+ CMUCL 20b prelease 1 has been released, in preparation for the
+ upcoming 20b release.  Therefore there will not
+ be a 2010-08 snapshot.
  <ul>
-  <li> DELETE-FILE, ENSURE-DIRECTORIES-EXIST, FILE-AUTHOR,
-  FILE-WRITE-DATE, and OPEN now merge the given pathname with
-  *DEFAULT-PATHNAME-DEFAULTS* as required by CLHS sec 19.2.3. 
-  </li>
-  <li> When printing out argument values in the debugger and also
-  during TRACE, the incorrect values were returned for the SSE2 core.
-  This was caused by using the x87 values instead of the sse2 values
-  in the sigcontext.  This is fixed now. </li>
+  <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>
