x86 JIT compiler only generates code for CPUs with support for
-<b>SSE2</b> instructions. I.e. you need at least a P4, Core 2/i3/i5/i7,
-Atom or K8/K10 to get the full benefit.<br>
-If you run LuaJIT on older CPUs without SSE2 support, the JIT compiler
-is disabled and the VM falls back to the LuaJIT interpreter. This is faster
-than the Lua interpreter, but not nearly as fast as the JIT compiler of course.

-known incompatibilities with standard Lua:
-<ul>
-<li>
-The Lua <b>debug API</b> is missing a couple of features (return
-hooks for non-Lua functions) and shows slightly different behavior

-Some of the <b>configuration options</b> of Lua&nbsp;5.1 are not supported:

-<li>The <b>number type</b> cannot be changed (it's always a <tt>double</tt>).</li>
-<li>The stand-alone executable cannot be linked with <b>readline</b>
-to enable line editing. It's planned to add support for loading it
-on-demand.</li>
-</ul>
-</li>
-<li>
-Most other issues you're likely to find (e.g. with the existing test
-suites) are differences in the <b>implementation-defined</b> behavior.
-These either have a good reason (like early tail call resolving which
-may cause differences in error reporting), are arbitrary design choices

-Roadmap 2012/2013</a> for the latest release plan. Here's the general
-project plan for LuaJIT 2.0:
+Roadmap 2012/2013</a> for details.
+</p>
+<p>
 </p>
-<ul>
-<li>
-The main goal right now is to stabilize LuaJIT 2.0 and get it out of
-beta test. <b>Correctness</b> has priority over completeness. This
-implies the first stable release will certainly NOT compile every
-library function call and will fall back to the interpreter from time
-to time. This is perfectly ok, since it still executes all Lua code,
-just not at the highest possible speed.
-</li>
-<li>
-The next step is to get it to compile more library functions and handle
-more cases where the compiler currently bails out. This doesn't mean it
-will compile every corner case. It's much more important that it
-performs well in a majority of use cases. Every compiler has to make
-these trade-offs &mdash; <b>completeness</b> just cannot be the
-overriding goal for a low-footprint, low-overhead JIT compiler.
-</li>
-<li>
-More <b>optimizations</b> will be added in parallel to the last step on
-an as-needed basis. Sinking of stores
-to aggregates and sinking of allocations are high on the list.
-More complex optimizations with less pay-off, such as value-range-propagation
-(VRP) will have to wait.
-</li>
-<li>
-LuaJIT 2.0 has been designed with <b>portability</b> in mind.
-Nonetheless, it compiles to native code and needs to be adapted to each
-architecture. The two major work items are porting the the fast interpreter,
-which is written in assembler, and porting the compiler backend.
-Most other portability issues like endianess or 32 vs. 64&nbsp;bit CPUs
-have already been taken care of.<br>
-Several ports are already available, thanks to the
-<a href="http://luajit.org/sponsors.html"><span class="ext">&raquo;</span>&nbsp;LuaJIT sponsorship program</a>.
-More ports will follow in the future &mdash; companies which are
-interested in sponsoring a port to a particular architecture, please
-use the given contact address.
-</li>
-<li>
-<b>Documentation</b> about the <b>internals</b> of LuaJIT is still sorely
-missing. Although the source code is included and is IMHO well
-commented, many basic design decisions are in need of an explanation.
-The rather un-traditional compiler architecture and the many highly
-optimized data structures are a barrier for outside participation in
-the development. Alas, as I've repeatedly stated, I'm better at
-writing code than papers and I'm not in need of any academic merits.
-Someday I will find the time for it. :-)
-</li>
-<li>
-Producing good code for unbiased branches is a key problem for trace
-compilers. This is the main cause for "trace explosion".
-<b>Hyperblock scheduling</b> promises to solve this nicely at the
-price of a major redesign of the compiler. This would also pave the
-way for emitting predicated instructions, which is a prerequisite
-for efficient <b>vectorization</b>.
