+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.
+
+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 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
+ * bug fix: GETHASH, (SETF GETHASH), CLRHASH and REMHASH are now
+ interrupt safe.
+ * bug fix: GC race condition occasionally resulting in crashes with
+ the error message "SIG_STOP_FOR_GC blocked at a bad place" has been
+ fixed.
+ * bug fix: &ENVIRONMENT variables in macro lambda lists can now be
+ declared ignored.
+ * bug fix: DEFSETF lambda lists without &ENVIRONMENT no longer cause
+ a STYLE-WARNING to be signalled (regression from 1.0.4.)
+ * bug fix: an asynchronous interrupt could previously leave the
+ 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,
host-ent-addresses -- changing the values did not update the DNS
their NOT- variants no longer cons.
* optimization: EQUAL hash tables no longer use SXHASH for objects
of all data types, but instead use an EQL hash for types for which
- EQUAL is the same as EQL
+ EQUAL is the same as EQL.
* optimization: the non-inlined generic versions of AREF and (SETF AREF)
- are significantly faster
+ are significantly faster.
* optimization: new STRING-OUTPUT-STREAM implementation is much
faster for large outputs and conses 30% less on average.
* enhancement: XREF information is now collected for references made
line in a file is unlimited.
* bug fix: some GC deadlocks caused by asynchronous interrupts have
been fixed by inhibiting interrupts for when GC is disbled.
- * bug fix: GETHASH, (SETF GETHASH), CLRHASH and REMHASH are now
- interrupt safe.
+ * bug fix: some interrupt safety issues with GETHASH, (SETF
+ GETHASH), CLRHASH and REMHASH have been fixed.
* bug fix: binding *BREAK-ON-SIGNALS* to a value that is not a type
specifier no longer causes infinite recursion.
* bug fix: SB-EXT:MUFFLE-CONDITIONS declarations no longer trigger a
- bogus warning in DEFMETHOD bodies (reported by Kevin Reid)
+ bogus warning in DEFMETHOD bodies. (reported by Kevin Reid)
* bug fix: an &environment argument with the correct variable information
- is passed to macros that are expanded during byte compilation

(reported by Samium Gromoff)
* bug fix: a logic error was causing the hash function for bignums to
- have excessive amounts of collisions (reported by Faré Rideau)
+ have excessive amounts of collisions. (reported by Faré Rideau)
* bug fix: modifying the contents of an array could change the return
value of SXHASH on that array, which is only allowed for strings
- and bit vectors (bug introduced in 0.9.16)
- * improvement: the x86-64/darwin port now passes all tests and
- should be considered non-experimental.
+ and bit vectors. (bug introduced in 0.9.16)
+ * improvement: the x86-64/darwin port now passes all tests (except
+ for the debugger tests) but should still be considered
+ experimental until this is fixed.
* improvement: a style-warning is signaled for CASE (etc) clauses with
- duplicate keys (thanks to Kevin Reid)
+ duplicate keys. (thanks to Kevin Reid)
+ * improvement: macos/x86 and macos/x86-64 now use mach exception
+ handlers for dealing with illegal instructions (for trapping and
+ error handling) and memory protection violations (for GC).
changes in sbcl-1.0.4 relative to sbcl-1.0.3:
* new platform: experimental support for x86-64/darwin (MacOS).
