+changes relative to sbcl-1.0.57:
+ * enhancement: implicit generic function warnings now specify the package
+ in which the new generic function is being created.
+ * enhancement: SB-EXT:ATOMIC-UPDATE makes it easy to perform non-destructive
+ updates of CAS-able places (similar to Clojure's swap!).
+ * enhancement: run-program no longer decodes and re-encodes environment when
+ :environment argument is not provided. (lp#985904)
+ * enhancement: errors during compiler-macro expansion no longer cause
+ runtime errors, only a compile-time warning, otherwise behaving as if
+ the compiler macro had declined to expand.
+ * optimization: On x86-64, code alignment of block headers is done with
+ multi-byte NOPs now instead of repetitions of the single-byte NOP.
+ * optimization: MAP-INTO is substantially faster when the target sequence is
+ of unknown type; mapping into lists is no longer O(N^2). (thanks to James
+ M. Lawrence)
+ * optimization: the compiler no longer heap-conses to check exits in cases
+ where the exit function is dynamic extent, or when it can prove the exit
+ function cannot escape.
+ * optimization: SB-SEQUENCE:DOSEQUENCE is faster on vectors of unknown
+ element type, and vectors that aren't SIMPLE-ARRAYs.
+ * optimization: CL:SORT and CL:STABLE-SORT are more efficient in execution
+ speed (around 1/3 the time in some cases), and a little better in terms of
+ comparison calls. (Thanks to Takeru Ohta)
+ * bug fix: On SPARC, a limitation on the number of code constants emittable
+ by the compiler has been lifted, allowing certain long functions to
+ compiled and assembled which had previously been unsupported; fixes
+ cl-bench on this ISA (lp#1008996).
+ * bug fix: potential for infinite recursion during compilation of CLOS slot
+ typechecks when dependency graph had loops. (lp#1001799)
+ * bug fix: error forms reported with some program-errors were not escaped
+ properly.
+ * bug fix: functions from EVAL are now on more equal footing with functions
+ from COMPILE. (lp#1000783, lp#851170, lp#922408)
+ * bug fix: ENSURE-GENERIC-METHOD-COMBINATION accepts method combination
+ objects as its :METHOD-COMBINATION argument, not just lists designating
+ method combinations. (lp#936513)
+ * bug fix: run-program no longer unconditionally uses /tmp/ for temporary
+ files. (lp#968837).
+ * bug fix: restore build on solaris/sparc. (lp#1008506)
+ * bug fix: an issue with LDB in the PowerPC backend has been resolved;
+ this fixes an issue found with cl-postgres (thanks to Tomas Hlavaty).
+ * bug fix: compiler-macro lambda-lists specifying non-keyword symbols
+ as keyword arguments no longer accidentally match unevaluated symbols
+ against them.
+ * bug fix: FORMAT used to loop infinitely in some cases when a COLINC
+ parameter was zero, now it signals an error. (lp#905817, fixed since
+ 1.0.56.19)
+ * bug fix: run-program with :pty t no longer makes the pty as the process's
+ controling terminal.

+changes in sbcl-1.0.57 relative to sbcl-1.0.56:
* RANDOM enhancements and bug fixes:
** bug fix: the range and distribution of random integers could be
catastrophically wrong when the compiler derived the type of its
** bug fix: the distribution of random integers is now completely
uniform even when the specified limit is not a power of two.
(Previously some values could be about 0.1 % more probable than
- others in the worst case.)
+ others in the worst case.) (lp#309467)
** RANDOM on large integer arguments is generally faster and conses
less than before; this is visible for fixnums above a length of
about 24 bits, but extremely so for bignums: the old implementation
called with too many arguments.
* enhancement: support for abort(3), exit(3), and _exit(2) has been added to
SB-POSIX.
+ * enhancement: ASDF has been updated 2.21.
* optimization: fewer uses of full calls to signed modular functions.
(lp#903821)
* optimization: typechecking alien values is typically 5 x faster.
allowing faster release of memory back to the OS. (lp#991293)
* bug fix: WITH-DEADLINE (:SECONDS NIL :OVERRIDE T) now drops any
existing deadline for the dynamic scope of its body.
+ * bug fix: compiler-internal interval arithmetic needed to be more
+ conservative about open intervals when operated on by monotonic but not
+ strictly-monotonic functions. (lp#975528)
+ * bug fix: copy-tree caused stack exhaustion on long linear lists, and now
+ it's also slightly faster. (lp#998926)
+ * bug fix: better error messages for malformed declarations.
+ (lp#1000239)
+ * bug fix: define-condition didn't return the name of the defined condition.
* documentation:
** improved docstrings: REPLACE (lp#965592)
* optimization: the compiler no longer refuses to coerce large fixnums to
single floats inline, except on x86 where this limitation is still
necessary.
+ * optimization: truncation operations on integers with constant divisor
+ arguments 1 and -1 are optimized away.
* bug fix: deadlock detection could report the same deadlock twice, for
two different threads. Now a single deadlock is reported exactly once.
* bug fix: interval-arithmetic division during type derivation did not
forms of MAKE-ARRAY with dynamic-extent. (lp#902351)
* bug fix: some of the compile-time side-effects of DEFCLASS were not caught
by package locks.
+ * bug fix: Proper handling of --dynamic-space-size option on 32 bit platforms.
