+changes relative to sbcl-1.0.48:
+ * enhancement: source locations are now available for files loaded as source,
+ compile-time-too evaluation, and initialization files.
+ * enhancement: WITH-COMPILATION-UNIT :SOURCE-NAMESTRING allows providing
+ virtual source-file information, eg. overriding input-file of COMPILE-FILE
+ when a temporary file is used for compilation.
+ * enhancement: ASDF has been updated to version 2.015.1.
+ * enhancement: backtraces involving frames from the default evaluator
+ are more readable.
+ * bug fix: blocking reads from FIFOs created by RUN-PROGRAM were
+ uninterruptible, as well as blocking reads from socket streams created
+ with for which :SERVE-EVENTS NIL. (regression from 1.0.42.43)
+
+changes in sbcl-1.0.48 relative to sbcl-1.0.47:
+ * incompatible change: SB!KERNEL:INSTANCE-LAMBDA, deprecated for over five
+ years, is now no longer supported.

+ could exhaust stack.
+

+ * bug fix: fix mach port rights leaks in mach exception handling code on
+ darwin/x86 and /x86-64. (thanks to Willem Oudshoorn for motivation and the
+ initial patch)

+ * enhancement: (FORMAT "foo" ...) and similar signal a compile-time warning. (lp#327223)
+ * enhancement: no more "in: LAMBDA NIL" messages from the compiler for forms

+ * bug fix: invalid combinations of :PREDICATE and :TYPE options in DEFSTRUCT
+ are detected. (lp#520607)
+ * bug fix: constant keyword argument checking didn't take :ALLOW-OTHER-KEYS
+ into account.
+ * bug fix: SLOT-BOUNDP information is correct during MAKE-INSTANCE in the
+ presence of (SETF SLOT-VALUE-USING-CLASS) and SLOT-BOUNDP-USING-CLASS
+ methods. (regression from 1.0.45.18)

+ CALL-NEXT-METHOD work correctly. (regression from 1.0.45.19)
+ * bug fix: several foreign functions accepting string also accepted NIL and
+ consequently caused a memory fault at 0 now signal a type-error instead.
+ (lp#721087)
+ * bug fix: under rare circumstances, constraint propagation could rewrite a
+ variable reference to refer to a variable not in scope, causing an error
+ during physical environment analysis when attempting to close over the
+ variable. (lp#551227)
+ * bug fix: SIMPLE-CONDITION :FORMAT-CONTROL defaults to NIL.
+
+changes in sbcl-1.0.46 relative to sbcl-1.0.45:

+ &co. (lp#718039)
+ * optimization: ERROR and CERROR are approximately 5 times faster.
+ * optimization: optimized constructors are used for MAKE-INSTANCE of classes

+ * optimization: arithmetic operations with multiple constant arguments in now
+ have them reduced at compile-time. (lp#676414)
+ * optimization: determining current character position on string-streams for
+ pretty-printing was overly slow.
+ * bug fix: local tail calls to DYNAMIC-EXTENT functions can no longer cause
+ lifetime analysis to overwrite closed-over variables (lp#681092).
+ * bug fix: encoding errors from some multibyte external formats such as EUC-JP
+ were not handled correctly (lp#713063).
+ * bug fix: printing waitqueue objects without setting *PRINT-CIRCLE* to T is now
+ safe (lp#673630).

+ * bug fix: UNINTERN takes a symbol, not a symbol designator -- could previously
+ unintern the wrong symbol with the same name. (lp#693796)
+ * bug fix: COPY-PPRINT-DISPATCH always has access to a pristine table,
+ making it possible to restore the initial table if it has been messed up.
+ (lp#678409)
+

+ * enhancement: ~/ and ~user/ are treated specially in pathnames.
+ Refer to documentation for details.
+ * enhancement: ASDF has been updated to version 2.010.
+ * optimization: mutated closed-over variables that are only accessed by
+ DYNAMIC-EXTENT closures (currently only FLET and LABELS functions
+ declared to be DYNAMIC-EXTENT) are stored directly in their containing
+ stack frame, rather than allocating a VALUE-CELL (lp#586103).
+ * optimization: UNWIND-PROTECT cleanup functions are now declared
+ DYNAMIC-EXTENT.
+ * bug fix: backtracing function with &REST arguments now shows the full
+ argument list. (lp#310173)
+ * bug fix: return types for functions with complex lambda-lists are now
+ derived properly (lp#384892)
+ * bug fix: when SPEED > SPACE compiling CONCATENATE 'STRING with constant
+ long string arguments slowed the compiler down to a crawl.
+ * bug fix: closure VALUE-CELLs are no longer stack-allocated (lp#308934).
+ * bug fix: non-standard MAKE-METHOD-LAMBDA methods could break RETURN-FROM
+ in the DEFMETHOD body.

as a place.
* enhancement: ASDF has been updated to 2.009.

+ signalling a full warning about violated proclaimed FTYPEs and violations
+ of derived FTYPEs within the same file, including self-calls.
+ * enhancement: new function: SB-EXT:DELETE-DIRECTORY is now provided.
+ * optimization: constant-folding exploits numeric and character types, in
+ addition member types.
+ * optimization: numeric, character and member types that are inhabited by
+ exactly one value are tested with EQL.
+ * optimization: more conditional branches are eliminated during IR1.
+ Branches are simplified before performing if/if-conversion, and simple
+ equivalent branches (that only read the same constant or variable) are
+ merged.
+ * improvements to the Windows port:
+ ** change: canonical unparsing form for pathname namestrings now uses / as
+ directory separator. NATIVE-NAMESTRING still uses \ as the separator.

+ on Windows. (thanks to Kalyanov Dmitry)
+ ** bug fix: build now works on cygwin with GCC 4.x installed. (thanks to
+ Kalyanov Dmitry)

spuriously when reading from a pipe (lp#643686)
* bug fix: more efficient timer expiry should avoid starvation on systems
where number of SIGALRMs per second is restricted. (lp#375515)

+ to warn when a self-call using the old signature was left in. (lp#655126)
+ * bug fix: incorrect FILE-POSITION on streams opened using :EXTERNAL-FORMAT
+ :DEFAULT when the default external had character size other than 8 bits.
+ (lp#657183)
+ * bug fix: derived types of functions in the same file were implicitly
+ trusted, leading to potential heap corruption when those function were
+ defined incompatibly. (lp#657499)
+ * bug fix: existing ASDF source registries are ignored when building
+ contribs (lp#659105)
+ * bug fix: short-form DEFSETF checks that the second argument is a symbol
+ (lp#655824, thanks to Roman Marynchak)
+ * bug fix: (SETF MACRO-FUNCTION) clobbered macro-definitions before
+ package-lock violation was detected. (lp#660752)
+ * bug fix: the system can store different docstrings for a single function
+ under different names. (lp#661631, regression from 1.0.29.24)
+ * bug fix: source-locations of DEFGENERIC forms weren't getting recorded
+ properly. (lp#384801)

+ fork with multiple Lisp threads running is made on every platform,
+ not just Darwin. (lp#451111)
+ * bug fix: SB-BSD-SOCKETS and SB-SIMPLE-STREAMS could leave stale finalizers
