+changes in sbcl-1.0.11 relative to sbcl-1.0.10:
+ * enhancement: CONS can now stack-allocate on x86 and
+ x86-64. (Earlier LIST and LIST* supported stack-allocation, but
+ CONS did not.)
+ * enhancement: nested lists can now be stack allocated on
+ platforms providing stack allocation support.
+ * enhancement: dynamic-extent support has been extended to support
+ cases where there are multiple possible sources for the stack
+ allocated value.
+ * bug fix: symbol-macro expansion now uses the *MACROEXPAND-HOOK*
+ as specified by the CLHS. (thanks to Tobias Rittweiler)
+
changes in sbcl-1.0.10 relative to sbcl-1.0.9:
+ * minor incompatible change: the MSI installer on Windows no longer
+ associates .lisp and .fasl files with the installed SBCL.
* minor incompatible change: :UNIX is no longer present in *FEATURES*
on Windows. (thanks to Luis Oliviera)
- * optimization: SLOT-VALUE and (SETF SLOT-VALUE) are now >20% faster
- for variable slot names, when the class of the instance is
- an instance of STANDARD-CLASS or FUNCALLABLE-STANDARD-CLASS, and not
- any of their subclasses.
+ * new feature: SB-CLTL2 contrib module now implements
+ FUNCTION-INFORMATION. (thanks to Larry D'Anna)
+ * optimization: scavenging weak pointers is now more efficient,
+ requiring O(1) instead of O(N) per weak pointer to identify
+ scanvenged vs. unscavenged pointers. (thanks to Paul Khuong)
+ * optimization: typechecking (SETF SLOT-VALUE) is now ~5x faster in
+ method bodies using constant slot-names when the first argument is
+ a specializer parameter for the method.
+ * optimization: SLOT-VALUE &co are now ~50% faster for variable slot
+ names, when the class of the instance is a direct instance
+ STANDARD-CLASS or FUNCALLABLE-STANDARD-CLASS (making them only 3x
+ as slow as the constant slot-name case.)
* optimization: member type construction is now O(N) instead
of O(N^2).
* optimization: UNION and NUNION are now O(N+M) for large
inputs as long as the :TEST function is one of EQ, EQL, EQUAL, or
EQUALP.
+ * enhancement: DEFINE-MODIFY-MACRO lambda-list information is
+ now more readable in environments like Slime which display it.
+ (thanks to Tobias C. Rittweiler)
+ * bug fix: SB-EXT:COMPARE-AND-SWAP was non-atomic unless the compiler
+ was able to infer the correct argument type for the object on which
+ the CAS operation was being performed.
+ * bug fix: copy propagation interfered with parallel assignment
+ semantics in local calls. (reported by Paul Khuong)
+ * bug fix: the signed modular fixnum shift compiled to wrong code on
+ x86 and x86-64. (spotted by a slight modification to some of
+ PFD's random tests)
changes in sbcl-1.0.9 relative to sbcl-1.0.8:
* minor incompatible change: SB-SYS:OUTPUT-RAW-BYTES is deprecated.
