+changes in sbcl-1.0.8 relative to sbcl-1.0.7:
+ * enhancement: experimental macro SB-EXT:COMPARE-AND-SWAP provides
+ atomic compare-and-swap operations on threaded platforms.
+ * enhancement: experimental function SB-EXT:RESTRICT-COMPILER-POLICY
+ allows assining a global minimum value to optimization qualities
+ (overriding proclamations and declarations).
+ * enhancement: closed over variables can be stack-allocated on x86
+ and x86-64.
+ * performance bug fix: GETHASH and (SETF GETHASH) are once again
+ non-consing.
+ * optimization: STRING-TO-OCTETS is now up to 60% faster for UTF-8.
+ * bug fix: using obsoleted structure instances with TYPEP and
+ generic functions now signals a sensible error.
+ * bug fix: threads waiting on GET-FOREGROUND can be interrupted.
+ (reported by Kristoffer Kvello)
+ * bug fix: backtrace construction is now more careful when making
+ lisp-objects from pointers on the stack, to avoid creating bogus
+ objects that can be seen by the GC.
+ * bug fix: defaulting of values in contexts expecting more than 7
+ variables now works on x86-64. (reported by Christopher Laux)
+ * bug fix: modifications to packages (INTERN, EXPORT, etc) are now
+ thread safe.
+
+changes in sbcl-1.0.7 relative to sbcl-1.0.6:
+ * MOP improvement: support for user-defined subclasses of
+ SB-MOP:SPECIALIZER has been enhanced. The experimental interface
+ function SB-PCL:MAKE-METHOD-SPECIALIZERS-FORM, called as part of
+ the expansion of DEFMETHOD, is responsible for generating a form
+ which creates a list of specializers when evaluated. Additional
+ functions SB-PCL:[UN]PARSE-SPECIALIZER-USING-CLASS provide
+ debugging and introspective support.
+ * minor incompatible change: the (unsupported) spinlock interface
+ has changed: free spinlock now has the value NIL, and a held spinlock
+ has the owning thread as its value.
+ * enhancement: WITHOUT-INTERRUPTS now binds ALLOW-WITH-INTERRUPTS and
+ WITH-LOCAL-INTERRUPTS as local macros. Refer to documentation string
+ for details.
+ * enhancement: name of a socket-stream is now "a socket" instead of
+ "a constant string".
+ * enhancement: SB-POSIX now supports lockf(). (Thanks to Zach Beane.)
+ * enhancement: SB-POSIX now supports getcwd(). (Thanks to Tassilo Horn.)
+ * enhancement: SB-INTROSPECT:FUNCTION-ARGLIST shows nicer argument lists
+ for generic functions. (Thanks to Tobias C. Rittweiler)
+ * optimization: bignum printing speed has been improved by 20-40%
+ (depending on the bignum size.)
+ * bug fix: WITH-MUTEX and WITH-RECURSIVE-LOCK are now interrupt safe
+ on Linux.
+ * bug fix: the cache used by the CLOS to store precomputed effective
+ methods, slot offsets, and constant return values is now thread and
+ interrupt safe.
+ * bug fix: generic function dispatch function updating is now thread
+ and interrupt safe (in the sense that the known issues have been
+ fixed.)
+ * bug fix: ADD/REMOVE-METHOD is now thread and interrupt safe.
+ * bug fix: interning EQL-specializers is now thread and interrupt safe.
+ * bug fix: asdf systems with dependencies to the SB-POSIX or
+ SB-BSD-SOCKETS contribs can be loaded with :FORCE T.
+ * bug fix: interrupt safety of applicable method computation has been
+ improved.
+
changes in sbcl-1.0.6 relative to sbcl-1.0.5:
+ * new contrib: sb-cover, an experimental code coverage tool, is included
+ as a contrib module.
+ * optimization: STRING-TO-OCTETS for unibyte encodings and UTF-8 is
+ significantly faster.
+ * optimization: calls of the form (AREF FOO (+ INDEX <constant>)) now
+ produce more efficient code on x86-64 if the compiler can determine
+ that (+ INDEX <constant>) does not require a bounds check and FOO
+ has an element type at least 8 bits wide.
* enhancement: a new, experimental synchronous timeout facility is
provided. Refer to SB-SYS:WITH-DEADLINE for details.
* enhancement: when a symbol name conflict error arises, the
conflicting symbols are always printed with a package prefix.
(thanks to Kevin Reid)
- * enhancement: stepping is now once again supported on the SPARC. (It is
- also now more likely to work on CheneyGC builds on the PPC.)
- * enhancement: Stepping support on MIPS.
+ * enhancement: stepping is now once again supported on the SPARC and
+ MIPS platforms. (It is also now more likely to work on CheneyGC
+ builds on the PPC.)
+ * enhancement: sb-sprof can now also track and report accurate call
+ counts.
+ * bug fixes: the treatment of non-standard subclasses of
+ SB-MOP:SPECIALIZER is more correct.
* incompatible change: PURIFY no longer copies the data from the
dynamic space into the static and read-only spaces on platforms
that use the generational garbage collector
system running with GC inhibited.
* bug fix: a DECLARE form evaluated at top-level now causes an error
rather than silently (or verbosely) returning NIL.
+ * bug fix: trying to dissassemble functions compiled at high DEBUG could
+ result in a error being signalled due to source form lookup errors.
+ (reported by Peter Graves)
changes in sbcl-1.0.5 relative to sbcl-1.0.4:
* incompatible change: removed writer methods for host-ent-name,
