 <h3>Detailed discussion</h3>
 
-<p>Guido van Rossum (the original creator of the Python language), 
-in conjunction with other python-core developers decided to use Python 3.x to
-clean up Python 2.x.  Python 2.x releases were careful to preserve backwards 
-compatibility with older versions, but Python 3.x was freed of this requirement.
-The most drastic improvement is better Unicode support (with 
-all text strings being Unicode by default) as well as saner 
-bytes/unicode separation.</p>
-
-<p>Several other aspects of the core language (such as <code>print</code>
-and <code>exec</code> being statements, integers using floor division) were 
-adjusted to be easier for newcomers to learn and to be more consistent 
-with the rest of the language, and old cruft has been removed (for 
-example, all classes are now new-style, <code>range()</code> returns a memory 
-efficient iterable and not a list as in 2.x).</p>
-
-<p>The <a href="http://docs.python.org/py3k/whatsnew/3.0.html">
-What's New in Python 3.0</a> document provides a good overview of the 
-major language changes and likely sources of incompatibility with 
-existing Python 2.x code.</p>

-<p>The <a href="http://docs.python.org/dev/whatsnew/3.1.html">What's
-New in Python 3.1</a>, 
+<p>Guido van Rossum (the original creator of the Python language), together
+with other python-core developers, decided to use Python
+3.x to clean up the Python language.  Python 2.x releases were always careful
+to preserve backwards compatibility with older versions, but Python
+3.0 was a clean-up that didn't have to carry old features.
+</p>
+
+<p>The major differences are:
+
+<ul>
+  <li> <b>Better Unicode support</b><br />
+   Unicode is now woven into the language, with
+all text strings being made Unicode by default.
+  <li> <b>Easier for newcomers</b><br />
+   Dividing integers always returns an accurate result.
+   Integers can handle any size, no longer limited to the machine's word size.
+   Comparison operators are simpler, and comparing different types
+   is now an error.
+   Catching exceptions in the <code>except:</code> statement is clearer.
+  <li> <b>Removed old features and complications</b><br />
+    All classes are now new-style.  <code>range()</code> and various
+    dictionary methods return a memory-efficient iterable and not a
+    list.  List comprehensions no longer leak the value for their looping
+    variable.
+  </li>
+</ul>
