 <h2 id="changes">Change log</h2>
 
 <p>
-  Apr-2012
-  <ul>
-    <li>improved LuaJIT2 compatibility by handling "*" library set through luaL_openlibs().</li>
-  </ul>
-
-
-  Feb-2012
-  <ul>
-    <li>Added support for an on_state_create callback invoked on a pristine Lua state created by Lanes.</li>
-    <li>This required a change in the <tt>lanes.configure()</tt> signature, hence the minor version bump.</li>
-  </ul>
-
-
-  Nov-2011
-  <ul>
-    <li>process exit change: close everything at GC when main state closes, not when atexit() handlers are processed</li>
-    <li>Lua 5.2-style module:</li>
-    <ul>
-      <li>module() is no longer used to implement lanes.lua</li>
-      <li>a global "lanes" variable is no longer created when the module is required</li>
-      <li>the Lanes module table is returned instead</li>
-    </ul>
-    <li>Lanes must be initialized before used:</li>
-    <ul>
-      <li>the first occurence of 'require "lanes"' produces a minimal interface that only contains a configure() function</li>
-      <li>the remainder of the interface is made available once this function is called</li>
-      <li>subsequent calls to configure() do nothing</li>
-      <li>configure() controls the number of keeper states and the startup of timers</li>
-    </ul>
-    <li>* LuaJIT 2 compatibility</li>
-    <ul>
-      <li>non-Lua functions are no longer copied by creating a C closure from a C pointer, but through 2-way lookup tables</li>
-      <li>this means that if a lane function body pulls non-Lua functions, the lane generator description must contain the list of libraries and modules that exports them</li>
-      <li>introduces a change in configuration .globals management: contents are copied *after* std libs are loaded</li>
-      <li>new .required configuration entry to list modules that must be require()'ed before lane body is transferred</li>
-    </ul>
-    <li>lane:cancel() wakes up waiting lindas like what is done at lane shutdown</li>
-    <li>removed packagepath and packagecpath options, replaced by a package table, whose fields path, cpath, loaders, preload are transfered</li>
-  </ul>
-
-  Mar-2011 (not yet versioned)
-  <ul>
-    <li>linda honors __tostring and __concat</li>
-    <li>new accessor linda:count(), to get info about data stored inside a linda.</li>
-    <li>new lanes options packagepath and packagecpath, in case one needs to set them differently than the default.</li>
-  </ul>
-
-  Mar-2011 (2.1.0)
-  <ul>
-  <li>fixed potential crash at application shutdown when calling lua_close() on a killed thread's VM.</li>
-  <li>exposed cancel_test() in the lanes to enable manual testing for cancellation requests.</li>
-  <li>removed kludgy {globals={threadName}} support, replaced with a new function set_debug_threadname().</li>
-</ul>
-Feb-2011 (2.0.11):
-  <ul>
-  <li>Fixed bug where reference to Linda object was dropped for a short time (crashing if GC was run during that time).</li>
-  <li>Changed the atexit code to trip the timer thread's write signal.</li>
-  <li>Changed lanes.c to export functions as a module rather than writing them directly to the globals table.</li>
-</ul>
-
-Jan-2011 (2.0.10):
-<ul>
-  <li>linda_send was waiting on the wrong signal</li>
