* minor incompatible change: the system no longer provides
optimization hints (conditions which are TYPEP
SB-EXT:COMPILER-NOTE) for conforming code in default compilation
- mode; these hints are emitted when higher SPEED optimization is
- requested, as before.
+ mode; these hints are still emitted when higher SPEED optimization
+ is requested.
+ * new contrib module: a sampling profiler (profiling by statistical
+ sampling, rather than by instrumenting functions) is available as
+ the SB-SPROF contrib. (thanks to Gerd Moellmann and Juho Snellman)
* the behaviour of the standard function ED is now customizeable by
third parties through a hook variable: see ED's documentation
string for information on the protocol.
* the compiler no longer emits efficiency notes for (FUNCALL X)
when the type of X is uncertain under default optimization
settings.
+ * fixed bug 276: mutating a binding of a specialized parameter to a
+ method to something that is not TYPEP the specializer is now
+ possible.
* fixed bugs 45d and 118: DOUBLE-FLOAT[-NEGATIVE]-EPSILON now
exhibit the required behaviour on the x86 platform. (thanks to
Peter van Eynde, Eric Marsden and Bruno Haible)
* fixed another bug in backquote printing: no more destructive
modification of the form's list structure. (reported by Brian
Downing)
+ * fixed bug in INTERRUPT-THREAD: pin the function, so that it cannot
+ move between its address being taken and the call to
+ interrupt_thread, fixing a crashing race condition.
+ * the SB-POSIX contrib implementation has been adjusted so that it
+ no longer exhibits ridiculously poor performance when constructing
+ instances corresponding to C structs.
+
+changes in sbcl-0.8.13 relative to sbcl-0.8.12:
+ * minor incompatible change: as threatened around sbcl-0.8.0, the
+ home package of MOP-related symbols is now SB-MOP, not SB-PCL.
+ The symbols are also exported from SB-PCL for backwards
+ compatibility, but more so than before SB-PCL should be treated as
+ an implementation-internal package.
+ * new feature: SB-PACKAGE-LOCKS. See the fine manual for details,
+ add :SB-PACKAGE-LOCKS in customize-target-features.lisp to
+ enable them.
+ * the SB-SPROF contrib now works on (most) non-x86 architectures.
+ It is known as of this release not to work on the Alpha, however.
+ * fixed bug #338: instances of EQL-SPECIFIER are now valid type
+ designators and can hence be used with TYPEP.
+ * fixed bug #333: CHECK-TYPE now ensures that the type error
+ signalled, if any, has the right object to be accessed by
+ TYPE-ERROR-DATUM. (reported by Tony Martinez)
+ * fixed a bug: #\Space (and other whitespace characters) are no
+ longer considered to be macro characters in standard syntax by
+ GET-MACRO-CHARACTER.
planned incompatible changes in 0.8.x:
* (not done yet, but planned:) When the profiling interface settles
