** CONSTANTP now returns true for all self-evaluating objects.
changes in sbcl-0.7.13 relative to sbcl-0.7.12:
+ * incompatible packaging change: in line with Unix convention,
+ SBCL now looks for its core file in /usr/{local/,}lib/sbcl/sbcl.core
+ if it's not in $SBCL_HOME. It also sets SBCL_HOME to match.
+ * REQUIRE and PROVIDE are now optionally capable of doing something
+ useful: see the documentation string for REQUIRE
+ * infrastructure for a managed SBCL contrib system: contributed
+ modules in this release include:
+ ** the ASDF system definition facility;
+ ** an interface to the BSD Sockets API;
+ ** an ACL-like convenience interface to the repl;
+ (thanks to Kevin Rosenberg)
+ ** an implementation of ROTATE-BYTE, with efficient implementation
+ on x86 hardware;
* fixed a bug in LOG, so that LOG of a rational argument near 1 now
gives a closer approximation to the right answer than previously.
(thanks to Raymond Toy)
* fixed a bug in DEFCLASS: classes named by symbols with no or
unprintable packages can now be defined.
* fixed a bug in RESTART-BIND: The :TEST-FUNCTION option had been
- carelessly renamed to :TEST-FUN. (thanks to Robert E. Brown)
+ carelessly renamed to :TEST-FUN. (thanks to Robert E. Brown)
* fixed compiler failure related to checking types of functions.
(reported by Robert E. Brown)
* the compiler is now much more consistent in its error-checking
by ANSI to operate on sequences.
* fixed a bug in the build procedure: documentation of SBCL-specific
packages is now preserved and available in the final Lisp image.
+ * lifted FDEFINITION lookup out of loops in the implementation of
+ many list operations. (thanks to Robert E. Brown)
+ * fixed a bug in the reader: the #n# reader macro now works for
+ objects of type STANDARD-OBJECT. (reported by Tony Martinez)
+ * the compiler is now aware that SYMBOL-FUNCTION returns a FUNCTION
+ and that READ-DELIMITED-LIST returns a LIST. (thanks to Robert
+ E. Brown and Tony Martinez respectively)
+ * PCL is now smarter about SLOT-VALUE, (SETF SLOT-VALUE) and
+ SLOT-BOUNDP: in particular, it is now able to optimize them much
+ better, and is now not vulnerable to having packages renamed.
+ Furthermore, a compliance bug has been fixed: SLOT-MISSING is now
+ always called when a slot is not present in an instance. (thanks
+ to Gerd Moellmann)
* fixed some bugs revealed by Paul Dietz' test suite:
** ARRAY-IN-BOUNDS-P now allows arbitrary integers as arguments,
not just nonnegative fixnums;
freshly-consed result bit-array);
** ELT now signals an error on an invalid sequence index in safe
code;
- * lifted FDEFINITION lookup out of loops in the implementation of
- many list operations (thanks to Robert E. Brown)
+ ** the type system is now cleverer about negations of numeric
+ types, and consequently understands the BIGNUM and RATIO types
+ better;
planned incompatible changes in 0.7.x:
* (not done yet, but planned:) When the profiling interface settles
