   into everyone's system when I do a "cvs update".) When no
   customize-target-features.lisp file exists, the target *FEATURES* list
   should be constructed the same way as before.
-* The QUIT debugger command is gone, since it did something
-  rather different than the SB-EXT:QUIT command, and since it never
-  worked properly outside the main toplevel read/eval/print loop.
-  Invoking the new TOPLEVEL restart provides the same functionality.
-* The GO debugger command is also gone, since you can just invoke
-  the CONTINUE restart directly instead.
-* The TOP debugger command is also gone, since it's redundant with 
-  'f 0', and since it interfered with abbreviations for the TOPLEVEL
-  restart.
-?? signal handling reliability
-?? fixed some bugs mentioned in the man page:
-  ?? DEFUN-vs.-DECLAIM
+* fixed bug 1 (error handling before read-eval-print loop starts), and
+  redid debugger restarts and related debugger commands somewhat while
+  doing so:
+  ** The QUIT debugger command is gone, since it did something
+     rather different than the SB-EXT:QUIT command, and since it never
+     worked properly outside the main toplevel read/eval/print loop.
+     Invoking the new TOPLEVEL restart provides the same functionality.
+  ** The GO debugger command is also gone, since you can just invoke
+     the CONTINUE restart directly instead.
+  ** The TOP debugger command is also gone, since it's redundant with the
+     FRAME 0 command, and since it interfered with abbreviations for the
+     TOPLEVEL restart.
+* fixed bugs in DEFCONSTANT ANSI-compatibility:
+  ** DEFCONSTANT now tests reassignments using EQL, not EQUAL, in order to 
+     warn about behavior which is undefined under the ANSI spec. Note: This
+     is specified by ANSI, but it's not very popular with programmers.
+     If it causes you problems, take a look at the new SB-INT:DEFCONSTANT-EQX
+     macro in the SBCL sources for an example of a workaround which you
+     might use to make portable ANSI-standard code which does what you want.
+  ** DEFCONSTANT's implementation is now based on EVAL-WHEN instead of on
+     pre-ANSI IR1 translation magic, so it does the ANSI-specified thing
+     when it's used as a non-toplevel form. (This is required in order
+     to implement the DEFCONSTANT-EQX macro.)
+  ** (DEFCONSTANT X 1) (DEFVAR X) (SETF X 2) no longer "works".
+  ** Unfortunately, non-toplevel DEFCONSTANT forms can still do some
+     funny things, due to bugs in the implementation of EVAL-WHEN
+     (bug #IR1-3). This probably won't be fixed until 0.7.x. (Fortunately,
+     non-toplevel DEFCONSTANTs are uncommon.)
+* The core file version number and fasl file version number have been 
+  incremented, because the old noncompliant DEFCONSTANT behavior involved
+  calling functions which no longer exist, and because I also took the
+  opportunity to chop an unsupported slot out of the DEBUG-SOURCE structure.
+* removed bug 21 from BUGS, since Martin Atzmueller points out that 
+  it doesn't seem to affect SBCL after all
+* The system now recovers better from non-PACKAGE values of the *PACKAGE*
+  variable.
+* The system now understands compound CONS types (e.g. (CONS FIXNUM T))
+  as required by ANSI. (thanks to Douglas Crosher's CMU CL patches, with
+  some porting work by Martin Atzmueller)
