  59 This documentation is for LuaJIT 2.0.5. Please check the <tt>doc</tt>
  60 directory in each git branch for the version-specific documentation.
  61 </p>
  62 <p>
  63 The currently developed branches are LuaJIT&nbsp;2.1 and LuaJIT&nbsp;2.0.
  64 </p>
  65 <p>
  66 LuaJIT&nbsp;2.0 is in feature-freeze &mdash; new features will only
  67 be added to LuaJIT&nbsp;2.1.
  68 </p>

  70 <h2>Current Status</h2>
  71 <p>
  72 LuaJIT ought to run all Lua&nbsp;5.1-compatible source code just fine.
  73 It's considered a serious bug if the VM crashes or produces unexpected
  74 results &mdash; please report this.
  75 </p>
  76 <p>
  77 Known incompatibilities and issues in LuaJIT&nbsp;2.0:
  78 </p>
  79 <ul>
  80 <li>
  81 There are some differences in <b>implementation-defined</b> behavior.
  82 These either have a good reason, are arbitrary design choices
  83 or are due to quirks in the VM. The latter cases may get fixed if a
  84 demonstrable need is shown.
  85 </li>
  86 <li>
  87 The Lua <b>debug API</b> is missing a couple of features (return
  88 hooks for non-Lua functions) and shows slightly different behavior
  89 in LuaJIT (no per-coroutine hooks, no tail call counting).
  90 </li>
  91 <li>
  92 Currently some <b>out-of-memory</b> errors from <b>on-trace code</b> are not
  93 handled correctly. The error may fall through an on-trace
  94 <tt>pcall</tt> or it may be passed on to the function set with
  95 <tt>lua_atpanic</tt> on x64.
  96 </li>
  97 </ul>
