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.
+* 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.
+* DEFCONSTANT has been made more ANSI-compatible (completely ANSI-compatible,
+ as far as I know):
+ ** 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.)
+?? fixed bug: (DEFCONSTANT X 1) (DEFVAR X) (SETF X 2) no longer "works".
+?? fixed bug 21, a compiler bug re. special variables in closures. One
+ consequence of this is that ILISP should work better, because idioms like
+ (LET ((*PACKAGE* ..)) (DO-SOMETHING)) no longer have screwy side-effects.
+* 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.
