-<span style="color: #0000c0;">LuaJIT&nbsp;2.0</span> is the current
-<span style="color: #0000c0;">stable branch</span>. This branch is in
-feature-freeze &mdash; new features will only be added to LuaJIT&nbsp;2.1.
-</p>
-
-<h2>Current Status</h2>
-<p>
-LuaJIT ought to run all Lua&nbsp;5.1-compatible source code just fine.
-It's considered a serious bug if the VM crashes or produces unexpected
-results &mdash; please report this.
-</p>
-<p>
-Known incompatibilities and issues in LuaJIT&nbsp;2.0:
-</p>
-<ul>
-<li>
-There are some differences in <b>implementation-defined</b> behavior.
-These either have a good reason, are arbitrary design choices
-or are due to quirks in the VM. The latter cases may get fixed if a
-demonstrable need is shown.
-</li>
-<li>
-The Lua <b>debug API</b> is missing a couple of features (return
-hooks for non-Lua functions) and shows slightly different behavior
-in LuaJIT (no per-coroutine hooks, no tail call counting).
-</li>
-<li>
-Currently some <b>out-of-memory</b> errors from <b>on-trace code</b> are not
-handled correctly. The error may fall through an on-trace
-<tt>pcall</tt> or it may be passed on to the function set with
-<tt>lua_atpanic</tt> on x64. This issue will be fixed with the new
-garbage collector.
-</li>
-<li>
-LuaJIT on 64 bit systems provides a <b>limited range</b> of 47 bits for the
-<b>legacy <tt>lightuserdata</tt></b> data type.
-This is only relevant on x64 systems which use the negative part of the
-virtual address space in user mode, e.g. Solaris/x64, and on ARM64 systems
-configured with a 48 bit or 52 bit VA.
-Avoid using <tt>lightuserdata</tt> to hold pointers that may point outside
-of that range, e.g. variables on the stack. In general, avoid this data
-type for new code and replace it with (much more performant) FFI bindings.
-FFI cdata pointers can address the full 64 bit range.
-</li>
-</ul>
