+changes in sbcl-1.0.5 relative to sbcl-1.0.4:
+ * minor incompatible change: changed experimental JOIN-THREAD interface
+ * documentation: unwinding from asyncronous events has been
+ documented as unsafe.
+ * documentation: SB-SYS:WITHOUT-GCING has been documented as unsafe
+ in multithreaded application code.
+ * bug fix: GC deadlocks from asynchronous interrupts has been fixed
+ by disabling interrupts for the duration of any
+ SB-SYS:WITHOUT-GCING section.
+
+changes in sbcl-1.0.4 relative to sbcl-1.0.3:
+ * new platform: experimental support for x86-64/darwin (MacOS).
+ * incompatible change: the thread-safe (on most platforms) getaddrinfo
+ and getnameinfo sockets functions are used instead of gethostbyaddr
+ and gethostbyname, on platforms where the newer functions are available.
+ As a result, the ALIASES field of HOST-ENT will always be NIL on these
+ platforms.
+ * change: runtimes with embedded cores (i.e. saved with :EXECUTABLE T)
+ don't print the startup banner, but behave as if --noinform was passed
+ as a command line argument. (thanks to Kevin Reid)
+ * new experimental feature: added JOIN-THREAD (by NIIMI Satoshi)
+ * optimization: code using alien values with undeclared types is much faster.
+ * optimization: the compiler is now able to open code SEARCH in more cases.
+ * optimization: more compact typechecks on x86-64 (thanks to Lutz Euler)
+ * bug fix: using standardized COMMON-LISP special variables as loop
+ variables no longer signals bogus package lock violations. (reported
+ by Eric Marsden)
+ * bug fix: declaring local loop variables to be of a range-limited type
+ such as (SINGLE-FLOAT 1.0 2.0) no longer causes a compile-time error.
+ (reported by Andras Simon)
+ * bug fix: >= and <= gave wrong results when used with NaNs. (Some NaN
+ bugs remain on x86-64.)
+ * bug fix: the #= and ## reader macros now interact reasonably with
+ funcallable instances.
+ * bug fix: type-checks for function arguments were compiled using the
+ compiler policy settings of the wrong lexical environment (in 1.0.2
+ and 1.0.3).
+ * bug fix: SHADOW accepts characters as string designators, as required
+ by the spec (thanks to Eric Marsden)
+ * bug fix: fixed GC safety issues when foreign functions are called with
+ non-base strings as arguments
+ * bug fix: more consistent error output for fatal-compiler-warnings, like
+ reader errors
+ * bug fix: functions with proper names were showing up as NIL in
+ backtraces (reported by Edi Weitz, regression in 1.0.2)
+
+changes in sbcl-1.0.3 relative to sbcl-1.0.2:
+ * new platform: NetBSD/PPC. (thanks to Aymeric Vincent)
+ * optimization: calls of the form (AREF FOO (+ INDEX <constant>)) now
+ produce more efficient code on the x86 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.
+ * bug fix: references to undefined variables are handled the same way
+ in toplevel forms as in the normal compiler
+ * bug fix: the build scripts again work with non-bash /bin/sh (thanks
+ to Magnus Henoch)
+ * bug fix: use "gtar" as the asdf-install *TAR-PROGRAM* on NetBSD
+ (thanks to Jon Buller)
+ * improvement: faster compilation times for complex functions
+ * improvement: added readlink support to SB-POSIX (thanks to Richard
+ M Kreuter)
