+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: sb-sprof can now also track and report accurate call
+ counts.
+ * 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
variants no longer cons.
* optimization: Direct calls to CHAR-{EQUAL,LESSP,GREATERP} and
their NOT- variants no longer cons.
- * enhancement: XREF information is now collected to references made
+ * 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.
+ * optimization: the non-inlined generic versions of AREF and (SETF AREF)
+ 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
to global variables using SYMBOL-VALUE and a constant argument.
* enhancement: SIGINT now causes a specific condition
SB-SYS:INTERACTIVE-INTERRUPT to be signalled.
- * bug fix: adding and removing fd-handlers is now thread-safe.
+ * bug fix: FILE-POSITION used to signal an error in some cases where
+ ANSI requires it to return NIL.
+ * bug fix: ADJUST-ARRAY is now interrupt-safe.
+ * bug fix: adding and removing fd-handlers is now interrupt-safe.
* bug fix: inlined calls to C now ensure 16byte stack alignment on
x86/Darwin.
* bug fix: bad type declaration in the CLOS implementation has
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
+ is passed to macros that are expanded during byte compilation.
(reported by Samium Gromoff)
- * improvement: the x86-64/darwin port now passes all tests and
- should be considered non-experimental.
+ * bug fix: a logic error was causing the hash function for bignums to
+ 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 (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).
