  <ul>
-  <li> <p>Error handling has been added to external formats.  Previously,
-      all external formats would silently replace bad encodings with a
-      suitable replacement character.  Now, the user can specify how
-      the errors are handled by using the <tt>:DECODING-ERROR</tt> and
-      <tt>:ENCODING-ERROR</tt> parameters to <tt>OPEN</tt>.  The default is the previous
-      behavior.</p>
-	    
-      <p>For decoding-error, a character, symbol, or function
-      can be given.  If a character, then that character is used as
-      the replacement character.  For a symbol or function, it must be
-      a function of 3 arguments:  a message string, the offending
-      octet (or nil), and the number of octets read in the encoding.
-      If the function returns, it must be the codepoint of the desired
-      replacement.</p>

-    <li> Add <tt>EXT:LIST-ALL-EXTERNAL-FORMATS</tt> to list all known external
-      formats and their aliases.
-    </li>
-    <li> ADD <tt>EXT:DESCRIBE-EXTERNAL-FORMAT</tt> to print a description of the
-      specified exernal format.  To support this, the macros
-      <tt>DEFINE-EXTERNAL-FORMAT</tt> and <tt>DEFINE-COMPOSING-EXTERNAL-FORMAT</tt> have
-      changed.
-    </li>
-    <li> The sparc port now supports the :executable feature.</li>
-    <li> The Mac OS X port now support the :executable feature.</li>
-    <li> A critical bug in the fast unicode stream buffering routine has
-      been fixed.  This bug manifests itself by causing valid
-      sequences to be incorrectly decoded, resulting in a replacement
-      character.
-    <li> UTF-8 correctly catches overlong sequences now.  Previously,
-      overlong sequences were missed.
-    <li> When UTF-8 decoder encounters an overlong sequence, a surrogate
-      code point, or a too-large codepoint, the entire sequence is
-      converted to the replacement character.  Previously, all of the
-      octets except the first were put back, and the data read again.
-    <li> Some GC improvements for sparc and ppc.  (Changes for ppc
-      untested).  GC could incorrectly move the PC and other
-      registers, causing a segfault.
-    <li> A bug inadvertently introduced in the 2010-04 non-unicode
-      snapshot has been fixed.  The bug prevented the non-unicode
-      versions of CMUCL from loading the external format aliases
-      file. 
-    <li> With SSE2, the imaginary part of a (complex single-float) is now
-      returned correctly.
-    <li> The method used to create executable images for Linux has been
-      cleaned up and should be far more robust against different
-      versions of the OS.  The same is true on sparc as well as Mac OS
-      X.
+  <li> It is possible to hash NaNs (IEEE Not-a-Number)
+  </li>
+  <li> For SSE2 builds, = no longer signals an error if one operand is
+  NaN.  This matches what happens for x87.
+  </li>
+  <li> For SSE2 builds, <code>SIGCONTEXT-FLOAT-REGISTER</code> returned the wrong
+  value for single-floats.  Easily noticead when tracing a function
+  with single-float arguments. 
+  </li>
+  <li> Trac issue #36: file-position broken for utf16 and utf32. 
+       <code>FILE-POSITION</code> returns the correct value for UTF16
+       and UTF32 when there is a BOM (byte-order mark) at the
+       beginning of the file.
+  </li>
